聊天室私聊求思路`

[chump345]

聊天室的公聊已经弄出来了`
但是私聊却无从下手`
用服务器端存取每个建立连接的客户只能得到对方的IP` 和连接的端口号` 存这些信息是用集合的HaspMap来存么？
公聊和私聊貌似可以通过在聊天信息前面加字符来区分`
但是我要选择和哪个用户进行私聊`该怎么和那个用户建立连接呢`
在服务器端也只能得到另一个用户的IP`和端口号`
我是自己一台机器实验` IP都相同` 端口号不同`
在swing里面` 都是自定义的名字`
和某人聊天不可能就要输对方的IP` 和他与服务器连接的端口号吧`
私聊的具体思路是怎样的呢` 求解答`

很简单。。
知道飞鸽传书吗？既然你能在服务器得到所有建立连接的hasMap，那这个map发送并显示在客户端不就好了，客户端通过选择相应的用户，将信息和对话用户的特征发送到服务器，然后由服务器转发，结束。

公聊时 for 循环下0--254 ，私聊 ip

[苍蝇①号]

直接p2p多好啊

其实用qq嘛，多省力

以前学习的时候看过一个聊天系统的例子，是个教学用案例，效率上不敢说多么好，他的思路大概是这样的：
他是用线程来完成的，私聊时单独给这两个用户开一个线程。
当用户A想与用户B私聊时，用户A在页面上点击B选择私聊，服务器接收到A的请求信息，里面包含所需要的信息。
然后服务器向用户B发送一个信息，用户B接收到信息后反馈回服务器一个确认信息
如果同意私聊，则服务器为A和B单独建立一个线程，在其中完成私聊的工作。

不过我看的是J2EE版的，页面端貌似用的AJAX反转来接受服务器发给B用户的请求信息。但你要用swing写的话，可以写一个监听器来监听服务器的请求信息。

很简单啊 你都会公聊了 把服务器端存socket的map发给客户端，可以再客户端上添加个JList 让客户端自己选者和谁私聊 弄个私聊选者框 If选了 按发送的的时候就多发个socket给客户端 客户端就知道你和谁私聊了

刚刚好我写有,自己定义一个自己的CS协议不就行了http://download.csdn.net/source/1795293

[chump345]

就没有TCP/IP的么？

[bawgiitx]

Socket 不就是了

[aaby167]

最关键的问题
用户名一定要是唯一的
不然不知道是和谁私聊

[deathv1]

很好的思路,谢谢指点了
