在JBoss7上的JAX-RS资源中注入EJB

标签: jboss jax-rs ejb-3.1

我想知道为什么ejb注入JAX-RS资源(JBoss7上的RestEasy)无效。 EJB不是战争的一部分,而是它自己的EJB jar,但我认为这不应该是问题。我被迫做了ctx.lookups“解决方法”,这并不漂亮。我是否遗漏了某些东西,或者真的不支持这样注入EJB?以下示例不适用于JBoss,但适用于Glassfish(遗憾的是我必须在JBoss上运行我的应用程序)

Path("x")
@RequestScoped
public class UserResource {

    @Inject // CDI not working too
    private Service service1;
    @EJB
    private Service service2;

    private Service service3;


    @GET
    @Path("y")
    public Response authenticate(@Context HttpHeaders headers) {
         System.out.println("null == " + service1);
         System.out.println("null == " + service2);

         service3 = annoyingLookup(Service.class);
         System.out.println("null != " + service3);
    }

    private <T> T annoyingLookup(Class<T> clazz) {
       ...
       ctx.lookup("java:app/module/" + classzz.getSimpleName());
    }

以下内容对我有用。

RESTEasy根上下文:

package com.foo.rest;

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

@ApplicationPath("/rest")
public class RestServiceLocator extends Application {

}

STLS bean:

package com.foo.rest;

import javax.ejb.EJB;
import javax.ejb.Local;
import javax.ejb.LocalBean;
import javax.ejb.Stateless;
import javax.ws.rs.Path;
import javax.ws.rs.core.Response;
import javax.ws.rs.GET;
import javax.ws.rs.Produces;

@Path("/foo")
@Stateless
@LocalBean //Note: @Local(FooResource.class) does not let RESTEasy to load EJB!
public class FooResourceBean implements FooResource {

    @EJB 
    private FooResourceBean h; // Works!

    /**
     * http://localhost:8080/webapp/rest/foo/baa
     *  
     */
    @GET
    @Path("/baa")
    @Produces("application/json")
    @Override
    public Response baa() {

        String json = "{ \"baa\" : [ " +
                      "             { \"icon\":\"source1.png\" , \"description\":\"Source 1\" }, " +
                      "             { \"icon\":\"source2.png\" , \"description\":\"Source 2\" }, " +
                      "             { \"icon\":\"source3.png\" , \"description\":\"Source 3\" } " +
                      "          ]}\";";

        return Response.ok(json).build();
    }

}

添加

@Stateless

到JAX-RS资源

@Path("/")
@Stateless
public class MainMain
{    

    @EJB(mappedName = "java:global/optima-wsi/OptimaConfigurator!com.sistemaits.optima.configurator.IOptimaConfigurator")
    IOptimaConfigurator configurator;
