关闭 BufferedReader/PrintWriter 是否会关闭套接字连接? [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.我的 Java 应用程序作为服务器运行.我很好地建立了连接，甚至传递了一条消息.但是，发送完一条消息后，我的连接就会关闭.

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.

据我所知，似乎在关闭 printWriter 和 bufferedReader 时，套接字本身正在关闭?！这很糟糕，因为我要在同一个连接上发送多条消息.

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?我如何在 Java 中维护这种连接?

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 Writers 和 Readers.在您准备好关闭底层套接字之前不要关闭它.

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.
