spring+mybatis 整合
项目目录：
一、导入pom.xml依赖 最下边有
二、在applicationContext.xml配置连接器和数据库的数据源
三、流程：用户请求数据，springmvc解析url，通过控制器和适配器 找到对应的Controller （UserController），通过自动注入的userService找到里面的hello方法，在查询出结果return值回到userController，
在通过model.addAttribute向页面传参，最后return到页面中。
四、这是测试类的加载配置文件和自动注入（UserDAOTest）来测试更加方便
配置事务：
