Question

我想使用Restlet来创建本地服务器。此服务器应该接收exaclty一个请求（除了favicon），并且在处理该请求之后它应该关闭。我不想使用System.exit，我希望它能够正常关闭。

正如您在我的代码中所看到的，当我假设请求得到正确处理时，我对该行进行了评论。但我无法告诉服务器停在那里。

如何告诉服务器此时停止等待请求？我得到了它的工作，但有2个问题，我想解决。

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，则不会显示发送到客户端的response

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();
    }
}

}

我想出了办法。在响应中添加OnSent事件，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();

    }

}

处理完一个请求后，Restlet停止服务器
