泽西URL转发 [英] Jersey URL forwarding

问题描述

在Jersey REST方法中，我想转发到另一个网站。我怎样才能实现呢？

Inside a Jersey REST method I would like to forward to an another website. How can I achieve that?

@Path("/")
public class News {

    @GET
    @Produces(MediaType.TEXT_HTML)
    @Path("go/{news_id}")
    public String getForwardNews(
        @PathParam("news_id") String id) throws Exception {

        //how can I make here a forward to "http://somesite.com/news/id" (not redirect)?

        return "";
    }
}

编辑：

我正在获取尝试执行此类操作时，类$ Proxy78 的代理范围内没有线程本地值这个：

I'm getting the No thread local value in scope for proxy of class $Proxy78 error when trying to do something like this:

@Context
HttpServletRequest request;
@Context
HttpServletResponse response;
@Context
ServletContext context;

...

RequestDispatcher dispatcher =  context.getRequestDispatcher("url");
dispatcher.forward(request, response);

推荐答案

public Response foo()
{
    URI uri = UriBuilder.fromUri(<ur url> ).build();
    return Response.seeOther( uri ).build();
}

我在我的应用程序中使用了上面的代码并且它有效。

I used above code in my application and it works.
