2.2.3. Additional Camel Quarkus configuration
Copia collegamento

Beyond standard usages known from vanilla Camel, Camel Quarkus adds the possibility to parse the Avro schema at build time both in JVM and Native mode.

The approach to generate Avro classes from Avro schema files is the one coined by the quarkus-avro extension. It requires the following:

  1. Store *.avsc files in a folder named src/main/avro or src/test/avro

  2. In addition to the usual build goal of quarkus-maven-plugin, add the generate-code goal: 

    <plugin>
    <groupId>io.quarkus</groupId>
    <artifactId>quarkus-maven-plugin</artifactId>
    <executions>
        <execution>
            <id>generate-code-and-build</id>
            <goals>
                <goal>generate-code</goal>
                <goal>build</goal>
            </goals>
        </execution>

  1. The client type apache has to be selected by configuring the following property: 

    quarkus.dynamodb.sync-client.type=apache
    Copy to Clipboard Toggle word wrap

  2. The DynamoDbClient has to be made "unremovable" in the sense of Quarkus CDI reference so that Camel Quarkus is able to look it up at runtime. You can reach that e.g. by adding a dummy bean injecting DynamoDbClient: 

    import javax.enterprise.context.ApplicationScoped;
import io.quarkus.arc.Unremovable;
import software.amazon.awssdk.services.dynamodb.DynamoDbClient;

2.12.3. Usage
Copia collegamento

2.12.3.1. Configuring the ValidatorFactory
Copia collegamento

Implementation of this extension leverages the Quarkus Hibernate Validator extension.

Therefore it is not possible to configure the ValidatorFactory by Camel’s properties (constraintValidatorFactory, messageInterpolator, traversableResolver, validationProviderResolver and validatorFactory).

You can configure the ValidatorFactory by the creation of beans which will be injected into the default ValidatorFactory (created by Quarkus). See the Quarkus CDI documentation for more information.

2.12.3.2. Custom validation groups in native mode
Copia collegamento

When using custom validation groups in native mode, all the interfaces need to be registered for reflection (see the documentation).

Example: 

@RegisterForReflection
public interface OptionalChecks {
}
Copy to Clipboard Toggle word wrap

2.12.4. Camel Quarkus limitations
Copia collegamento

It is not possible to describe your constraints as XML (by providing the file META-INF/validation.xml), only Java annotations are supported. This is caused by the limitation of the Quarkus Hibernate Validator extension (see the issue).

2.13. Bean
Copia collegamento

Invoke methods of Java beans

2.13.1. What’s inside
Copia collegamento

Please refer to the above links for usage and configuration details.

</dependency>
Copy to Clipboard Toggle word wrap

2.14.3. Camel Quarkus limitations
Copia collegamento

When using camel-quarkus-bindy in native mode, only the build machine’s locale is supported.

For instance, on build machines with french locale, the code below: 

BindyDataFormat dataFormat = new BindyDataFormat();
dataFormat.setLocale("ar");
Copy to Clipboard Toggle word wrap

formats numbers the arabic way in JVM mode as expected. However, it formats numbers the french way in native mode.

Without further tuning, the build machine’s default locale would be used. Another locale could be specified with the quarkus.native.user-language and quarkus.native.user-country configuration properties.

2.15. Browse

2.16.3. Additional Camel Quarkus configuration
Copia collegamento

2.16.3.1. Cassandra aggregation repository in native mode
Copia collegamento

In order to use Cassandra aggregation repositories like CassandraAggregationRepository in native mode, you must enable native serialization support.

In addition, if your exchange bodies are custom types, then they must be registered for serialization by annotating their class declaration with @RegisterForReflection(serialization = true).

2.17. Control Bus

2.17.3. Usage
Copia collegamento

2.17.3.1. Languages
Copia collegamento

The following languages are supported for use in the Control Bus extension in Camel Extensions for Quarkus:

2.17.3.1.1. Bean
Copia collegamento

The Bean language can be used to invoke a method on a bean to control the state of routes. The org.apache.camel.quarkus:camel-quarkus-bean extension must be added to the classpath. Maven users must add the following dependency to the POM: 

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-bean</artifactId>
</dependency>
Copy to Clipboard Toggle word wrap

In native mode, the bean class must be annotated with @RegisterForReflection.

2.17.3.1.2. Simple
Copia collegamento

The Simple language can be used to control the state of routes. The following example uses a ProducerTemplate to stop a route with the id foo: 

template.sendBody(
    "controlbus:language:simple",
    "${camelContext.getRouteController().stopRoute('foo')}"
);
Copy to Clipboard Toggle word wrap

To use the OGNL notation, the org.apache.camel.quarkus:camel-quarkus-bean extension must be added as a dependency.

In native mode, the classes used in the OGNL notation must be registered for reflection. In the above code snippet, the org.apache.camel.spi.RouteController class returned from camelContext.getRouteController() must be registered. As this is a third-party class, it cannot be annotated with @RegisterForReflection directly - instead you can annotate a different class and specifying the target classes to register. For example, the class defining the Camel routes could be annotated with @RegisterForReflection(targets = { org.apache.camel.spi.RouteController.class }).

Alternatively, add the following line to your src/main/resources/application.properties: 

quarkus.camel.native.reflection.include-patterns = org.apache.camel.spi.RouteController

2.18.3. Additional Camel Quarkus configuration
Copia collegamento

2.18.3.1. Simple language
Copia collegamento

2.18.3.1.1. Using the OGNL notation
Copia collegamento

When using the OGNL notation from the simple language, the camel-quarkus-bean extension should be used.

For instance, the simple expression below is accessing the getAddress() method on the message body of type Client. 

---
simple("${body.address}")
---
Copy to Clipboard Toggle word wrap

In such a situation, one should take an additional dependency on the camel-quarkus-bean extension as described here. Note that in native mode, some classes may need to be registered for reflection. In the example above, the Client class needs to be registered for reflection.

2.18.3.1.2. Using dynamic type resolution in native mode
Copia collegamento

When dynamically resolving a type from simple expressions like:

  • simple("${mandatoryBodyAs(TYPE)}")
  • simple("${type:package.Enum.CONSTANT}")
  • from("…​").split(bodyAs(TYPE.class))
  • simple("${body} is TYPE")

It may be needed to register some classes for reflection manually.

For instance, the simple expression below is dynamically resolving the type java.nio.ByteBuffer at runtime: 

---
simple("${body} is 'java.nio.ByteBuffer'")
---
Copy to Clipboard Toggle word wrap

As such, the class java.nio.ByteBuffer needs to be registered for reflection.

2.18.3.1.3. Using the simple language with classpath resources in native mode
Copia collegamento

If your route is supposed to load a Simple script from classpath, like in the following example 

from("direct:start").transform().simple("resource:classpath:mysimple.txt");
Copy to Clipboard Toggle word wrap

then you need to use Quarkus quarkus.native.resources.includes property to include the resource in the native executable as demonstrated below: 

quarkus.native.resources.includes = mysimple.txt
Copy to Clipboard Toggle word wrap
2.18.3.1.4. Configuring a custom bean via properties in native mode
Copia collegamento

When specifying a custom bean via properties in native mode with configuration like #class:* or #type:*, it may be needed to register some classes for reflection manually.

For instance, the custom bean definition below involves the use of reflection for bean instantiation and setter invocation: 

---
camel.beans.customBeanWithSetterInjection = #class:org.example.PropertiesCustomBeanWithSetterInjection
camel.beans.customBeanWithSetterInjection.counter = 123
---
Copy to Clipboard Toggle word wrap

As such, the class PropertiesCustomBeanWithSetterInjection needs to be registered for reflection, note that field access could be omitted in this case.

lock quarkus.camel.service.discovery.exclude-patterns

A comma-separated list of Ant-path style patterns to match Camel service definition files in the classpath. The services defined in the matching files will not be discoverable via the org.apache.camel.spi.FactoryFinder mechanism. The excludes have higher precedence than includes. The excludes defined here can also be used to veto the discoverability of services included by Camel Quarkus extensions. Example values: META-INF/services/org/apache/camel/foo/*,META-INF/services/org/apache/camel/foo/**/bar

string

 

lock quarkus.camel.service.discovery.include-patterns

A comma-separated list of Ant-path style patterns to match Camel service definition files in the classpath. The services defined in the matching files will be discoverable via the org.apache.camel.spi.FactoryFinder mechanism unless the given file is excluded via exclude-patterns. Note that Camel Quarkus extensions may include some services by default. The services selected here added to those services and the exclusions defined in exclude-patterns are applied to the union set. Example values: META-INF/services/org/apache/camel/foo/*,META-INF/services/org/apache/camel/foo/**/bar

string

 

lock quarkus.camel.service.registry.exclude-patterns

A comma-separated list of Ant-path style patterns to match Camel service definition files in the classpath. The services defined in the matching files will not be added to Camel registry during application’s static initialization. The excludes have higher precedence than includes. The excludes defined here can also be used to veto the registration of services included by Camel Quarkus extensions. Example values: META-INF/services/org/apache/camel/foo/*,META-INF/services/org/apache/camel/foo/**/bar

string

 

lock quarkus.camel.service.registry.include-patterns

A comma-separated list of Ant-path style patterns to match Camel service definition files in the classpath. The services defined in the matching files will be added to Camel registry during application’s static initialization unless the given file is excluded via exclude-patterns. Note that Camel Quarkus extensions may include some services by default. The services selected here added to those services and the exclusions defined in exclude-patterns are applied to the union set. Example values: META-INF/services/org/apache/camel/foo/*,META-INF/services/org/apache/camel/foo/**/bar

Use the class name format as returned by the java.lang.Class.getName() method: package segments delimited by period . and inner classes by dollar sign $. This option narrows down the set selected by include-patterns. By default, no classes are excluded. This option cannot be used to unregister classes which have been registered internally by Quarkus extensions.

lock quarkus.camel.native.reflection.include-patterns

A comma separated list of Ant-path style patterns to match class names that should be registered for reflection. Use the class name format as returned by the java.lang.Class.getName() method: package segments delimited by period . and inner classes by dollar sign $. By default, no classes are included. The set selected by this option can be narrowed down by exclude-patterns. Note that Quarkus extensions typically register the required classes for reflection by themselves. This option is useful in situations when the built in functionality is not sufficient. Note that this option enables the full reflective access for constructors, fields and methods. If you need a finer grained control, consider using io.quarkus.runtime.annotations.RegisterForReflection annotation in your Java code. For this option to work properly, at least one of the following conditions must be satisfied: - There are no wildcards (* or /) in the patterns - The artifacts containing the selected classes contain a Jandex index (META-INF/jandex.idx) - The artifacts containing the selected classes are registered for indexing using the quarkus.index-dependency.* family of options in application.properties - e.g. quarkus.index-dependency.my-dep.group-id = org.my-group quarkus.index-dependency.my-dep.artifact-id = my-artifact where my-dep is a label of your choice to tell Quarkus that org.my-group and with my-artifact belong together.

        JacksonDataFormat dataFormat = new JacksonDataFormat();
        dataFormat.setObjectMapper(mapper);
        // Use the dataFormat instance in a route definition
        from("direct:my-direct").marshal(dataFormat)
    }
}

import org.apache.camel.component.jackson.JacksonDataFormat;

public class Routes extends RouteBuilder {
    public void configure() {
        JacksonDataFormat dataFormat = new JacksonDataFormat();
        // Make JacksonDataFormat discover the Quarkus Jackson `ObjectMapper` from the Camel registry
        dataFormat.setAutoDiscoverObjectMapper(true);
        // Use the dataFormat instance in a route definition
        from("direct:my-direct").marshal(dataFormat)
    }
}

        restConfiguration().dataFormatProperty("autoDiscoverObjectMapper", "true");
        // REST definition follows...
    }
}

Note

Connection pooling is a Technical Preview feature in this release of Camel Extensions for Quarkus.

To use connection pooling in the camel-quarkus-jms components, you must add io.quarkiverse.artemis:quarkus-artemis-jms and io.quarkiverse.messaginghub:quarkus-pooled-jms to your pom.xml and set the following configuration: 

quarkus.pooled-jms.max-connections = 8
Copy to Clipboard Toggle word wrap

You can use the quarkus-pooled-jms extension to get pooling and XA support for JMS connections. Refer to the quarkus-pooled-jms extension documentation for more information. Currently, it only works with quarkus-artemis-jms extension. Just add these two dependencies to your pom.xml: 

<dependency>
    <groupId>io.quarkiverse.messaginghub</groupId>
    <artifactId>quarkus-pooled-jms</artifactId>
</dependency>
<dependency>
    <groupId>io.quarkiverse.artemis</groupId>
    <artifactId>quarkus-artemis-jms</artifactId>
    <version>2.0.1</version>
</dependency>
Copy to Clipboard Toggle word wrap
Note

Pooling is enabled by default.

To enable XA, you need to add the following configuration to your application.properties: 

quarkus.pooled-jms.xa.enabled=true
Copy to Clipboard Toggle word wrap
Note

clientID and durableSubscriptionName are not supported in pooling connections. If setClientID is called on a reused connection from the pool, an IllegalStateException will be thrown. You will get some error messages such like Cause: setClientID can only be called directly after the connection is created

2.37.4. transferException option in native mode
Copia collegamento

To use the transferException option in native mode, you must enable support for object serialization. Refer to the native mode user guide for more information.

You will also need to enable serialization for the exception classes that you intend to serialize. For example. 

@RegisterForReflection(targets = { IllegalStateException.class, MyCustomException.class }, serialization = true)

2.41.3. allowContextMapAll option in native mode
Copia collegamento

The allowContextMapAll option is not supported in native mode as it requires reflective access to security sensitive camel core classes such as CamelContext & Exchange. This is considered a security risk and thus access to the feature is not provided by default.

2.41.4. Additional Camel Quarkus configuration
Copia collegamento

2.41.4.1. Loading JSLT templates from classpath in native mode
Copia collegamento

This component typically loads the templates from classpath. To make it work also in native mode, you need to explicitly embed the templates files in the native executable by using the quarkus.native.resources.includes property.

For instance, the route below would load the JSLT schema from a classpath resource named transformation.json: 

from("direct:start").to("jslt:transformation.json");
Copy to Clipboard Toggle word wrap

To include this (an possibly other templates stored in .json files) in the native image, you would have to add something like the following to your application.properties file: 

quarkus.native.resources.includes = *.json
Copy to Clipboard Toggle word wrap

2.41.4.2. Using JSLT functions in native mode
Copia collegamento

When using JSLT functions from camel-quarkus in native mode, the classes hosting the functions would need to be registered for reflection. When registering the target function is not possible, one may end up writing a stub as below. 

@RegisterForReflection
public class MathFunctionStub {
    public static double pow(double a, double b) {
        return java.lang.Math.pow(a, b);
    }
}
Copy to Clipboard Toggle word wrap

The target function Math.pow(…​) is now accessible through the MathFunctionStub class that could be registered in the component as below: 

@Named
JsltComponent jsltWithFunction() throws ClassNotFoundException {
    JsltComponent component = new JsltComponent();
    component.setFunctions(singleton(wrapStaticMethod("power", "org.apache.cq.example.MathFunctionStub", "pow")));

2.42.3.1. Quarkus Kafka Dev Services
Copia collegamento

Camel Quarkus Kafka can take advantage of Quarkus Kafka Dev services to simplify development and testing with a local containerized Kafka broker.

Kafka Dev Services is enabled by default in dev & test mode. The Camel Kafka component is automatically configured so that the brokers component option is set to point at the local containerized Kafka broker. Meaning that there’s no need to configure this option yourself.

This functionality can be disabled with the configuration property quarkus.kafka.devservices.enabled=false.

This extension allows to pre-load a set of Kamelets at build time using the quarkus.camel.kamelet.identifiers property.

2.43.3.2. Using the Kamelet Catalog
Copia collegamento

A set of pre-made Kamelets can be found on the /camel-kamelets/latest[Kamelet Catalog]. To use the Kamelet from the catalog you need to copy their yaml definition (that you can find in the camel-kamelet repo) on your project in the classpath. Alternatively you can add the camel-kamelets-catalog artifact to your pom.xml: 

<dependency>
    <groupId>org.apache.camel.kamelets</groupId>
    <artifactId>camel-kamelets-catalog</artifactId>
</dependency>
Copy to Clipboard Toggle word wrap

This artifact add all the kamelets available in the catalog to your Camel Quarkus application for build time processing. If you include it with the scope provided the artifact should not be part of the runtime classpath, but at build time, all the kamelets listed via quarkus.camel.kamelet.identifiers property should be preloaded.

2.44.2. Additional Camel Quarkus configuration
Copia collegamento

Important

In this release of Camel Extensions for Quarkus, the camel-quarkus-kubernetes extension is only supported when used with the camel-quarkus-master extension as a cluster service. Additionally, in order for the camel-quarkus-kubernetes extension to be supported, you must explicitly add a dependency on the quarkus-openshift-client extension in your application.

2.44.2.1. Automatic registration of a Kubernetes Client instance
Copia collegamento

The extension automatically registers a Kubernetes Client bean named kubernetesClient. You can reference the bean in your routes like this: 

from("direct:pods")
    .to("kubernetes-pods:///?kubernetesClient=#kubernetesClient&operation=listPods")
Copy to Clipboard Toggle word wrap

By default the client is configured from the local kubeconfig file. You can customize the client configuration via properties within application.properties: 

quarkus.kubernetes-client.master-url=https://my.k8s.host
quarkus.kubernetes-client.namespace=my-namespace
Copy to Clipboard Toggle word wrap

The full set of configuration options are documented in the Quarkus Kubernetes Client guide.

When the same route is deployed on multiple pods, it could be interesting to use this extension in conjunction with the Master one. In such a setup, a single consumer will be active at a time across the whole camel master namespace.

For instance, having the route below deployed on multiple pods: 

from("master:ns:timer:test?period=100").log("Timer invoked on a single pod at a time");
Copy to Clipboard Toggle word wrap

It’s possible to enable the kubernetes cluster service with a property like below: 

quarkus.camel.cluster.kubernetes.enabled = true
Copy to Clipboard Toggle word wrap

As a result, a single consumer will be active across the ns camel master namespace. It means that, at a given time, only a single timer will generate exchanges across the whole cluster. In other words, messages will be logged every 100ms on a single pod at a time.

The kubernetes cluster service could further be tuned by tweaking quarkus.camel.cluster.kubernetes.* properties.

To use camel-mock capabilities in tests it is required to get access to MockEndpoint instances.

CDI injection could be used for accessing instances (see Quarkus documentation). You can inject camelContext into test using @Inject annotation. Camel context can be then used for obtaining mock endpoints. See the following example: 

import javax.inject.Inject;

import org.apache.camel.CamelContext;
import org.apache.camel.ProducerTemplate;
import org.apache.camel.component.mock.MockEndpoint;
import org.junit.jupiter.api.Test;

import io.quarkus.test.junit.QuarkusTest;

@QuarkusTest
public class MockJvmTest {

    @Inject
    CamelContext camelContext;

    @Inject
    ProducerTemplate producerTemplate;

    @Test
    public void test() throws InterruptedException {

        producerTemplate.sendBody("direct:start", "Hello World");

        MockEndpoint mockEndpoint = camelContext.getEndpoint("mock:result", MockEndpoint.class);
        mockEndpoint.expectedBodiesReceived("Hello World");

        mockEndpoint.assertIsSatisfied();

2.55.3. Usage
Copia collegamento

You can use this extension to expose REST DSL services to Quarkus OpenAPI. With quarkus-smallrye-openapi, you can access them by /q/openapi?format=json.

Refer to the Quarkus OpenAPI guide for further information.

This is an experimental feature. You can enable it by 

quarkus.camel.openapi.expose.enabled=true
Copy to Clipboard Toggle word wrap
Warning

It’s the user’s responsibility to use @RegisterForReflection to register all model classes for reflection.

It doesn’t support the rest services used in org.apache.camel.builder.LambdaRouteBuilder right now. Also, it can not use CDI injection in the RouteBuilder configure() since we get the rest definitions at build time while CDI is unavailable.

2.55.4. Camel Quarkus limitations
Copia collegamento

The apiContextIdListing configuration option is not supported. Since multiple CamelContext`s are not supported and Quarkus applications run standalone, there is no scenario where attempting to resolve OpenApi specifications for a specific `CamelContext would be useful. It also introduces some additional overhead of requiring JMX (which is not supported in native mode) & additional Camel Quarkus extensions for processing XML.

2.56.3. Usage
Copia collegamento

The extension automatically creates a Camel OpenTelemetryTracer and binds it to the Camel registry.

In order to send the captured traces to a tracing system, you need to configure some properties within application.properties like those below. 

# Identifier for the origin of spans created by the application
quarkus.application.name=my-camel-application

# For OTLP
quarkus.opentelemetry.tracer.exporter.otlp.endpoint=http://localhost:4317

# For Jaeger
quarkus.opentelemetry.tracer.exporter.jaeger.endpoint=http://localhost:14250
Copy to Clipboard Toggle word wrap

Note that you must add a dependency to the OpenTelemetry exporter that you want to work with.

Refer to the Quarkus OpenTelemetry guide for a full list of configuration options.

Route endpoints can be excluded from tracing by configuring a property named quarkus.camel.opentelemetry.exclude-patterns in application.properties. For example: 

# Exclude all direct & netty-http endpoints from tracing
quarkus.camel.opentelemetry.exclude-patterns=direct:*,netty-http:*

Expand
Configuration propertyTypeDefault

lock quarkus.camel.opentelemetry.encoding

Sets whether header names need to be encoded. Can be useful in situations where OpenTelemetry propagators potentially set header name values in formats that are not compatible with the target system. E.g for JMS where the specification mandates header names are valid Java identifiers.

boolean

false

lock quarkus.camel.opentelemetry.exclude-patterns

Sets whether to disable tracing for endpoint URIs that match the given patterns. The pattern can take the following forms:

1. An exact match on the endpoint URI. E.g platform-http:/some/path

2. A wildcard match. E.g platform-http:*

3. A regular expression matching the endpoint URI. E.g platform-http:/prefix/.*

2.59.3.4. Securing platform-http endpoints
Copia collegamento

Quarkus provides a variety of security and authentication mechanisms which can be used to secure platform-http endpoints. Refer to the Quarkus Security documentation for further details.

Within a route, it is possible to obtain the authenticated user and its associated SecurityIdentity and Principal: 

from("platform-http:/secure")
    .process(e -> {
        Message message = e.getMessage();
        QuarkusHttpUser user = message.getHeader(VertxPlatformHttpConstants.AUTHENTICATED_USER, QuarkusHttpUser.class);
        SecurityIdentity securityIdentity = user.getSecurityIdentity();
        Principal principal = securityIdentity.getPrincipal();
        // Do something useful with SecurityIdentity / Principal. E.g check user roles etc.
    });

2.62.3. Usage
Copia collegamento

CDI producer methods can be harnessed to bind endpoints to the Camel registry, so that they can be resolved using the ref URI scheme in Camel routes.

For example, to produce endpoint beans: 

@ApplicationScoped
public class MyEndpointProducers {
    @Inject
    CamelContext context;

    @Singleton
    @Produces
    @Named("endpoint1")
    public Endpoint directStart() {
        return context.getEndpoint("direct:start");
    }

    @Singleton
    @Produces
    @Named("endpoint2")
    public Endpoint logEnd() {
        return context.getEndpoint("log:end");
    }
}
Copy to Clipboard Toggle word wrap

Use ref: to refer to the names of the CDI beans that were bound to the Camel registry: 

public class MyRefRoutes extends RouteBuilder {
    @Override
    public void configure() {
        // direct:start -> log:end
        from("ref:endpoint1")

2.63.3. Additional Camel Quarkus configuration
Copia collegamento

This extension depends on the Platform HTTP extension and configures it as the component that provides the REST transport.

2.63.3.1. Path parameters containing special characters with platform-http
Copia collegamento

When using the platform-http REST transport, some characters are not allowed within path parameter names. This includes the '-' and '$' characters.

In order to make the below example REST /dashed/param route work correctly, a system property is required io.vertx.web.route.param.extended-pattern=true. 

import org.apache.camel.builder.RouteBuilder;

public class CamelRoute extends RouteBuilder {

    @Override
    public void configure() {
        rest("/api")
            // Dash '-' is not allowed by default
            .get("/dashed/param/{my-param}")
            .to("direct:greet")

            // The non-dashed path parameter works by default
            .get("/undashed/param/{myParam}")
            .to("direct:greet");

            from("direct:greet")
                .setBody(constant("Hello World"));
    }
}

There is some more background to this in the Vert.x Web documentation.

2.63.3.2. Configuring alternate REST transport providers
Copia collegamento

To use another REST transport provider, such as netty-http or servlet, you need to add the respective extension as a dependency to your project and set the provider in your RouteBuilder. E.g. for servlet, you’d have to add the org.apache.camel.quarkus:camel-quarkus-servlet dependency and the set the provider as follows: 

import org.apache.camel.builder.RouteBuilder;

public class CamelRoute extends RouteBuilder {

    @Override
    public void configure() {
        restConfiguration()
                .component("servlet");
        ...
    }

2.64.3. Usage
Copia collegamento

2.64.3.1. Required Dependencies
Copia collegamento

A RestProducerFactory implementation must be available when using the rest-openapi extension. The currently known extensions are:

  • camel-quarkus-http

Maven users will need to add one of these dependencies to their pom.xml, for example: 

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-http</artifactId>
</dependency>
Copy to Clipboard Toggle word wrap

Depending on which mechanism is used to load the OpenApi specification, additional dependencies may be required. When using the file resource locator, the org.apache.camel.quarkus:camel-quarkus-file extension must be added as a project dependency. When using ref or bean to load the specification, not only must the org.apache.camel.quarkus:camel-quarkus-bean dependency be added, but the bean itself must be annotated with @RegisterForReflection.

When using the classpath resource locator with native code, the path to the OpenAPI specification must be specified in the quarkus.native.resources.includes property of the application.properties file. For example: 

quarkus.native.resources.includes=openapi.json

2.74.3. Usage
Copia collegamento

2.74.3.1. Custom body as domain object in the native mode
Copia collegamento

When using a custom object as message body and referencing its properties in the template in the native mode, all the classes need to be registered for reflection (see the documentation).

Example: 

@RegisterForReflection
public interface CustomBody {
}

2.74.4. allowContextMapAll option in native mode
Copia collegamento

The allowContextMapAll option is not supported in native mode as it requires reflective access to security sensitive camel core classes such as CamelContext & Exchange. This is considered a security risk and thus access to the feature is not provided by default.

2.74.5. Additional Camel Quarkus configuration
Copia collegamento

This component typically loads Velocity templates from classpath. To make it work also in native mode, you need to explicitly embed the templates in the native executable by using the quarkus.native.resources.includes property.

For instance, the route below would load the Velocity template from a classpath resource named template/simple.vm: 

from("direct:start").to("velocity://template/simple.vm");
Copy to Clipboard Toggle word wrap

To include this (an possibly other templates stored in .vm files in the template directory) in the native image, you would have to add something like the following to your application.properties file: 

quarkus.native.resources.includes = template/*.vm

2.75.3. Additional Camel Quarkus configuration
Copia collegamento

This component is able to load xpath expressions from classpath resources. To make it work also in native mode, you need to explicitly embed the expression files in the native executable by using the quarkus.native.resources.includes property.

For instance, the route below would load an XPath expression from a classpath resource named myxpath.txt: 

from("direct:start").transform().xpath("resource:classpath:myxpath.txt");
Copy to Clipboard Toggle word wrap

To include this (an possibly other expressions stored in .txt files) in the native image, you would have to add something like the following to your application.properties file: 

quarkus.native.resources.includes = *.txt

2.76.3. Additional Camel Quarkus configuration
Copia collegamento

This component is able to load XQuery definitions from classpath. To make it work also in native mode, you need to explicitly embed the queries in the native executable by using the quarkus.native.resources.includes property.

For instance, the two routes below load an XQuery script from two classpath resources named myxquery.txt and another-xquery.txt respectively: 

from("direct:start").transform().xquery("resource:classpath:myxquery.txt", String.class);
from("direct:start").to("xquery:another-xquery.txt");
Copy to Clipboard Toggle word wrap

To include these (an possibly other queries stored in .txt files) in the native image, you would have to add something like the following to your application.properties file: 

quarkus.native.resources.includes = *.txt

2.77. XSLT

    <artifactId>camel-quarkus-xslt</artifactId>
</dependency>

2.77.3. Additional Camel Quarkus configuration
Copia collegamento

To optimize XSLT processing, the extension needs to know the locations of the XSLT templates at build time. The XSLT source URIs have to be passed via the quarkus.camel.xslt.sources property. Multiple URIs can be separated by comma. 

quarkus.camel.xslt.sources = transform.xsl, classpath:path/to/my/file.xsl
Copy to Clipboard Toggle word wrap

Scheme-less URIs are interpreted as classpath: URIs.

Only classpath: URIs are supported on Quarkus native mode. file:, http: and other kinds of URIs can be used on JVM mode only.

<xsl:include> and <xsl:messaging> XSLT elements are also supported in JVM mode only right now.

If aggregate DSL is used, XsltSaxonAggregationStrategy has to be used such as 

from("file:src/test/resources?noop=true&sortBy=file:name&antInclude=*.xml")
   .routeId("aggregate").noAutoStartup()
   .aggregate(new XsltSaxonAggregationStrategy("xslt/aggregate.xsl"))
   .constant(true)
   .completionFromBatchConsumer()
   .log("after aggregate body: ${body}")
   .to("mock:transformed");
Copy to Clipboard Toggle word wrap

Also, it’s only supported on JVM mode.

2.77.3.1. Configuration
Copia collegamento

TransformerFactory features can be configured using following property: 

quarkus.camel.xslt.features."http\://javax.xml.XMLConstants/feature/secure-processing"=false
Copy to Clipboard Toggle word wrap

2.77.3.2. Extension functions support
Copia collegamento

Xalan’s extension functions do work properly only when:

  1. Secure-processing is disabled
  2. Functions are defined in a separate jar
  3. Functions are augmented during native build phase. For example, they can be registered for reflection: 
@RegisterForReflection(targets = { my.Functions.class })
public class FunctionsConfiguration {
}
Copy to Clipboard Toggle word wrap
Note

The content of the XSLT source URIs is parsed and compiled into Java classes at build time. These Java classes are the only source of XSLT information at runtime. The XSLT source files may not be included in the application archive at all.
