解决Spring Boot产生环形注入的问题

***************************
APPLICATION FAILED TO START
***************************

Description:

The dependencies of some of the beans in the application context form a cycle:

|  MyController (field private com.zhxy.service.AService com.zhxy.controller.MyController.BService)
↑     ↓
|  BService
└─────┘

启动spring boot报以上错误

错误产生原因：BService里面注入AService使用，AService里面又注入BService使用

解决方法：在BService的实现类对 AService   加上Spirng的注解 @Lazy

 

@Autowired

@Lazy

private AService aService ;
