[keycloak-user] Custom rest endpoint

Thu Sep 29 05:41:11 EDT 2016

Google didn’t help.

There was 2 things, first of all, I should return Response object (not String):

@Path("/{action}")
@GET
public Response get(@PathParam("action") String action) {
    String json = "{\"test\" : \"" + action + "\"}";
    return Response.ok(json, MediaType.APPLICATION_JSON_TYPE).build();
}

Second thing is that you need to add dependency to module (during install) because you will get ClassNotFoundException:

--dependencies=org.keycloak.keycloak-core,org.keycloak.keycloak-server-spi,org.keycloak.keycloak-services,javax.servlet.api,org.jboss.resteasy.resteasy-jaxrs,javax.ws.rs.api"

I hope this will help other people.

Also, try Googling "RESTEASY003815: Subresource for target class has no jax-rs annotations". I'm sure others has had that issue with RestEasy/JAX-RS before.

I can’t make REST endpoint work, I’m using exactly code supplied in example, I tried also to check how standard endpoints in keycloak code are created, all looks similar:

/**
 * @author <a href="mailto:sthorger at redhat.com<mailto:sthorger at redhat.com>">Stian Thorgersen</a>
 */
public class HelloResourceProvider implements RealmResourceProvider {

    private KeycloakSession session;

    public HelloResourceProvider(KeycloakSession session) {
        this.session = session;
    }

    @GET
    @Produces(MediaType.TEXT_HTML)
    @Path("/{action}")
    public String get(@PathParam("action") String action) {
        //String requestUri = session.getContext().getUri().getRequestUri().toString();

        String title = "APP_REQUEST";
        if (action.equals("auth")) {
            title = "AUTH_RESPONSE";
        } else if (action.equals("logout")) {
            title = "LOGOUT_REQUEST";
        }

        StringBuilder sb = new StringBuilder();
        sb.append("<html><head><title>" + title + "</title></head><body>");
        UriBuilder base = UriBuilder.fromUri("http://localhost:8180/auth");
        sb.append("<a href=\"" + RealmsResource.accountUrl(base).build("test").toString() + "\" id=\"account\">account</a>");

        sb.append("</body></html>");
        return sb.toString();
    }

    @Override
    public Object getResource() {
        return this;
    }

    @Override
    public void close() {
    }

}

But I’m still getting:

RESTEASY003815: Subresource for target class has no jax-rs annotations.: nl.vi.keycloak.providers.rest.HelloResourceProvider

Can you please help me? Thanks

Kind Regards,
