Setting a time-out limit to readLine()?
提问by Carven
I have the following code that reads response from a POP server through Sockets in Java. But the problem is sometimes, when I use the readLine() function to read from the server and if the server does not reply with any response, my application will hang there, waiting for a response from the server.
我有以下代码通过 Java 中的套接字读取来自 POP 服务器的响应。但问题是有时，当我使用 readLine() 函数从服务器读取时，如果服务器没有回复任何响应，我的应用程序将挂在那里，等待服务器的响应。
socket.connect(new InetSocketAddress("pop.server.com", 110), 3000);
input = socket.getInputStream();
BufferedReader incoming = new BufferedReader(new InputStreamReader(input));
incoming.readLine(); //This line will cause my application to hang if the server does not respond with a reply
Is there a way to set a timeout or some other ways that when the server does not reply after a certain amount of time, the application should stop waiting for a response and continue its other execution?
有没有办法设置超时或其他一些方法，当服务器在一定时间后没有回复时，应用程序应该停止等待响应并继续其其他执行？

I suggest you try Socket.setSoTime(timeout)
