ServerSocket+Swing+SQL Server2008聊天系统（好友私聊，聊天室群聊）
来源：互联网 发布：跳舞毯哪款最好 知乎 编辑：程序博客网 时间：2024/05/15 23:50
MonsterChatRoom(怪聊聊天系统)
本系统采用ServerSocket+Swing+SQL Server2008编写
主要分为三个模块：登录模块，用户信息展示模块，聊天模块
登录模块
如上图所见：后台采用账户名为唯一标识，通过其获取数据库中的数据；登录主界面，实现了三个相关的界面，和记住密码，保存在数据库中，方便下次登录；密码找回，如果账号存在，下面的信息填写中与数据库注册信息核对两条以上，那么密码框向用户开启可编辑状态，重新找回密码成功！

私聊
如上图：好友之间可以进行私人聊天，当然，这里的离线消息，也是可以接收到的
，同时界面的历史记录用户也是可以获取到的，后台都有记录群聊房间
（这里采用了网上一兄弟的界面绘制） 如上图：不管是否好友的关系，只要注册了用户，就可以和所有用户进行通信，（这里开启了一个单独的子服务端口）服务器也可以进行监听所有消息，可以对所有用户发送消息
本项目，采用SQL Server2008数据库做后台，共四张简单表结构组成
主要针对用户的基本信息结构设计
如上图：整个项目的目录结构
因为代码量比较大，所以没有全部贴出，有需要的可以去我的资源中下载整个项目源码包括（项目源码，后台数据库，PPT简介）！
因为是个人原创耗时一个礼拜，所以请赏5个金币吧！感谢了！
