Consider defining a bean of type ‘**.Mapper’ in your configuration

报错

Description:
Field mapper in com.**.service.StudentServiceImpl required a bean of type 'com.**.mapper.StudentxMapper' 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.**.mapper.StudentxMapper' in your configuration.

           

错误排查

application.properties

中的内容是：

#整合mybatis
mybatis.type-aliases-package=com.chen.pojo
mybatis.mapper-locations=classpath:mapper/*.xml
           

但也挡不住爆红，开始以为是spring 的问题

后来发现没有导入 sprin-boot的mybatis的start包。

解决方案

<dependency>
 <groupId>org.mybatis.spring.boot</groupId>
 <artifactId>mybatis-spring-boot-starter</artifactId>
 <version>2.2.0</version>
</dependency>
           

运行OK。

整合的时候一定要仔细查看导入的包，不然空费时间。
