Spring整合SpringMVC

目的：在controller中能成功的调用service对象中的方法。
在项目启动的时候，就去加载applicationContext.xml的配置文件，在web.xml中配置 ContextLoaderListener监听器(该监听器只能加载WEB-INF目录下的applicationContext.xml的配置文件)。
在controller中注入service对象，调用service对象的方法进行测试

Spring整合MyBatis

目的:把SqlMapConfig.xml配置文件中的内容配置到applicationContext.xml配置文件中
在AccountDao接口中添加@Repository注解
在service中注入dao对象，进行测试
配置Spring的声明式事务管理
