Springboot整合mybaits报mapper注入失败@org.springframework.beans.factory.annotation.Autowired(required=true）

Springboot整合mybaits报mapper注入失败@org.springframework.beans.factory.annotation.Autowired(required=true）

报错信息如下：
Field studentMapper in com.ccut.ebusiness.module.school.service.StudentService required a bean of type ‘com.ccut.ebusiness.module.school.mapper.StudentMapper’ that could not be found.

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

解决办法：
首先检查代码有没有问题，看mapper有没有@Mapper 和@Repository这两个注解，
再看pom文件里面导入mybaits依赖没有
