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！！！！！
