如何将数据发送到Java中的所有线程客户端? [英] How do I Send Data to All Threaded Clients in Java?

问题描述

我对Java还是很陌生，我正在尝试构建一个非常基本的Java Relay服务器，该服务器将消息从客户端发送到所有连接的客户端.我已经弄清楚如何做线程处理以允许多个连接，但是我很难弄清楚如何将传入的消息回显到所有连接的套接字线程.

I am fairly new to Java, and I am trying to construct a very basic Java Relay server that sends messages from clients to all connected clients. I have figured out how to do threading to allow multiple connections, but I am having trouble figuring out how to echo an incoming message to ALL connected socket threads.

这是我的Main.java来源:

这是我的SocketThread.java来源:

基本上，我想了解当前编码设置的最简单方法，即能够将传入消息从一个客户端发送到所有其他客户端.我目前正在使用Windows telnet客户端作为与此服务器一起使用的客户端.

Basically, I want to know the easiest way with my current coding setup to be able to send an incoming message from one client to all of the other clients. I am currently using the Windows telnet client as the client working with this server.

推荐答案

一种简单的方法是保留一组客户，例如以地图或集合的形式.要将消息发送给所有客户端，请遍历客户端的链接列表，并在每个客户端的发送队列上放置对该消息的引用.当然，您需要通过适当的线程间同步来保护这些结构.

One trivial way is to keep a collection of clients, say as a map or set. To send a message to all clients, you traverse the linked list of clients and put a reference to the message on each client's send queue. You need to protect these structures with proper inter-thread synchronization, of course.
