从公共IP访问自己的私有IP

我正在开发一个服务器客户端应用程序。 服务器一个本质上是一个嵌入灰色服务器暴露REST服务，客户端应该是一个Android应用程序。 为了暴露REST服务我正在使用spring.My资源就是这样：

@Component
@Path("/info")
public class InfoResource {

private static Logger logger = Logger.getLogger(InfoResource.class);

@SuppressWarnings("unchecked")
@Path("/")
@GET
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Response info(){

    Response response = null;

    JSONObject jsonObject = new JSONObject();

    jsonObject.put("Server Name", "Woghetto Server");
    jsonObject.put("Date", new Date());

    response = Response.ok(jsonObject).build();

    logger.debug(jsonObject.toJSONString());

    response = Response.ok(jsonObject).build();

    return response;
}

服务器不适合部署在外部域上，因此应该可以从公共IP访问它。 我正在使用jTCPfwd-lite-0.5将我的私有IP隧道连接到我的公共IP @端口80。 出于测试目的，我需要从部署服务器的同一台笔记本电脑访问公开的资源。 基本上，我想使用我的公共IP作为目标，从一个泽西2客户端到达我的服务器，部署在localhost：8080。我尝试了几种方法，但主要是我构建客户端，如下所示：

Response response = client.target("http://" + targetAddress + ":80/info")  
.request().get();

我得到的是这个stacktrace

或者像这样

Response response = client.target(basicURI)
            .request().get();

获得

其中

basicURI = UriBuilder.fromUri(targetAddress)
            .port(80) .path("/info").build();

和targetAddress是我的公共IP，所以像123.456.789.11

通常应该从我的路由器外部到达服务器，所以我想它应该可以工作但是，正如我之前所说，我需要测试应用程序，我想从JUnit测试用例中进行。 我想我也可以从Android应用程序测试它，但对我来说似乎既不是一个好的练习也不是一个快速的练习。

任何帮助表示赞赏!!

答案 0 :(得分：0)

我发现您的应用有几个问题：

  1. InfoResource未在Configuration中注册，因此/ info永远不可用。

  2. 在InfoResourceTest中，您不注册servlet：

    WebContainer.registerServlet(webappContext);

  3. InfoResource返回JSON对象，所以可能你想把它声明为：

    @Produces(MediaType.APPLICATION_JSON)

  4. 一旦应用了上述所有更改，应用程序就可以直接在localhost：8082上访问，但仍然不能通过转发器服务器访问，因此该部分也应该有问题。
