@Mapper 和 @MapperScan 都是 mybatis 的注解。
两个注解都是在告诉 mybatis 这里有一个接口类。
@Mapper
但是，有一个问题，就是每一个接口类都要有一个 @Mapper，就会非常麻烦。
@MapperScan
Scan 有浏览的意思，如果在启动类上进行注解
@MapperScan({"com.aop8.emp.mapper","com.aop8.dep.mapper"})
他们就会把上面两个文件夹下面的所有接口类都注册到 mybatis 中。
还支持表达式。
@MapperScan({"com.aop8.*.mapper","com.baidu.*.mapper"})
