Thrift Async Client不会停止

Question

我想知道为什么如果没有将代码标记为1，即使结果不是null，应用程序也会继续运行并且永不停止，并且标记为2的代码不会出现1。打印预期结果。

但是，如果代码标记为null，则应用程序在结果不是2时结束，并打印标记为private Object response=null; public Object getResponse() { return response; } @Override public void onComplete(Object response) { this.response=response; } @Override public void onError(Exception exception) { exception.printStackTrace(); } 的代码。

AsyncMethodCallback

public static void main(String[] args) {
    try {
        TNonblockingServerSocket serverSocket=new TNonblockingServerSocket(10005);
        Hello.Processor<Hello.Iface> processor=new Hello.Processor<>(new HelloServiceImpl());
        TNonblockingServer.Args serverArgs=new TNonblockingServer.Args(serverSocket);
        TProtocolFactory factory=new TBinaryProtocol.Factory();
        serverArgs.transportFactory(new TFramedTransport.Factory());
        serverArgs.processor(processor);
        serverArgs.protocolFactory(factory);
        TServer server=new TNonblockingServer(serverArgs);
        System.out.println("server start....");
        server.serve();

    } catch (TTransportException e) {
        e.printStackTrace();
    }
}

        TNonblockingSocket socket=new TNonblockingSocket("localhost",10005);
        TProtocolFactory protocolFactory=new TBinaryProtocol.Factory();
        Hello.AsyncClient asyncClient=new Hello.AsyncClient(protocolFactory,clientManager,socket);
        System.out.println("Client calls....");
        MethodCallback<Integer> methodCallback=new MethodCallback<>();
        asyncClient.helloInt(14,methodCallback);
        Object result=methodCallback.getResponse();
        while (result==null){
            result=methodCallback.getResponse();
            // System.out.println("result is "+result); //1
        }
        System.out.println(result); //2

    } catch (IOException | TException e) {
        e.printStackTrace();
    }
}
