你如何处理 Java 中的套接字断开连接? [英] How do you handle Socket Disconnecting in Java?

问题描述

大家好.我有一个使用 ServerSocket 和 Socket 类用 Java 编写的服务器.

Hey all. I have a server written in java using the ServerSocket and Socket classes.

我希望能够检测和处理断开连接，然后在必要时重新连接新客户端.

I want to be able to detect and handle disconnects, and then reconnect a new client if necessary.

检测客户端断开连接、关闭套接字然后接受新客户端的正确程序是什么?

What is the proper procedure to detect client disconnections, close the socket, and then accept new clients?

推荐答案

据推测，您正在从套接字读取，可能是在输入流上使用包装器，例如 BufferedReader.在这种情况下，您可以在相应的读取操作返回 -1(对于原始 read() 调用)或 null(对于 readLine() 调用)时检测流结束.

Presumably, you're reading from the socket, perhaps using a wrapper over the input stream, such as a BufferedReader. In this case, you can detect the end-of-stream when the corresponding read operation returns -1 (for raw read() calls), or null (for readLine() calls).

某些操作在关闭的套接字上执行时会导致 SocketException，您也需要适当处理.

Certain operations will cause a SocketException when performed on a closed socket, which you will also need to deal with appropriately.
