SpringBoot项目处理循环依赖问题（circular reference）

1 问题

• springBoot启动失败，报错BeanCurrentlyInCreationException

org.springframework.beans.factory.BeanCurrentlyInCreationException:
Error creating bean with name 'AxxxxService': 
Bean with name 'BxxxxService' 
has been injected into other beans [CxxxxService] 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. 

2 解决方法

• 1 找到中括号中的Service： CxxxxService
• 2 在CxxxxService中找到 BxxxxService(离得最近的，如果看不懂英文的话）的声明
• 3 在BxxxService的声明上加注解 @Lazy
  注： 如果中括号中不止一个CxxxxService,每个都要这样做，加上@Lazy

3 悔恨

• 我没有一开始就百度，解决方案，而是自以为是地组装新的Service类
• 今天遇到一个中括号里有多个类的，要改的多了，就搜索一下人家的解决方案，流下了悔恨的眼泪
• 现在才把代码调整回去了，已经晚上10点多了
• 本来想试试revert, 过去太久，太多commit了，害怕了，退缩了
