趁着周末自己复习搭建了一个SpringMVC小demo。有很多不正之处还请指教。有什么问题可以私信或者下方留言。有关Ioc可以参考,有关AOP可以参考

项目用到的技术：

开发环境IDE eclipse Neon 服务器Tomcat8.0 JDK 1.8 （正在学习1.8所以还没有使用到新的语法） 数据库 Mysql5.5 Maven 3.3.9 分页框架 pager taglib 后台框架 Spring4.2.4 SpringMVC4.2.4 Hibernate4.3.10 前端框架 Bootstrap3.3.10 日志采用了 log4j 测试框架 Spring-test + junit4

完整项目可以到 下面贴出项目源码。
