spring+springmvc+mybatis+junit+log4j集成的案例
来源：互联网 发布：今晨送货单打印软件 编辑：程序博客网 时间：2024/04/30 01:30
Spring+Springmvc+Mybatis+junit+log4j集成的一个小案例
1. 本文主要内容
搭建一个整合了Spring、SpringMVC和mybatis的项目框架，同时我也添加了一些示例功能在里面，将主要的功能填充起来。
因为springMVC是基于spring的原因，所以这三个框架整合实际上就是两个框架的整合。
此外，我还整合了log4j用于日志的输出，整合junit用于单元测试。
2. 搭建springmvc框架
首先是导入相关jar包，这里我使用的maven管理这些jar包，不做解释。我是采用xml配置方式搭建框架。直接代码展示。
3．代码展示
