本文详细解析了在Spring框架中因循环引用导致的BeanCurrentlyInCreationException异常，并提供了通过使用@Lazy注解来解决该问题的方法。

今天在项目编码过程中，出现了下面的异常：

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

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。

在平时的项目编码过程中，尽量不要导致循环依赖。
