Making open source more inclusive

Red Hat is committed to replacing problematic language in our code, documentation, and web properties. We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see our CTO Chris Wright’s message.

Chapter 1. Extensions overview

1.1. Support level definitions
Link kopieren

New features, services, and components go through a number of support levels before inclusion in Camel Quarkus as fully supported for production use. This is to ensure the right balance between providing the enterprise stability expected of our offerings with the need to allow our customers and partners to experiment with new Camel Quarkus technologies while providing feedback to help guide future development activities.

Table 1.1. Camel Extensions for Quarkus support levels
Type	Description
Community Support	As part of Red Hat’s commitment to upstream first, integration of new extensions into our Camel Quarkus distribution begins in the upstream community. While these Camel Quarkus extensions have been tested and documented upstream, we have not reviewed the maturity of these extensions and they may not be formally supported by Red Hat in future product releases.
Technology Preview	Technology Preview features provide early access to upcoming product innovations, enabling you to test functionality and provide feedback during the development process. However, these features are not fully supported under Red Hat Subscription Level Agreements, may not be functionally complete, and are not intended for production use. As Red Hat considers making future iterations of Technology Preview features generally available, we will attempt to resolve any issues that customers experience when using these features. Note Technology Preview support is limited to JVM mode in this release.
Production Support	Production Support extensions are shipped in a formal Red Hat release and are fully supported. There are no documentation gaps and extensions have been tested on all supported configurations.

1.2. Supported extensions

2.1.3. Additional Camel Quarkus configuration
Link kopieren

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 via the @BuildTimeAvroDataFormat annotation.

For instance below, in the first step the user.avsc schema resource is parsed at build time. In the second step, an AvroDataFormat instance using the previously parsed schema is injected in the buildTimeAvroDataFormat field at runtime. At the end of the day, the injected data format is used from the configure() method in order to marshal an incoming message.

@BuildTimeAvroDataFormat("user.avsc")
AvroDataFormat buildTimeAvroDataFormat;

@Override
public void configure() {
  from("direct:marshalUsingBuildTimeAvroDataFormat").marshal(buildTimeAvroDataFormat);
}

@BuildTimeAvroDataFormat("user.avsc")
AvroDataFormat buildTimeAvroDataFormat;

@Override
public void configure() {
  from("direct:marshalUsingBuildTimeAvroDataFormat").marshal(buildTimeAvroDataFormat);

2.10.4.1. Simple language
Link kopieren

2.10.4.1.1. Using the OGNL notation
Link kopieren

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

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

---
simple("${body.address}")
---

---
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.

2.10.4.1.2. Using dynamic type resolution in native mode
Link kopieren

When dynamically resolving a type from simple expressions like ${mandatoryBodyAs(TYPE)}, ${type:package.Enum.CONSTANT} or ${body} is TYPE, it may be needed to register some classes for reflection manually.

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

---
simple("${body} is 'java.nio.ByteBuffer'")
---

---
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.

2.10.4.1.3. Using the simple language with classpath resources in native mode
Link kopieren

Beyond standard usages, a trick is needed when using the simple language with classpath resources in native mode. In such a situation, one needs to explicitly embed the resources in the native executable by specifying the include-patterns option.

For instance, the route below would load a simple script from a classpath resource named mysimple.txt:

from("direct:start").transform().simple("resource:classpath:mysimple.txt");

from("direct:start").transform().simple("resource:classpath:mysimple.txt");

Copy to Clipboard

Toggle word wrap

In order to work in native mode the include-patterns configuration should be set. For instance, in the application.properties file as below :

quarkus.camel.native.resources.include-patterns = *.txt

quarkus.camel.native.resources.include-patterns = *.txt

Configuration property	Type	Default
`quarkus.camel.bootstrap.enabled` When set to true, the `CamelRuntime` will be started automatically.	`boolean`	`true`
`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`
`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`
`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`
`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.

Example values: `META-INF/services/org/apache/camel/foo/,META-INF/services/org/apache/camel/foo/*/bar`	`string`
`quarkus.camel.runtime-catalog.components` If `true` the Runtime Camel Catalog embedded in the application will contain JSON schemas of Camel components available in the application; otherwise component JSON schemas will not be available in the Runtime Camel Catalog and any attempt to access those will result in a RuntimeException. Setting this to `false` helps to reduce the size of the native image. In JVM mode, there is no real benefit of setting this flag to `false` except for making the behavior consistent with native mode.	`boolean`	`true`
`quarkus.camel.runtime-catalog.languages` If `true` the Runtime Camel Catalog embedded in the application will contain JSON schemas of Camel languages available in the application; otherwise language JSON schemas will not be available in the Runtime Camel Catalog and any attempt to access those will result in a RuntimeException. Setting this to `false` helps to reduce the size of the native image. In JVM mode, there is no real benefit of setting this flag to `false` except for making the behavior consistent with native mode.	`boolean`	`true`
`quarkus.camel.runtime-catalog.dataformats` If `true` the Runtime Camel Catalog embedded in the application will contain JSON schemas of Camel data formats available in the application; otherwise data format JSON schemas will not be available in the Runtime Camel Catalog and any attempt to access those will result in a RuntimeException. Setting this to `false` helps to reduce the size of the native image. In JVM mode, there is no real benefit of setting this flag to `false` except for making the behavior consistent with native mode.	`boolean`	`true`
`quarkus.camel.runtime-catalog-models` If `true` the Runtime Camel Catalog embedded in the application will contain JSON schemas of Camel EIP models available in the application; otherwise EIP model JSON schemas will not be available in the Runtime Camel Catalog and any attempt to access those will result in a RuntimeException. Setting this to `false` helps to reduce the size of the native image.

`quarkus.camel.routes-discovery.enabled` Enable automatic discovery of routes during static initialization.	`boolean`	`true`
`quarkus.camel.routes-discovery.exclude-patterns` Used for exclusive filtering scanning of RouteBuilder classes. The exclusive filtering takes precedence over inclusive filtering. The pattern is using Ant-path style pattern. Multiple patterns can be specified separated by comma. For example to exclude all classes starting with Bar use: */Bar To exclude all routes form a specific package use: com/mycompany/bar/* To exclude all routes form a specific package and its sub-packages use double wildcards: com/mycompany/bar/** And to exclude all routes from two specific packages use: com/mycompany/bar/,com/mycompany/stuff/	`string`
`quarkus.camel.routes-discovery.include-patterns` Used for inclusive filtering scanning of RouteBuilder classes. The exclusive filtering takes precedence over inclusive filtering. The pattern is using Ant-path style pattern. Multiple patterns can be specified separated by comma. For example to include all classes starting with Foo use: */Foo To include all routes form a specific package use: com/mycompany/foo/* To include all routes form a specific package and its sub-packages use double wildcards: com/mycompany/foo/** And to include all routes from two specific packages use: com/mycompany/foo/,com/mycompany/stuff/	`string`
`quarkus.camel.native.resources.exclude-patterns` A comma separated list of Ant-path style patterns to match resources that should be excluded from the native executable. By default, resources not selected by quarkus itself are ignored. Then, inclusion of additional resources could be triggered with `includePatterns`. When the inclusion patterns is too large, eviction of previously selected resources could be triggered with `excludePatterns`.	`string`
`quarkus.camel.native.resources.include-patterns` A comma separated list of Ant-path style patterns to match resources that should be included in the native executable. By default, resources not selected by quarkus itself are ignored. Then, inclusion of additional resources could be triggered with `includePatterns`. When the inclusion patterns is too large, eviction of previously selected resources could be triggered with `excludePatterns`.	`string`
`quarkus.camel.native.reflection.exclude-patterns` A comma separated list of Ant-path style patterns to match class names that should be excluded from registering 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 `$`. This option narrows down the set selected by `include-patterns`. By default, no classes are excluded. This option cannot be used to unregister classes which have been registered internally by Quarkus extensions.	`string`
`quarkus.camel.native.reflection.include-patterns` A comma separated list of Ant-path style patterns to match class names that should be registered for reflection. Use the class name format as returned by the `java.lang.Class.getName()` method: package segments delimited by period `.` and inner classes by dollar sign `$`. 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, the artifacts containing the selected classes must either contain a Jandex index (`META-INF/jandex.idx`) or they must be 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.	`string`
`quarkus.camel.csimple.on-build-time-analysis-failure` What to do if it is not possible to extract CSimple expressions from a route definition at build time.	`org.apache.camel.quarkus.core.CamelConfig.FailureRemedy`	`warn`
`quarkus.camel.main.enabled` If `true` all `camel-main` features are enabled; otherwise no `camel-main` features are enabled.	`boolean`	`true`
`quarkus.camel.main.shutdown.timeout` A timeout (with millisecond precision) to wait for `CamelMain#stop()` to finish	`java.time.Duration`	`PT3S`
`quarkus.camel.main.arguments.on-unknown` The action to take when `CamelMain` encounters an unknown argument. fail - Prints the `CamelMain` usage statement and throws a `RuntimeException` ignore - Suppresses any warnings and the application startup proceeds as normal warn - Prints the `CamelMain` usage statement but allows the application startup to proceed as normal	`org.apache.camel.quarkus.core.CamelConfig.FailureRemedy`	`warn`

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();
    }
}

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();

Link kopieren

The extension leverages the Quarkus MongoDB Client extension. The Mongo client can be configured via the Quarkus MongoDB Client configuration options.

The Camel Quarkus MongoDB extension automatically registers a MongoDB client bean named camelMongoClient. This can be referenced in the mongodb endpoint URI connectionBean path parameter. For example:

from("direct:start")
.to("mongodb:camelMongoClient?database=myDb&collection=myCollection&operation=findAll")

from("direct:start")
.to("mongodb:camelMongoClient?database=myDb&collection=myCollection&operation=findAll")

If your application needs to work with multiple MongoDB servers, you can create a "named" client and reference in your route by injecting a client and the related configuration as explained in the Quarkus MongoDB extension client injection. For example:

//application.properties
quarkus.mongodb.mongoClient1.connection-string = mongodb://root:example@localhost:27017/

//application.properties
quarkus.mongodb.mongoClient1.connection-string = mongodb://root:example@localhost:27017/

2.35.3.2. Using platform-http via Camel REST DSL
Link kopieren

To be able to use Camel REST DSL with the platform-http component, add camel-quarkus-rest in addition to camel-quarkus-platform-http to your pom.xml:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-rest</artifactId>
</dependency>

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-rest</artifactId>
</dependency>

Copy to Clipboard

Toggle word wrap

Then you can use the Camel REST DSL:

rest()
    .get("/my-get-endpoint")
        .route()
        .setBody(constant("Hello from /my-get-endpoint"))
        .endRest()
    .post("/my-post-endpoint")
        .route()
        .setBody(constant("Hello from /my-post-endpoint"))
        .endRest();

rest()
    .get("/my-get-endpoint")
        .route()
        .setBody(constant("Hello from /my-get-endpoint"))
        .endRest()
    .post("/my-post-endpoint")
        .route()
        .setBody(constant("Hello from /my-post-endpoint"))
        .endRest();

2.35.3.3. Handling multipart/form-data file uploads
Link kopieren

If you want Camel Quarkus to attach uploaded files to Camel messages for you, you need to add the following optional dependency to your pom.xml:

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-attachments</artifactId>
</dependency>

<dependency>
    <groupId>org.apache.camel.quarkus</groupId>
    <artifactId>camel-quarkus-attachments</artifactId>
</dependency>

Copy to Clipboard

Toggle word wrap

You can restrict the uploads to certain file extensions by white listing them:

from("platform-http:/upload/multipart?fileNameExtWhitelist=html,txt&httpMethodRestrict=POST")
    .to("log:multipart")
    .process(e -> {
        final AttachmentMessage am = e.getMessage(AttachmentMessage.class);
        if (am.hasAttachments()) {
            am.getAttachments().forEach((fileName, dataHandler) -> {
                try (InputStream in = dataHandler.getInputStream()) {
                    // do something with the input stream
                } catch (IOException ioe) {
                    throw new RuntimeException(ioe);
                }
            });
        }
    });

from("platform-http:/upload/multipart?fileNameExtWhitelist=html,txt&httpMethodRestrict=POST")
    .to("log:multipart")
    .process(e -> {
        final AttachmentMessage am = e.getMessage(AttachmentMessage.class);
        if (am.hasAttachments()) {
            am.getAttachments().forEach((fileName, dataHandler) -> {
                try (InputStream in = dataHandler.getInputStream()) {
                    // do something with the input stream
                } catch (IOException ioe) {
                    throw new RuntimeException(ioe);
                }
            });

2.36.3. Additional Camel Quarkus configuration
Link kopieren

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

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");
        ...
    }
}

import org.apache.camel.builder.RouteBuilder;

public class CamelRoute extends RouteBuilder {

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

2.38.3. Additional Camel Quarkus configuration
Link kopieren

Beyond standard usages described above, a trick is needed when using the xquery language and component with classpath resources in native mode. In such a situation, one needs to explicitly embed the resources in the native executable by specifying the include-patterns option.

For instance, the 2 routes below would load a xquery script from 2 classpath resources respectively named myxquery.txt and another-xquery.txt:

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

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

In order to work in native mode the include-patterns configuration should be set. For instance, in the application.properties file as below :

quarkus.camel.native.resources.include-patterns = *.txt

quarkus.camel.native.resources.include-patterns = *.txt
