关闭BufferedReader / PrintWriter会关闭套接字连接吗？ [英] Does closing the BufferedReader/PrintWriter close the socket connection?

问题描述

我有一个应用程序，它使用简单的套接字在两个系统之间传递一些字符。我把我的java应用程序作为服务器运行。我建立一个连接很好，甚至传递一条消息。但是，在发送一条消息后，我的连接关闭。

I have an application that uses simple sockets to pass some characters between two systems. I have my java application running as a server. I establish a connection fine, and even pass one message. However, after one message has been sent my connection closes.

从我可以看出来看，好像在关闭 printWriter 和 bufferedReader 套接字本身是否正在关闭？！这很糟糕，因为我有多条消息要在同一个连接上发送。

From what I can tell it appears as if on closing the printWriter and bufferedReader the socket itself is being closed?! This is bad, as I have multiple messages to send on the same connection.

printWriter = new PrintWriter(theServer.getClientSocket().getOutputStream());
bufferedReader = new BufferedReader(new InputStreamReader(theServer.getClientSocket().getInputStream()));


printWriter.println("the line");

printWriter.close(); //Closing on these lines?
bufferedReader.close(); //Closing on these lines?

我吃饱了吗？如何在Java中维护此连接？

Am I full of it? How do I maintain this connection in Java?

推荐答案

是的，关闭任何Writer / Reader将关闭它们包装的所有其他作家和读者。在准备好关闭底层套接字之前，请不要关闭它。

Yes, closing any Writer/Reader will close all other Writers and Readers that they wrap. Don't close it until you are ready to close the underlying socket.
