Java SocketException 管道损坏

Question

我正在进行客户端到服务器的登录通信。

我遇到了java.net.SocketException:在服务器端破坏了管道。而且我已经缩小了范围问题出现在客户端的一行上。如果我移动这条线的位置，该代码有效。请看下面的代码。

客户端:

    Socket socket = new Socket(Const.destIp, 12101);
    ObjectOutputStream out = new ObjectOutputStream(socket.getOutputStream());
    out.writeObject(this.message);              
    out.close();//Line that cause problem   
    ObjectInputStream in = new ObjectInputStream(socket.getInputStream());
    ServerToClientLogin msg = (ServerToClientLogin) in.readObject();
    //out.close();//move it to here, problem solved
    in.close();
    socket.close();

服务器端:

   while (true) {
     socket = _serverSocket.accept();
     in = new ObjectInputStream(socket.getInputStream());
     msg = (ClientToServerLogin) in.readObject();

     ServerToClientLogin msgToSend = null;
     out = new ObjectOutputStream(socket.getOutputStream());
     msgToSend = handleLoginRequest(msg);
     if(msgToSend != null) out.writeObject(msgToSend);

     try { in.close(); } catch (IOException e) {e.printStackTrace();}
     try { out.close();} catch (IOException e) {e.printStackTrace(); }
     try { socket.close();} catch (IOException e) {e.printStackTrace();}

}

由于 readObject 和 writeObject 是阻塞调用，我不知道为什么提前关闭它会出现这样的问题。

Answer 1

out.close();:关闭此 (out) 输出流并释放与此流关联的所有系统资源。
