项目controller service都写好启动的时候出现了错误

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

Description:

Field nodeParameterService in com.smartcity.web.controller.scenery.ObjNodeParameterController required a bean of type 'com.smartcity.scenery.service.IObjNodeParameterService' 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.smartcity.scenery.service.IObjNodeParameterService' in your configuration.

 刚开始我以为是controller中注入接口类出现了问题  重新导入 并重启电脑无效。然后去网上差了一下，发现是因为service实现类没有被扫描到  缺少了@Service注解

加成后成功启动
