问题描述

我正在使用Socket和ServerSocket编写一个Java客户端/服务器程序。多个客户端立即连接到服务器。检查客户端连接是否已从服务器端断开连接的最佳方法是什么？现在，我只是得到一个SocketException尝试写入断开的客户端。

I am writing a Java client/server program using Socket and ServerSocket. Multiple clients connect to the server at once. What is the best way to check if a client connection has disconnected from the server side? Right now, I'm just getting a SocketException when attempting to write to a disconnected client.

推荐答案

检测断开连接的最佳方法是让另一端发送心跳，数据。

The best way to detect a disconnection is to have the other end send a heartbeat and have the reader timeout when there is no data.
