套接字连接问题

Question

I am using Socket connection to establish connections in my application. I have a problem when establishing the tunnel with the server: the connection is being closed automatically after 3 minutes for example so when trying again to get data after 3 or 4 minutes, I will have an exception in the inputStream and outputStream. But the thread that opened the connection will not through any kind of exception since I included a try{ ... } catch (Exception ex) { } .
Now the question is, How to keep alive the socket connection to not close at all?

Answer 1

您是否尝试过Socket.setKeepAlive(true) ？

Answer 2

• Fringe areas
• inside buildings
• moving
