简要说明
JEECG[J2EE Code Generation]是一款基于代码生成器的J2EE智能开发框架,借助该框架可以节省50%的工作量,实现代码生成+手工merge的半智能开发
代码生成：根据表生成对应的Bean,Service,Dao,Action,XML,JSP等,增删改查功能直接使用,实现了快速开发
jeecg-mybatis-framework,采用SpringMVC+Mybatis等主流框架
支持数据库: Mysql,Oracle10g
前端:使用Jquery和Easyui技术.JS封装简洁,操作简单.
权限:对菜单,按钮控制.根据登陆用户权限展示拥有的菜单和按钮.
拦截:对所有无权限URL进行拦截,防止手动发送HTTP请求,确保系统全性.
