RESTEasy Releases

By James R. Perkins | April 19, 2022

It is time for the next quarterly releases of RESTEasy. With these releases I’m very pleased to announce the release of RESTEasy 6.1.0.Beta1. This is the first release which implements Jakarta RESTful Web Services 3.1.

Along with the 6.1.0.Beta1 release, there have been three bug fix releases; 6.0.1.Final, 5.0.3.Final and 4.7.6.Final.

RESTEasy 6.1.0

The Jakarta RESTful Web Services 3.1 specification is targeted for Jakarta EE 10. It also includes a new SeBootstrap API for publishing an application on Java SE. You can see a full list of the specification changes for 3.1 here.

While we wait for the Jakarta REST 3.1.0 artifact to be deployed to Maven Central, there is a temporary fork of the API which can be used. You need to enable the JBoss Nexus Repository to use this dependency. Below are some example POM snippets.

API Dependency

<dependency>
    <groupId>jakarta.ws.rs</groupId>
    <artifactId>jakarta.ws.rs-api</artifactId>
    <version>3.1.0.RC1-jbossorg-1</version>
</dependency>

RESTEasy CDI

The RESTEasy CDI extension has been updated to allow injection of certain types. You can use @Inject on the following types for instance fields:

jakarta.ws.rs.client.Client
jakarta.ws.rs.container.ResourceContext
jakarta.ws.rs.core.Application
jakarta.ws.rs.core.Configuration
jakarta.ws.rs.core.HttpHeaders
jakarta.ws.rs.core.Request
jakarta.ws.rs.core.Response
jakarta.ws.rs.core.SecurityContext
jakarta.ws.rs.core.UriInfo
jakarta.ws.rs.ext.Providers
jakarta.ws.rs.sse.Sse

Example `SeBootstrap` Usage

In RESTEasy the SeBootstrap API requires the following dependencies.

<depenedencies>
    <dependency>
        <groupId>jakarta.ws.rs</groupId>
        <artifactId>jakarta.ws.rs-api</artifactId>
        <version>3.1.0.RC1-jbossorg-1</version>
    </dependency>
    <dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-core</artifactId>
        <version>6.1.0.Alpha1</version>
    </dependency>
    <dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-undertow</artifactId>
        <version>6.1.0.Alpha1</version>
    </dependency>
</depenedencies>

The resteasy-undertow server adaptor is the default adaptor and is what RESTEasy uses for testing with the TCK.

        SeBootstrap.Instance instance = SeBootstrap.start(new Application() {
            @Override
            public Set<Class<?>> getClasses() {
                return Collections.singleton(GreetingResource.class);
            }
        }).toCompletableFuture().get();

        try (Client client = ClientBuilder.newClient()) {
            final Response response = client.target(instance.configuration().baseUriBuilder().path("greet/World"))
                    .request().get();
            System.out.println(response.readEntity(String.class));
        }
        instance.stop().toCompletableFuture().get();
    }

    @Path("/greet")
    public static class GreetingResource {

        @GET
        @Produces(MediaType.TEXT_PLAIN)
        @Path("{name}")
        public Response greet(@PathParam("name") final String name) {
            return Response.ok(String.format("Hello %s!", name)).build();
        }
    }
