SpringCloud启动项目报错：Consider defining a bean of type 'java.lang.String' in your configuration.

1.报错信息如下：

Description:

Parameter 0 of method deleteUserLabels in com.XXX.user.service.impl.UserLabelServiceImpl required a bean of type 'java.lang.String' 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 'java.lang.String' in your configuration.

Process finished with exit code 1

2.解决：在启动类的SpringBootApplication上添加(scanBasePackages = {"dao"})就可以了

@SpringBootApplication(scanBasePackages = {"dao"})
