Chapter 1. OpenID Connect (OIDC) Bearer token authentication
Secure HTTP access to Jakarta REST (formerly known as JAX-RS) endpoints in your application with Bearer token authentication by using the Quarkus OpenID Connect (OIDC) extension.
1.1. Overview of the Bearer token authentication mechanism in Quarkus
Quarkus supports the Bearer token authentication mechanism through the Quarkus OpenID Connect (OIDC) extension.
The bearer tokens are issued by OIDC and OAuth 2.0 compliant authorization servers, such as Keycloak.
Bearer token authentication is the process of authorizing HTTP requests based on the existence and validity of a bearer token. The bearer token provides information about the subject of the call, which is used to determine whether or not an HTTP resource can be accessed.
The following diagrams outline the Bearer token authentication mechanism in Quarkus:
Figure 1.1. Bearer token authentication mechanism in Quarkus with single-page application
- The Quarkus service retrieves verification keys from the OIDC provider. The verification keys are used to verify the bearer access token signatures.
- The Quarkus user accesses the single-page application (SPA).
- The single-page application uses Authorization Code Flow to authenticate the user and retrieve tokens from the OIDC provider.
- The single-page application uses the access token to retrieve the service data from the Quarkus service.
- The Quarkus service verifies the bearer access token signature by using the verification keys, checks the token expiry date and other claims, allows the request to proceed if the token is valid, and returns the service response to the single-page application.
- The single-page application returns the same data to the Quarkus user.
Figure 1.2. Bearer token authentication mechanism in Quarkus with Java or command line client
- The Quarkus service retrieves verification keys from the OIDC provider. The verification keys are used to verify the bearer access token signatures.
-
The client uses
client_credentials
that requires client id and secret or password grant, which requires client id, secret, username, and password to retrieve the access token from the OIDC provider. - The client uses the access token to retrieve the service data from the Quarkus service.
- The Quarkus service verifies the bearer access token signature by using the verification keys, checks the token expiry date and other claims, allows the request to proceed if the token is valid, and returns the service response to the client.
If you need to authenticate and authorize users by using OIDC authorization code flow, see the Quarkus OpenID Connect authorization code flow mechanism for protecting web applications guide. Also, if you use Keycloak and bearer tokens, see the Quarkus Using Keycloak to centralize authorization guide.
To learn about how you can protect service applications by using OIDC Bearer token authentication, see the following tutorial:
For information about how to support multiple tenants, see the Quarkus Using OpenID Connect Multi-Tenancy guide.
1.1.1. Accessing JWT claims
If you need to access JWT token claims, you can inject JsonWebToken
:
package org.acme.security.openid.connect; import org.eclipse.microprofile.jwt.JsonWebToken; import jakarta.inject.Inject; import jakarta.annotation.security.RolesAllowed; import jakarta.ws.rs.GET; import jakarta.ws.rs.Path; import jakarta.ws.rs.Produces; import jakarta.ws.rs.core.MediaType; @Path("/api/admin") public class AdminResource { @Inject JsonWebToken jwt; @GET @RolesAllowed("admin") @Produces(MediaType.TEXT_PLAIN) public String admin() { return "Access for subject " + jwt.getSubject() + " is granted"; } }
Injection of JsonWebToken
is supported in @ApplicationScoped
, @Singleton
, and @RequestScoped
scopes. However, the use of @RequestScoped
is required if the individual claims are injected as simple types. For more information, see the Supported injection scopes section of the Quarkus "Using JWT RBAC" guide.
1.1.2. UserInfo
If you must request a UserInfo JSON object from the OIDC UserInfo
endpoint, set quarkus.oidc.authentication.user-info-required=true
. A request is sent to the OIDC provider UserInfo
endpoint, and an io.quarkus.oidc.UserInfo
(a simple javax.json.JsonObject
wrapper) object is created. io.quarkus.oidc.UserInfo
can be injected or accessed as a SecurityIdentity
userinfo
attribute.
quarkus.oidc.authentication.user-info-required
is automatically enabled if one of these conditions is met:
-
if
quarkus.oidc.roles.source
is set touserinfo
orquarkus.oidc.token.verify-access-token-with-user-info
is set totrue
orquarkus.oidc.authentication.id-token-required
is set tofalse
, the current OIDC tenant must support a UserInfo endpoint in these cases. -
if
io.quarkus.oidc.UserInfo
injection point is detected but only if the current OIDC tenant supports a UserInfo endpoint.
1.1.3. Configuration metadata
The current tenant’s discovered OpenID Connect Configuration Metadata is represented by io.quarkus.oidc.OidcConfigurationMetadata
and can be injected or accessed as a SecurityIdentity
configuration-metadata
attribute.
The default tenant’s OidcConfigurationMetadata
is injected if the endpoint is public.
1.1.4. Token claims and SecurityIdentity roles
You can map SecurityIdentity
roles from the verified JWT access tokens as follows:
-
If the
quarkus.oidc.roles.role-claim-path
property is set, and matching array or string claims are found, then the roles are extracted from these claims. For example,customroles
,customroles/array
,scope
,"http://namespace-qualified-custom-claim"/roles
,"http://namespace-qualified-roles"
. -
If a
groups
claim is available, then its value is used. -
If a
realm_access/roles
orresource_access/client_id/roles
(whereclient_id
is the value of thequarkus.oidc.client-id
property) claim is available, then its value is used. This check supports the tokens issued by Keycloak.
For example, the following JWT token has a complex groups
claim that contains a roles
array that includes roles:
{ "iss": "https://server.example.com", "sub": "24400320", "upn": "jdoe@example.com", "preferred_username": "jdoe", "exp": 1311281970, "iat": 1311280970, "groups": { "roles": [ "microprofile_jwt_user" ], } }
You must map the microprofile_jwt_user
role to SecurityIdentity
roles, and you can do so with this configuration: quarkus.oidc.roles.role-claim-path=groups/roles
.
If the token is opaque (binary), then a scope
property from the remote token introspection response is used.
If UserInfo
is the source of the roles, then set quarkus.oidc.authentication.user-info-required=true
and quarkus.oidc.roles.source=userinfo
, and if needed, set quarkus.oidc.roles.role-claim-path
.
Additionally, a custom SecurityIdentityAugmentor
can also be used to add the roles. For more information, see the Security identity customization section of the Quarkus "Security tips and tricks" guide.
You can also map SecurityIdentity
roles created from token claims to deployment-specific roles by using the HTTP Security policy.
1.1.5. Token scopes and SecurityIdentity permissions
SecurityIdentity
permissions are mapped in the form of io.quarkus.security.StringPermission
from the scope parameter of the source of the roles and using the same claim separator.
import java.util.List; import jakarta.inject.Inject; import jakarta.ws.rs.GET; import jakarta.ws.rs.Path; import org.eclipse.microprofile.jwt.Claims; import org.eclipse.microprofile.jwt.JsonWebToken; import io.quarkus.security.PermissionsAllowed; @Path("/service") public class ProtectedResource { @Inject JsonWebToken accessToken; @PermissionsAllowed("email") 1 @GET @Path("/email") public Boolean isUserEmailAddressVerifiedByUser() { return accessToken.getClaim(Claims.email_verified.name()); } @PermissionsAllowed("orders_read") 2 @GET @Path("/order") public List<Order> listOrders() { return List.of(new Order("1")); } public static class Order { String id; public Order() { } public Order(String id) { this.id = id; } public String getId() { return id; } public void setId() { this.id = id; } } }
For more information about the io.quarkus.security.PermissionsAllowed
annotation, see the Permission annotation section of the "Authorization of web endpoints" guide.
1.1.6. Token verification and introspection
If the token is a JWT token, then, by default, it is verified with a JsonWebKey
(JWK) key from a local JsonWebKeySet
, retrieved from the OIDC provider’s JWK endpoint. The token’s key identifier (kid
) header value is used to find the matching JWK key. If no matching JWK
is available locally, then JsonWebKeySet
is refreshed by fetching the current key set from the JWK endpoint. The JsonWebKeySet
refresh can be repeated only after the quarkus.oidc.token.forced-jwk-refresh-interval
expires. The default expiry time is 10 minutes. If no matching JWK
is available after the refresh, the JWT token is sent to the OIDC provider’s token introspection endpoint.
If the token is opaque, which means it can be a binary token or an encrypted JWT token, then it is always sent to the OIDC provider’s token introspection endpoint.
If you work only with JWT tokens and expect a matching JsonWebKey
to always be available, for example, after refreshing a key set, you must disable token introspection, as shown in the following example:
quarkus.oidc.token.allow-jwt-introspection=false quarkus.oidc.token.allow-opaque-token-introspection=false
There might be cases where JWT tokens must be verified through introspection only, which can be forced by configuring an introspection endpoint address only. The following properties configuration shows you an example of how you can achieve this with Keycloak:
quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus quarkus.oidc.discovery-enabled=false # Token Introspection endpoint: http://localhost:8180/realms/quarkus/protocol/openid-connect/tokens/introspect quarkus.oidc.introspection-path=/protocol/openid-connect/tokens/introspect
There are advantages and disadvantages to indirectly enforcing the introspection of JWT tokens remotely. An advantage is that you eliminate the need for two remote calls: a remote OIDC metadata discovery call followed by another remote call to fetch the verification keys that will not be used. A disadvantage is that you need to know the introspection endpoint address and configure it manually.
The alternative approach is to allow the default option of OIDC metadata discovery but also require that only the remote JWT introspection is performed, as shown in the following example:
quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus quarkus.oidc.token.require-jwt-introspection-only=true
An advantage of this approach is that the configuration is simpler and easier to understand. A disadvantage is that a remote OIDC metadata discovery call is required to discover an introspection endpoint address, even though the verification keys will not be fetched.
The io.quarkus.oidc.TokenIntrospection
, a simple jakarta.json.JsonObject
wrapper object, will be created. It can be injected or accessed as a SecurityIdentity
introspection
attribute, providing either the JWT or opaque token has been successfully introspected.
1.1.7. Token introspection and UserInfo
cache
All opaque access tokens must be remotely introspected. Sometimes, JWT access tokens might also have to be introspected. If UserInfo
is also required, the same access token is used in a subsequent remote call to the OIDC provider. So, if UserInfo
is required, and the current access token is opaque, two remote calls are made for every such token; one remote call to introspect the token and another to get UserInfo
. If the token is JWT, only a single remote call to get UserInfo
is needed, unless it also has to be introspected.
The cost of making up to two remote calls for every incoming bearer or code flow access token can sometimes be problematic.
If this is the case in production, consider caching the token introspection and UserInfo
data for a short period, for example, 3 or 5 minutes.
quarkus-oidc
provides quarkus.oidc.TokenIntrospectionCache
and quarkus.oidc.UserInfoCache
interfaces, usable for @ApplicationScoped
cache implementation. Use @ApplicationScoped
cache implementation to store and retrieve quarkus.oidc.TokenIntrospection
and/or quarkus.oidc.UserInfo
objects, as outlined in the following example:
@ApplicationScoped @Alternative @Priority(1) public class CustomIntrospectionUserInfoCache implements TokenIntrospectionCache, UserInfoCache { ... }
Each OIDC tenant can either permit or deny the storing of its quarkus.oidc.TokenIntrospection
data, quarkus.oidc.UserInfo
data, or both with boolean quarkus.oidc."tenant".allow-token-introspection-cache
and quarkus.oidc."tenant".allow-user-info-cache
properties.
Additionally, quarkus-oidc
provides a simple default memory-based token cache, which implements both quarkus.oidc.TokenIntrospectionCache
and quarkus.oidc.UserInfoCache
interfaces.
You can configure and activate the default OIDC token cache as follows:
# 'max-size' is 0 by default, so the cache can be activated by setting 'max-size' to a positive value: quarkus.oidc.token-cache.max-size=1000 # 'time-to-live' specifies how long a cache entry can be valid for and will be used by a cleanup timer: quarkus.oidc.token-cache.time-to-live=3M # 'clean-up-timer-interval' is not set by default, so the cleanup timer can be activated by setting 'clean-up-timer-interval': quarkus.oidc.token-cache.clean-up-timer-interval=1M
The default cache uses a token as a key, and each entry can have TokenIntrospection
, UserInfo
, or both. It will only keep up to a max-size
number of entries. If the cache is already full when a new entry is to be added, an attempt is made to find a space by removing a single expired entry. Additionally, the cleanup timer, if activated, periodically checks for expired entries and removes them.
You can experiment with the default cache implementation or register a custom one.
1.1.8. JSON Web Token claim verification
After the bearer JWT token’s signature has been verified and its expires at
(exp
) claim has been checked, the iss
(issuer
) claim value is verified next.
By default, the iss
claim value is compared to the issuer
property, which might have been discovered in the well-known provider configuration. However, if the quarkus.oidc.token.issuer
property is set, then the iss
claim value is compared to it instead.
In some cases, this iss
claim verification might not work. For example, if the discovered issuer
property contains an internal HTTP/IP address while the token iss
claim value contains an external HTTP/IP address. Or when a discovered issuer
property contains the template tenant variable, but the token iss
claim value has the complete tenant-specific issuer value.
In such cases, consider skipping the issuer verification by setting quarkus.oidc.token.issuer=any
. Only skip the issuer verification if no other options are available:
-
If you are using Keycloak and observe the issuer verification errors caused by the different host addresses, configure Keycloak with a
KEYCLOAK_FRONTEND_URL
property to ensure the same host address is used. -
If the
iss
property is tenant-specific in a multitenant deployment, use theSecurityIdentity
tenant-id
attribute to check that the issuer is correct in the endpoint or the custom Jakarta filter. For example:
import jakarta.inject.Inject; import jakarta.ws.rs.container.ContainerRequestContext; import jakarta.ws.rs.container.ContainerRequestFilter; import jakarta.ws.rs.core.Response; import jakarta.ws.rs.ext.Provider; import org.eclipse.microprofile.jwt.JsonWebToken; import io.quarkus.oidc.OidcConfigurationMetadata; import io.quarkus.security.identity.SecurityIdentity; @Provider public class IssuerValidator implements ContainerRequestFilter { @Inject OidcConfigurationMetadata configMetadata; @Inject JsonWebToken jwt; @Inject SecurityIdentity identity; public void filter(ContainerRequestContext requestContext) { String issuer = configMetadata.getIssuer().replace("{tenant-id}", identity.getAttribute("tenant-id")); if (!issuer.equals(jwt.getIssuer())) { requestContext.abortWith(Response.status(401).build()); } } }
Consider using the quarkus.oidc.token.audience
property to verify the token aud
(audience
) claim value.
1.1.9. Jose4j Validator
You can register a custom Jose4j Validator to customize the JWT claim verification process, before org.eclipse.microprofile.jwt.JsonWebToken
is initialized. For example:
package org.acme.security.openid.connect; import static org.eclipse.microprofile.jwt.Claims.iss; import io.quarkus.arc.Unremovable; import jakarta.enterprise.context.ApplicationScoped; import org.jose4j.jwt.MalformedClaimException; import org.jose4j.jwt.consumer.JwtContext; import org.jose4j.jwt.consumer.Validator; @Unremovable @ApplicationScoped public class IssuerValidator implements Validator { 1 @Override public String validate(JwtContext jwtContext) throws MalformedClaimException { if (jwtContext.getJwtClaims().hasClaim(iss.name()) && "my-issuer".equals(jwtContext.getJwtClaims().getClaimValueAsString(iss.name()))) { return "wrong issuer"; 2 } return null; 3 } }
Use a @quarkus.oidc.TenantFeature
annotation to bind a custom Validator to a specific OIDC tenant only.
1.1.10. Cross-origin resource sharing
If you plan to use your OIDC service
application from a single-page application running on a different domain, you must configure cross-origin resource sharing (CORS). For more information, see the CORS filter section of the "Cross-origin resource sharing" guide.
1.1.11. Provider endpoint configuration
An OIDC service
application needs to know the OIDC provider’s token, JsonWebKey
(JWK) set, and possibly UserInfo
and introspection endpoint addresses.
By default, they are discovered by adding a /.well-known/openid-configuration
path to the configured quarkus.oidc.auth-server-url
.
Alternatively, if the discovery endpoint is not available, or if you want to save on the discovery endpoint round-trip, you can disable the discovery and configure them with relative path values. For example:
quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus quarkus.oidc.discovery-enabled=false # Token endpoint: http://localhost:8180/realms/quarkus/protocol/openid-connect/token quarkus.oidc.token-path=/protocol/openid-connect/token # JWK set endpoint: http://localhost:8180/realms/quarkus/protocol/openid-connect/certs quarkus.oidc.jwks-path=/protocol/openid-connect/certs # UserInfo endpoint: http://localhost:8180/realms/quarkus/protocol/openid-connect/userinfo quarkus.oidc.user-info-path=/protocol/openid-connect/userinfo # Token Introspection endpoint: http://localhost:8180/realms/quarkus/protocol/openid-connect/tokens/introspect quarkus.oidc.introspection-path=/protocol/openid-connect/tokens/introspect
1.1.12. Token propagation
For information about bearer access token propagation to the downstream services, see the Token propagation section of the Quarkus "OpenID Connect (OIDC) and OAuth2 client and filters reference" guide.
1.1.13. JWT token certificate chain
In some cases, JWT bearer tokens have an x5c
header which represents an X509 certificate chain whose leaf certificate contains a public key that must be used to verify this token’s signature. Before this public key can be accepted to verify the signature, the certificate chain must be validated first. The certificate chain validation involves several steps:
- Confirm that every certificate but the root one is signed by the parent certificate.
- Confirm the chain’s root certificate is also imported in the truststore.
-
Validate the chain’s leaf certificate. If a common name of the leaf certificate is configured then a common name of the chain’s leaf certificate must match it. Otherwise the chain’s leaf certificate must also be avaiable in the truststore, unless one or more custom
TokenCertificateValidator
implementations are registered. -
quarkus.oidc.TokenCertificateValidator
can be used to add a custom certificate chain validation step. It can be used by all tenants expecting tokens with the certificate chain or bound to specific OIDC tenants with the@quarkus.oidc.TenantFeature
annotation.
For example, here is how you can configure Quarkus OIDC to verify the token’s certificate chain, without using quarkus.oidc.TokenCertificateValidator
:
quarkus.oidc.certificate-chain.trust-store-file=truststore-rootcert.p12 1 quarkus.oidc.certificate-chain.trust-store-password=storepassword quarkus.oidc.certificate-chain.leaf-certificate-name=www.quarkusio.com 2
- 1
- The truststore must contain the certificate chain’s root certificate.
- 2
- The certificate chain’s leaf certificate must have a common name equal to
www.quarkusio.com
. If this property is not configured then the truststore must contain the certificate chain’s leaf certificate unless one or more customTokenCertificateValidator
implementations are registered.
You can add a custom certificate chain validation step by registering a custom quarkus.oidc.TokenCertificateValidator
, for example:
package io.quarkus.it.keycloak;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import java.util.List;
import jakarta.enterprise.context.ApplicationScoped;
import io.quarkus.arc.Unremovable;
import io.quarkus.oidc.OidcTenantConfig;
import io.quarkus.oidc.TokenCertificateValidator;
import io.quarkus.oidc.runtime.TrustStoreUtils;
import io.vertx.core.json.JsonObject;
@ApplicationScoped
@Unremovable
public class BearerGlobalTokenChainValidator implements TokenCertificateValidator {
@Override
public void validate(OidcTenantConfig oidcConfig, List<X509Certificate> chain, String tokenClaims) throws CertificateException {
String rootCertificateThumbprint = TrustStoreUtils.calculateThumprint(chain.get(chain.size() - 1));
JsonObject claims = new JsonObject(tokenClaims);
if (!rootCertificateThumbprint.equals(claims.getString("root-certificate-thumbprint"))) { 1
throw new CertificateException("Invalid root certificate");
}
}
}
- 1
- Confirm that the certificate chain’s root certificate is bound to the custom JWT token’s claim.
1.1.14. OIDC provider client authentication
quarkus.oidc.runtime.OidcProviderClient
is used when a remote request to an OIDC provider is required. If introspection of the Bearer token is necessary, then OidcProviderClient
must authenticate to the OIDC provider. For more information about supported authentication options, see the OIDC provider client authentication section in the Quarkus "OpenID Connect authorization code flow mechanism for protecting web applications" guide.
1.1.15. Testing
If you have to test Quarkus OIDC service endpoints that require Keycloak authorization, follow the Test Keycloak authorization section.
You can begin testing by adding the following dependencies to your test project:
Using Maven:
<dependency> <groupId>io.rest-assured</groupId> <artifactId>rest-assured</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>io.quarkus</groupId> <artifactId>quarkus-junit5</artifactId> <scope>test</scope> </dependency>
Using Gradle:
testImplementation("io.rest-assured:rest-assured") testImplementation("io.quarkus:quarkus-junit5")
1.1.15.1. WireMock
Add the following dependencies to your test project:
Using Maven:
<dependency> <groupId>io.quarkus</groupId> <artifactId>quarkus-test-oidc-server</artifactId> <scope>test</scope> </dependency>
Using Gradle:
testImplementation("io.quarkus:quarkus-test-oidc-server")
Prepare the REST test endpoint and set application.properties
. For example:
# keycloak.url is set by OidcWiremockTestResource quarkus.oidc.auth-server-url=${keycloak.url:replaced-by-test-resource}/realms/quarkus/ quarkus.oidc.client-id=quarkus-service-app quarkus.oidc.application-type=service
Finally, write the test code. For example:
import static org.hamcrest.Matchers.equalTo; import java.util.Set; import org.junit.jupiter.api.Test; import io.quarkus.test.common.QuarkusTestResource; import io.quarkus.test.junit.QuarkusTest; import io.quarkus.test.oidc.server.OidcWiremockTestResource; import io.restassured.RestAssured; import io.smallrye.jwt.build.Jwt; @QuarkusTest @QuarkusTestResource(OidcWiremockTestResource.class) public class BearerTokenAuthorizationTest { @Test public void testBearerToken() { RestAssured.given().auth().oauth2(getAccessToken("alice", Set.of("user"))) .when().get("/api/users/me") .then() .statusCode(200) // The test endpoint returns the name extracted from the injected `SecurityIdentity` principal. .body("userName", equalTo("alice")); } private String getAccessToken(String userName, Set<String> groups) { return Jwt.preferredUserName(userName) .groups(groups) .issuer("https://server.example.com") .audience("https://service.example.com") .sign(); } }
The quarkus-test-oidc-server
extension includes a signing RSA private key file in a JSON Web Key
(JWK
) format and points to it with a smallrye.jwt.sign.key.location
configuration property. It allows you to sign the token by using a no-argument sign()
operation.
Testing your quarkus-oidc
service
application with OidcWiremockTestResource
provides the best coverage because even the communication channel is tested against the WireMock HTTP stubs. If you need to run a test with WireMock stubs that are not yet supported by OidcWiremockTestResource
, you can inject a WireMockServer
instance into the test class, as shown in the following example:
OidcWiremockTestResource
does not work with @QuarkusIntegrationTest
against Docker containers because the WireMock server runs in the JVM that runs the test, which is inaccessible from the Docker container that runs the Quarkus application.
package io.quarkus.it.keycloak; import static com.github.tomakehurst.wiremock.client.WireMock.matching; import static org.hamcrest.Matchers.equalTo; import org.junit.jupiter.api.Test; import com.github.tomakehurst.wiremock.WireMockServer; import com.github.tomakehurst.wiremock.client.WireMock; import io.quarkus.test.junit.QuarkusTest; import io.quarkus.test.oidc.server.OidcWireMock; import io.restassured.RestAssured; @QuarkusTest public class CustomOidcWireMockStubTest { @OidcWireMock WireMockServer wireMockServer; @Test public void testInvalidBearerToken() { wireMockServer.stubFor(WireMock.post("/auth/realms/quarkus/protocol/openid-connect/token/introspect") .withRequestBody(matching(".*token=invalid_token.*")) .willReturn(WireMock.aResponse().withStatus(400))); RestAssured.given().auth().oauth2("invalid_token").when() .get("/api/users/me/bearer") .then() .statusCode(401) .header("WWW-Authenticate", equalTo("Bearer")); } }
1.1.16. OidcTestClient
If you use SaaS OIDC providers, such as Auth0
, and want to run tests against the test (development) domain or to run tests against a remote Keycloak test realm, if you already have quarkus.oidc.auth-server-url
configured, you can use OidcTestClient
.
For example, you have the following configuration:
%test.quarkus.oidc.auth-server-url=https://dev-123456.eu.auth0.com/ %test.quarkus.oidc.client-id=test-auth0-client %test.quarkus.oidc.credentials.secret=secret
To start, add the same dependency, quarkus-test-oidc-server
, as described in the WireMock section.
Next, write the test code as follows:
package org.acme; import org.junit.jupiter.api.AfterAll; import static io.restassured.RestAssured.given; import static org.hamcrest.CoreMatchers.is; import java.util.Map; import org.junit.jupiter.api.Test; import io.quarkus.test.junit.QuarkusTest; import io.quarkus.test.oidc.client.OidcTestClient; @QuarkusTest public class GreetingResourceTest { static OidcTestClient oidcTestClient = new OidcTestClient(); @AfterAll public static void close() { oidcTestClient.close(); } @Test public void testHelloEndpoint() { given() .auth().oauth2(getAccessToken("alice", "alice")) .when().get("/hello") .then() .statusCode(200) .body(is("Hello, Alice")); } private String getAccessToken(String name, String secret) { return oidcTestClient.getAccessToken(name, secret, Map.of("audience", "https://dev-123456.eu.auth0.com/api/v2/", "scope", "profile")); } }
This test code acquires a token by using a password
grant from the test Auth0
domain, which has registered an application with the client id test-auth0-client
, and created the user alice
with password alice
. For a test like this to work, the test Auth0
application must have the password
grant enabled. This example code also shows how to pass additional parameters. For Auth0
, these are the audience
and scope
parameters.
1.1.16.1. Dev Services for Keycloak
The preferred approach for integration testing against Keycloak is Dev Services for Keycloak. Dev Services for Keycloak
will start and initialize a test container. Then, it will create a quarkus
realm and a quarkus-app
client (secret
secret) and add alice
(admin
and user
roles) and bob
(user
role) users, where all of these properties can be customized.
First, add the following dependency, which provides a utility class io.quarkus.test.keycloak.client.KeycloakTestClient
that you can use in tests for acquiring the access tokens:
Using Maven:
<dependency> <groupId>io.quarkus</groupId> <artifactId>quarkus-test-keycloak-server</artifactId> <scope>test</scope> </dependency>
Using Gradle:
testImplementation("io.quarkus:quarkus-test-keycloak-server")
Next, prepare your application.properties
configuration file. You can start with an empty application.properties
file because Dev Services for Keycloak
registers quarkus.oidc.auth-server-url
and points it to the running test container, quarkus.oidc.client-id=quarkus-app
, and quarkus.oidc.credentials.secret=secret
.
However, if you have already configured the required quarkus-oidc
properties, then you only need to associate quarkus.oidc.auth-server-url
with the prod
profile for `Dev Services for Keycloak`to start a container, as shown in the following example:
%prod.quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus
If a custom realm file has to be imported into Keycloak before running the tests, configure Dev Services for Keycloak
as follows:
%prod.quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus quarkus.keycloak.devservices.realm-path=quarkus-realm.json
Finally, write your test, which will be executed in JVM mode, as shown in the following examples:
Example of a test executed in JVM mode:
package org.acme.security.openid.connect; import io.quarkus.test.junit.QuarkusTest; import io.quarkus.test.keycloak.client.KeycloakTestClient; import io.restassured.RestAssured; import org.junit.jupiter.api.Test; @QuarkusTest public class BearerTokenAuthenticationTest { KeycloakTestClient keycloakClient = new KeycloakTestClient(); @Test public void testAdminAccess() { RestAssured.given().auth().oauth2(getAccessToken("alice")) .when().get("/api/admin") .then() .statusCode(200); RestAssured.given().auth().oauth2(getAccessToken("bob")) .when().get("/api/admin") .then() .statusCode(403); } protected String getAccessToken(String userName) { return keycloakClient.getAccessToken(userName); } }

1.1.16.2. Local public key
You can use a local inlined public key for testing your quarkus-oidc
service
applications, as shown in the following example:
quarkus.oidc.client-id=test quarkus.oidc.public-key=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAlivFI8qB4D0y2jy0CfEqFyy46R0o7S8TKpsx5xbHKoU1VWg6QkQm+ntyIv1p4kE1sPEQO73+HY8+Bzs75XwRTYL1BmR1w8J5hmjVWjc6R2BTBGAYRPFRhor3kpM6ni2SPmNNhurEAHw7TaqszP5eUF/F9+KEBWkwVta+PZ37bwqSE4sCb1soZFrVz/UT/LF4tYpuVYt3YbqToZ3pZOZ9AX2o1GCG3xwOjkc4x0W7ezbQZdC9iftPxVHR8irOijJRRjcPDtA6vPKpzLl6CyYnsIYPd99ltwxTHjr3npfv/3Lw50bAkbT4HeLFxTx4flEoZLKO/g0bAoV2uqBhkA9xnQIDAQAB smallrye.jwt.sign.key.location=/privateKey.pem
To generate JWT tokens, copy privateKey.pem
from the integration-tests/oidc-tenancy
in the main
Quarkus repository and use a test code similar to the one in the preceding WireMock section. You can use your own test keys, if preferred.
This approach provides limited coverage compared to the WireMock approach. For example, the remote communication code is not covered.
1.1.16.3. TestSecurity annotation
You can use @TestSecurity
and @OidcSecurity
annotations to test the service
application endpoint code, which depends on either one, or all three, of the following injections:
-
JsonWebToken
-
UserInfo
-
OidcConfigurationMetadata
First, add the following dependency:
Using Maven:
<dependency> <groupId>io.quarkus</groupId> <artifactId>quarkus-test-security-oidc</artifactId> <scope>test</scope> </dependency>
Using Gradle:
testImplementation("io.quarkus:quarkus-test-security-oidc")
Write a test code as outlined in the following example:
import static org.hamcrest.Matchers.is; import org.junit.jupiter.api.Test; import io.quarkus.test.common.http.TestHTTPEndpoint; import io.quarkus.test.junit.QuarkusTest; import io.quarkus.test.security.TestSecurity; import io.quarkus.test.security.oidc.Claim; import io.quarkus.test.security.oidc.ConfigMetadata; import io.quarkus.test.security.oidc.OidcSecurity; import io.quarkus.test.security.oidc.UserInfo; import io.restassured.RestAssured; @QuarkusTest @TestHTTPEndpoint(ProtectedResource.class) public class TestSecurityAuthTest { @Test @TestSecurity(user = "userOidc", roles = "viewer") public void testOidc() { RestAssured.when().get("test-security-oidc").then() .body(is("userOidc:viewer")); } @Test @TestSecurity(user = "userOidc", roles = "viewer") @OidcSecurity(claims = { @Claim(key = "email", value = "user@gmail.com") }, userinfo = { @UserInfo(key = "sub", value = "subject") }, config = { @ConfigMetadata(key = "issuer", value = "issuer") }) public void testOidcWithClaimsUserInfoAndMetadata() { RestAssured.when().get("test-security-oidc-claims-userinfo-metadata").then() .body(is("userOidc:viewer:user@gmail.com:subject:issuer")); } }
The ProtectedResource
class, which is used in this code example, might look like this:
import jakarta.inject.Inject; import jakarta.ws.rs.GET; import jakarta.ws.rs.Path; import io.quarkus.oidc.OidcConfigurationMetadata; import io.quarkus.oidc.UserInfo; import io.quarkus.security.Authenticated; import org.eclipse.microprofile.jwt.JsonWebToken; @Path("/service") @Authenticated public class ProtectedResource { @Inject JsonWebToken accessToken; @Inject UserInfo userInfo; @Inject OidcConfigurationMetadata configMetadata; @GET @Path("test-security-oidc") public String testSecurityOidc() { return accessToken.getName() + ":" + accessToken.getGroups().iterator().next(); } @GET @Path("test-security-oidc-claims-userinfo-metadata") public String testSecurityOidcWithClaimsUserInfoMetadata() { return accessToken.getName() + ":" + accessToken.getGroups().iterator().next() + ":" + accessToken.getClaim("email") + ":" + userInfo.getString("sub") + ":" + configMetadata.get("issuer"); } }
You must always use the @TestSecurity
annotation. Its user
property is returned as JsonWebToken.getName()
and its roles
property is returned as JsonWebToken.getGroups()
. The @OidcSecurity
annotation is optional and you can use it to set the additional token claims and the UserInfo
and OidcConfigurationMetadata
properties. Additionally, if the quarkus.oidc.token.issuer
property is configured, it is used as an OidcConfigurationMetadata
issuer
property value.
If you work with opaque tokens, you can test them as shown in the following code example:
import static org.hamcrest.Matchers.is; import org.junit.jupiter.api.Test; import io.quarkus.test.common.http.TestHTTPEndpoint; import io.quarkus.test.junit.QuarkusTest; import io.quarkus.test.security.TestSecurity; import io.quarkus.test.security.oidc.OidcSecurity; import io.quarkus.test.security.oidc.TokenIntrospection; import io.restassured.RestAssured; @QuarkusTest @TestHTTPEndpoint(ProtectedResource.class) public class TestSecurityAuthTest { @Test @TestSecurity(user = "userOidc", roles = "viewer") @OidcSecurity(introspectionRequired = true, introspection = { @TokenIntrospection(key = "email", value = "user@gmail.com") } ) public void testOidcWithClaimsUserInfoAndMetadata() { RestAssured.when().get("test-security-oidc-opaque-token").then() .body(is("userOidc:viewer:userOidc:viewer:user@gmail.com")); } }
The ProtectedResource
class, which is used in this code example, might look like this:
import jakarta.inject.Inject; import jakarta.ws.rs.GET; import jakarta.ws.rs.Path; import io.quarkus.oidc.TokenIntrospection; import io.quarkus.security.Authenticated; import io.quarkus.security.identity.SecurityIdentity; @Path("/service") @Authenticated public class ProtectedResource { @Inject SecurityIdentity securityIdentity; @Inject TokenIntrospection introspection; @GET @Path("test-security-oidc-opaque-token") public String testSecurityOidcOpaqueToken() { return securityIdentity.getPrincipal().getName() + ":" + securityIdentity.getRoles().iterator().next() + ":" + introspection.getString("username") + ":" + introspection.getString("scope") + ":" + introspection.getString("email"); } }
The @TestSecurity
, user
, and roles
attributes are available as TokenIntrospection
, username
, and scope
properties. Use io.quarkus.test.security.oidc.TokenIntrospection
to add the additional introspection response properties, such as an email
, and so on.
@TestSecurity
and @OidcSecurity
can be combined in a meta-annotation, as outlined in the following example:
@Retention(RetentionPolicy.RUNTIME) @Target({ ElementType.METHOD }) @TestSecurity(user = "userOidc", roles = "viewer") @OidcSecurity(introspectionRequired = true, introspection = { @TokenIntrospection(key = "email", value = "user@gmail.com") } ) public @interface TestSecurityMetaAnnotation { }
This is particularly useful if multiple test methods must use the same set of security settings.
1.1.17. Check errors in the logs
To see more details about token verification errors, enable io.quarkus.oidc.runtime.OidcProvider
and TRACE
level logging:
quarkus.log.category."io.quarkus.oidc.runtime.OidcProvider".level=TRACE quarkus.log.category."io.quarkus.oidc.runtime.OidcProvider".min-level=TRACE
To see more details about OidcProvider
client initialization errors, enable io.quarkus.oidc.runtime.OidcRecorder
and TRACE
level logging as follows:
quarkus.log.category."io.quarkus.oidc.runtime.OidcRecorder".level=TRACE quarkus.log.category."io.quarkus.oidc.runtime.OidcRecorder".min-level=TRACE
1.1.18. External and internal access to OIDC providers
The externally-accessible token of the OIDC provider and other endpoints might have different HTTP(S) URLs compared to the URLs that are auto-discovered or configured relative to the quarkus.oidc.auth-server-url
internal URL. For example, suppose your SPA acquires a token from an external token endpoint address and sends it to Quarkus as a bearer token. In that case, the endpoint might report an issuer verification failure.
In such cases, if you work with Keycloak, start it with the KEYCLOAK_FRONTEND_URL
system property set to the externally accessible base URL. If you work with other OIDC providers, refer to your provider’s documentation.
1.1.19. Using the client-id
property
The quarkus.oidc.client-id
property identifies the OIDC client that requested the current bearer token. The OIDC client can be an SPA application running in a browser or a Quarkus web-app
confidential client application propagating the access token to the Quarkus service
application.
This property is required if the service
application is expected to introspect the tokens remotely, which is always the case for the opaque tokens. This property is optional for local JSON Web Token (JWT) verification only.
Setting the quarkus.oidc.client-id
property is encouraged even if the endpoint does not require access to the remote introspection endpoint. This is because when client-id
is set, it can be used to verify the token audience. It will also be included in logs when the token verification fails, enabling better traceability of tokens issued to specific clients and analysis over a longer period.
For example, if your OIDC provider sets a token audience, consider the following configuration pattern:
# Set client-id quarkus.oidc.client-id=quarkus-app # Token audience claim must contain 'quarkus-app' quarkus.oidc.token.audience=${quarkus.oidc.client-id}
If you set quarkus.oidc.client-id
, but your endpoint does not require remote access to one of the OIDC provider endpoints (introspection, token acquisition, and so on), do not set a client secret with quarkus.oidc.credentials
or similar properties because it will not be used.
Quarkus web-app
applications always require the quarkus.oidc.client-id
property.
1.2. Authentication after an HTTP request has completed
Sometimes, SecurityIdentity
for a given token must be created when there is no active HTTP request context. The quarkus-oidc
extension provides io.quarkus.oidc.TenantIdentityProvider
to convert a token to a SecurityIdentity
instance. For example, one situation when you must verify the token after the HTTP request has completed is when you are processing messages with Vert.x event bus. The example below uses the 'product-order' message within different CDI request contexts. Therefore, an injected SecurityIdentity
would not correctly represent the verified identity and be anonymous.
package org.acme.quickstart.oidc;
import static jakarta.ws.rs.core.HttpHeaders.AUTHORIZATION;
import jakarta.inject.Inject;
import jakarta.ws.rs.HeaderParam;
import jakarta.ws.rs.POST;
import jakarta.ws.rs.Path;
import io.vertx.core.eventbus.EventBus;
@Path("order")
public class OrderResource {
@Inject
EventBus eventBus;
@POST
public void order(String product, @HeaderParam(AUTHORIZATION) String bearer) {
String rawToken = bearer.substring("Bearer ".length()); 1
eventBus.publish("product-order", new Product(product, rawToken));
}
public static class Product {
public String product;
public String customerAccessToken;
public Product() {
}
public Product(String product, String customerAccessToken) {
this.product = product;
this.customerAccessToken = customerAccessToken;
}
}
}
- 1
- At this point, the token is not verified when proactive authentication is disabled.
package org.acme.quickstart.oidc; import jakarta.enterprise.context.ApplicationScoped; import jakarta.inject.Inject; import io.quarkus.oidc.AccessTokenCredential; import io.quarkus.oidc.Tenant; import io.quarkus.oidc.TenantIdentityProvider; import io.quarkus.security.identity.SecurityIdentity; import io.quarkus.vertx.ConsumeEvent; import io.smallrye.common.annotation.Blocking; @ApplicationScoped public class OrderService { @Tenant("tenantId") @Inject TenantIdentityProvider identityProvider; @Inject TenantIdentityProvider defaultIdentityProvider; 1 @Blocking @ConsumeEvent("product-order") void processOrder(OrderResource.Product product) { AccessTokenCredential tokenCredential = new AccessTokenCredential(product.customerAccessToken); SecurityIdentity securityIdentity = identityProvider.authenticate(tokenCredential).await().indefinitely(); 2 ... } }
When the provider is used during an HTTP request, the tenant configuration can be resolved as described in the Using OpenID Connect Multi-Tenancy guide. However, when there is no active HTTP request, you must select the tenant explicitly with the io.quarkus.oidc.Tenant
qualifier.
Dynamic tenant configuration resolution is currently not supported. Authentication that requires a dynamic tenant will fail.
1.3. OIDC request filters
You can filter OIDC requests made by Quarkus to the OIDC provider by registering one or more OidcRequestFilter
implementations, which can update or add new request headers, and log requests. For more information, see OIDC request filters.
