话说两星期又过liao~~

之前的仿扣扣雏形抢先升级，速度满血复活，如果你还宅在宿舍，如果你还觉得生活无聊，如果你还依然单身，嚯，嚯嚯，嚯嚯嚯~~不要问，不要说，一切尽在空间中，oh my god~~，你一定还不知道我在说什么吧，没错，这就是它的神秘之处，电脑前的你还等什么，赶快扶稳键盘，握紧鼠标，一起..........

呃，好了，时间到，不吹了~~

下面插播一就段广告哈（不要回来，马上走开~~）

你还为广石化的选课而烦恼吗，你还在为广石化的土豆鸡到底ou了多长时间而苦恼吗.......没错....@##￥%…￥￥##@....

广告回来···呵呵，好了好了··这次真的不吹了`````

搞了差不多两星期，这粥终于熬好啦.....

仿QQ聊天软件 chat2_1版本更新内容
1、支持广播群聊功能，可提取电脑用户名作为区分名称
2、新增优化登录和登录ing界面（高仿QQ2012）
3、每台计算机上可支持多个客户端同时运行
4、暂不开放帐号申请，暂无好友、个人信息保存（些版本尚未添加数据库）
5、默认端口依然是good number： 8888端口（用此高端口可避免和一般软件相互占用端口造成登录失败）
6、优化服务端，新增系统消息显示，可时时监控服务运行状态
7、服务端新增聊天监控，可观察各客户端的聊天信息
8、把验证登录信息移至服务器端

注：此版本暂无连接数据库，所以统一登录QQ为724447804（登录窗口中有保存为默认帐号）密码：a

(这次聊天界面暂时没怎么优化，呵呵，嗯，先将就下吧.....下一版本有空再弄弄吧，这次主要是想和正在学着java的同学交流分享下编程的一些东西而已，希望高手见了，不要太见笑好了....)

登录窗口

登录中窗口

server服务器窗口

分享下代码，希望有兴趣的同志可以看看这东西，这次的2_1版本中还有很多弊端，但聊天框基本上都写了的

这次代码中还有很多不成熟的地方，希望能得到一些高手们的建议吧，先谢谢给评论的同志们啦.....呵呵~~~
