SpringBoot项目启动时报APPLICATION FAILED TO START

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

Description:

Field configService in com.kangning.web.controller.common.CaptchaController required a bean of type 'com.kangning.system.service.ISysConfigService' 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.kangning.system.service.ISysConfigService' in your configuration.

Process finished with exit code 1
解决办法：

1、根据上面提示ISysConfigService接口中没有定义bean对象

2、我使用的是SpringBoot框架，底层是基于Spring，因此定义bean对象需要使用注解来实现

3、我查看了service实现类，发现业务逻辑层Service层没有定义bean对象，因此我使用@Service对该实现类进行定义

4、最后项目启动成功
