今天为大家分享一个java语言编的QQ聊天系统，目前系统已经完成了初步功能，后续会进一步完善。整个系统界面漂亮，有完整得源码，希望大家可以喜欢。喜欢的帮忙点赞和关注。一起编程、一起进步
开发环境
开发语言为Java，开发环境Eclipse或者IDEA都可以，数据为MySQL。运行主程序，或者执行打开JAR文件即可以运行本程序。
系统框架
利用JDK自带的SWING框架开发，下载。纯窗体模式，直接运行Main文件即可以。同时带有详细得设计文档。
主要功能
程序启动方法
仿QQ聊天系统的启动如下：
1 运行QQSERVER，启动后台线程
2 运行LoginFrame.java，启动QQ登陆界面
功能需求
1）客户端：提供登录、主窗体及聊天等界面及对应的业务逻辑，向服务器发送相应的服务请求，并接受相应的处理结果。客户端是轻量级的软件，只负责链接远程服务器，并发出相应的服务请求，并不进行核心业务逻辑的处理。具体的处理交给服务器，而客户端只接收服务器处理的结果并显示给用户。
- 服务器：监控登录信息及在线用户信息，接收客户端的服务请求，并做相应的处理，然后将处理结果发送给客户端。服务器负责处理核心的业务逻辑，并负责连接数据库，保存和读取数据。因此，服务器端设计的好坏也直接影响即时通信软件的质量。
主要模块
登陆：登陆QQ ，服务器上查看当前登陆用户信息
分组：添加分组、重命名、删除分组、刷新友好
好友：发送即时聊天、查看好友资料、查看好友聊天记录、删除好友
聊天：支持常见的文本、表情、图片聊天，还支持发送文件、分享音乐视频，发送代码等功能
实现效果
