java - ReSTLet 在处理完一个请求后停止服务器

Question

我想使用Restlet创建本地服务器。该服务器应该接收精确的一个请求(除了图标)，并且在处理该请求后它应该关闭。我不想使用 System.exit，我希望它正确关闭。

正如您在我的代码中看到的，当我假设请求得到正确处理时，我注释了该行。但我不能告诉服务器停在那里。

此时我如何告诉服务器停止等待请求？我已经成功了，但有两个问题我想解决。

• 当我在请求中停止服务器时出现异常

• 如果我在请求中停止服务器，发送到客户端的响应将不会显示

  public class Main {
  
  public static void main(String[] args){
      Server serv = null;
  
      Restlet restlet = new Restlet() {
          @Override
          public void handle(Request request, Response response) {
  
            if(!request.toString().contains("favicon")){
                System.out.println("do stuff");
                response.setEntity("Request will be handled", MediaType.TEXT_PLAIN);
                //stop server after the first request is handled. 
                //so the program should shut down here
                //if I use serv.stop() here (besides it's currently not final)
                //I'd get exceptions and the user wouldn't see the response
            }
          }
      };
  
  
  
      // Avoid conflicts with other Java containers listening on 8080!
      try {
          serv = new Server(Protocol.HTTP, 8182, restlet);
  
          serv.start();
      } catch (Exception e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
      }
  }
  
  }

我想出了一个办法。将 OnSent 事件添加到响应中，并在此处关闭服务器。

public class Main {

    private Server serv;

    public Main(){
        run();
    }

    public void run(){

            Restlet restlet = new Restlet() {
                @Override
                public void handle(Request request, Response response) {
                    response.setEntity("Request will be handled", MediaType.TEXT_PLAIN);
                  if(!request.toString().contains("favicon")){
                      System.out.println("do stuff");

                      response.setOnSent(new Uniform() {

                        @Override
                        public void handle(Request req, Response res) {

                            try {
                                serv.stop();//stop the server
                            } catch (Exception e) {
                                // TODO Auto-generated catch block
                                e.printStackTrace();
                            }
                        }
                    });

                  }
                }
            };

            // Avoid conflicts with other Java containers listening on 8080!
            try {
                serv = new Server(Protocol.HTTP, 8182, restlet);

                serv.start();
            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
    }

    public static void main(String[] args){

        new Main();

    }

}
