## 【Exception】Spring报错：Bean with name 'xxx' 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** 。
