Bean with name ‘‘ has been injected into other beans [] in its raw version as part of a circular ref

Bean with name ‘你自己项目中A类’ has been injected into other beans [你自己项目中类另外的B类] 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.

1、原因： 你自己项目中A 类中注入了你自己项目中类另外的B类， 而在 你自己项目中类另外的B 类中也注入了 你自己项目中A 类 ，从而引起该异常。（循环引用）

2、解决： 你自己项目中A 类注入 你自己项目中类另外的B类时，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。
