Spring循环依赖那些事儿（含Spring详细流程图）

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'taskPunchEvent': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'playContentService': Bean with name 'playContentService' has been injected into other beans [toVoConvertor] 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.
