只有远程接口的 EJB 3.1 会话 Bean 上的 JAX-RS

Question

我可以在只有远程接口的 EJB 3.1 会话 bean 上使用 @Path 等 JAX-RS 注释吗？

这个有效：

@Path("/service")
@Stateless
public class ServiceOne {
    @POST
    @Path("/foo")
    public Response foo() {
        return Response.ok().build();
    }
}

但是，如果我添加一个远程接口...

@Remote
public interface ServiceOneRemote {
    Response foo();
}

@Path("/service")
@Stateless
public class ServiceOne implements ServiceOneRemote {
    @POST
    @Path("/foo")
    public Response foo() {
        return Response.ok().build();
    }
}

...我得到一个 NotSerializableException

从类似 Implementing RESTful views of an EJB with local interfaces 的文章中，我得到的印象是 JAX-RS 仅适用于具有本地接口的会话 bean。但是我找不到任何明确说明这是不可能的资源。

我做错了什么吗？或者这是不可能的？

顺便说一句：我是运行一个 JBoss EAP 6.4 应用程序服务器。

Answer 1

这是不可能的。在 JSR-339（RESTful Web 服务的 JavaTM API）规范中，说明如下：

JAX-RS annotations can be applied to methods in an EJB’s local interface or directly to methods in a no-interface EJB.
