今天就跟大家聊聊有关java Socket多线程服务器源代码是怎样的，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。

java Socket多线程需要我们不断的学习，在学习的时候我们就会发现在服务器的配置上有不少的问题。下面我们就来看看服务器源代码是如何编写的，以便大家更好的使用java Socket多线程。

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.ServerSocket;

private static List list = new ArrayList();
// 保存连接对象
private ExecutorService exec;
private ServerSocket server;
public static void main(String[] args) {
new ChatServer();
}
public ChatServer() {
try {
server = new ServerSocket(PORT);
exec = Executors.newCachedThreadPool();
System.out.println("服务器已启动！");
Socket client = null;
while (true) {
client = server.accept(); // 接收客户连接
list.add(client);
exec.execute(new ChatTask(client));
}
} catch (IOException e) {
e.printStackTrace();
}
}
static class ChatTask implements Runnable {
private Socket socket;
private BufferedReader br;
private PrintWriter pw;
private String msg;
public ChatTask(Socket socket) throws IOException {
this.socket = socket;
br = new BufferedReader(new InputStreamReader(socket
.getInputStream()));
msg = "【" + this.socket.getInetAddress() + "】
进入聊天室！当前聊天室有【"
+ list.size() + "】人";
sendMessage();
}
public void run() {
try {
while ((msg = br.readLine()) != null) {
if (msg.trim().equals("bye")) {
list.remove(socket);
br.close();
pw.close();
msg = "【" + socket.getInetAddress() + "】
离开聊天室！当前聊天室有【"

break;
} else {

sendMessage();
}
}
} catch (IOException e) {
e.printStackTrace();
}
}
/**

*/
private void sendMessage() throws IOException {
System.out.println(msg);
for (Socket client : list) {
pw = new PrintWriter(client.getOutputStream(), true);
pw.println(msg);
}
}
}
}
