Springboot循环依赖问题： Bean with name ‘xxxxService‘ has been injected into other beans

Error creating bean with name 'xxxxService': Bean with name 'xxxxService' has been injected into other beans [.....] 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.

查找好久，都说是循环依赖的问题，我就在想：但是springboot不是自己解决的循环依赖的问题了吗？一直找不到原因，直到看了https://blog.csdn.net/dx125806/article/details/50128837这篇帖子下一个老哥的评论：

ben_harden: spring默认是支持循环依赖，allowCircularRefrence默认为true。
也可以手动设置applicationContext.setAllowCircularReferences(false); 
产生这个问题原因：in its raw version as part of a circular reference, but has eventually been wrapped.
应该是项目中对某个类进行了wrapped,可能是开启异步导致

最后发现是在xxxservice中添加了@Async的注解导致的。
