解决项目报错：@org.springframework.beans.factory.annotation.Autowired(required=true)

项目使用mybatis，启动时报错：

Description:

Field toolsDetailsService in com.cvit.applet.controller.ToolsDetailsController required a bean of type 'com.cvit.applet.mapper.ToolsDetailsMapper' 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.cvit.applet.mapper.ToolsDetailsMapper' in your configuration.

Process finished with exit code 1
 

原因：

 在ToolsDetailsMapper使用的是@Mapper注解，但是在启动类上使用的是@ComponentScan

解决：

修改启动类上的注解

项目启动成功！！！！！
