如何根据后缀有条件地路由JAX-RS请求?

这就是我要做的:

@Path("/finder")
public class Finder {
  @Path("/{name}")
  public Proxy find(@PathParam("name") String name) {
    Object found = /* some object found by name */
    return new Proxy(found);
  }
}
public class Proxy {
  private Object obj;
  public Proxy(Object found) {
    this.obj = found;
  }
  @GET
  @Path("/")
  public String info() {
    return /* some meta-information about the object */
  }
  @Path("/")
  public Object passthru() {
    return this.obj;
  }
}

我正在尝试启用:

GET /finder/alpha -> Proxy.info()
GET /finder/alpha/something -> obj.something()

我走对了吗?与此同时,泽西说:
