Spring依赖循环问题

Spring依赖循环问题

最近在写项目时，新加了一个@Asyn方法，本来能够正常运行的代码，报了如下错误：

Caused by: org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name ‘apolloInfoService’: Bean with name ‘apolloInfoService’ has been injected into other beans [adminSmRoleServiceWithApolloImpl] 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.

报了循环依赖，想到spring本身是可以解决单例的循环依赖问题的，于是百度，这篇文章详细介绍了原理和源码实现。
一起来读Spring源码吧（四）循环依赖踩坑笔记

解决方法：

1. 使用@Asyn，不要循环依赖
2. 可以在循环依赖的类上加@Lazy注解
3. 通过后置处理器设置allowRawInjectionDespiteWrapping=true
