***************************
APPLICATION FAILED TO START
***************************

Description:

Field userMapper in com.mryang.springboot.SpringbootApplication required a bean of type 'com.mryang.springboot.mapper.UserMapper' that could not be found.

The injection point has the following annotations:
	- @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'com.mryang.springboot.mapper.UserMapper' in your configuration.


Process finished with exit code 1

错误原因：

mapper接口没有被spring管理，缺少mapper接口的bean配置

解决方法：

在mapper接口中加上@Mapper注解即可
