参考链接 Spring报错：has been injected into other beans [xxx] in its raw version as part of a circular reference
一、问题描述
在启动项目时，遇到Spring报错，但不影响正常使用，经整理，报错信息如下：
org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'systemService': Bean with name 'systemService' has been injected into other beans [yeeDoctorsImpactService] in its raw version as part of a circular reference, but has eventually been wrapped. This means that said other beans do not use the final version of the bean. This is often the result of over-eager type matching - consider using 'getBeanNamesOfType' with the 'allowEagerInit' flag turned off, for example.
二、项目简述
1、 SSM结构， Spring 全家桶4.3+ 。
2、使用 @Autowired 注解注入需要用到的 Service 。
三、问题解决
1、原因： systemService 类中注入了 yeeDoctorsImpactService ， 而在 yeeDoctorsImpactService 类中也注入了 systemService ，从而引起该异常。 （循环引用）
2、解决： systemService 类注入 yeeDoctorsImpactService 时，增加注解 @Lazy ，反之同理。
3、@Lazy 注解路径为： org.springframework.context.annotation.Lazy 。
