/*所有的聊天室用户*/记录登录的用户
private List safeList;
while(true){
//1.接收当前客户端发送来的消息
String currWords= buffReader.readLine();
System.out.println("currWords="+currWords);
//2.服务器(就是"聊天室管理员"的角色)
for(Socket s:safeList){
//不转发给自己
if(s.equals(soc)){
continue;
}
PrintWriter printWriter=new PrintWriter(new OutputStreamWriter(s.getOutputStream(),"utf-8"),true);
printWriter.println(soc.getInetAddress().getHostAddress()+"说:"+currWords);
printWriter.flush();
}
根据socket来判断发送给哪个用户，希望对你有帮助
