Spring 产生mybatis最终需要的动态的mapper对象,EmployeeMapper
1.在dao接口加上实现类,继承sqlDaoSuppertSqlSession对象,实现sqlSession对象
2.不需要自己写dao实现类,框架生成dao实现类
3.基于第二种方式,如果有多个dao,那么就要配置多个bean,太麻烦了,所以直接全部配置好
-->
<!-- 通过myBatis给定的工厂类来创建我们的对应实现类
MapperScannerConfigurer批量生产多个实现类对象
-->
<!-- 批量生产dao对象在spring容器中id默认值为接口名字首字母小写 -->
<!-- 注意在这里没有必要创建多个sqlSessionFactory对象每个实现类一个对象,我们只需一个sqlSessionFactory对象来实现我们的dao对象
这里只需要加sqlSessionFactoryBeanName

<!-- MapperFactoryBean就是生成我们自己的接口实现类对象
只需要用mapperInterface指定name是哪个接口就会创建哪个接口的字节码文件来实现对象,

通过MapperFactoryBean创建出来value所对应的接口实现类对象

实现的EmployeeDao也需要同数据库进行关联,所以也是需要创建sqlSesionFactory对象

dao访问数据库需要sqlSessionFactory,需要进行关联
