Spring高版本循环依赖报错问题

在升级了springboot2.7之后的版本，突然出现了问题，说是循环引用了，这个在之前的逻辑中确实出现了互相引用service的问题，但是修改的话，改动太大所以直接就开启了。

在application.yml放在spring下面
    main:
        allow-bean-definition-overriding: true
        allow-circular-references: true

**2.6.0后关闭了循环引用，需要开启**

报错信息：
    org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name '*****.BasicCompanyFourInfoController':
    Unsatisfied dependency expressed through field 'loginFacade'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException:
    Error creating bean with name '*****.protection.application.service.impl.LoginFacadeImpl': Unsatisfied dependency expressed through field 'checkTaskService';
    nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name '*****.protection.domain.operation.impl.CheckTaskServiceImpl':
    Unsatisfied dependency expressed through field 'checkPlanService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException:
    Error creating bean with name '*****.protection.domain.operation.impl.CheckPlanServiceImpl': Unsatisfied dependency expressed through field 'checkTaskService';
    nested exception is org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name '*****.protection.domain.operation.impl.CheckTaskServiceImpl':
    Requested bean is currently in creation: Is there an unresolvable circular reference?

然后spring提示：

Relying upon circular references is discouraged and they are prohibited by default. Update your
     application to remove the dependency cycle between beans. As a last resort,
      it may be possible to break the cycle automatically by setting spring.main.allow-circular-references to true.

大概意思就是：不鼓励依赖循环引用，默认情况下禁止使用循环引用。想要开启就设置下所以设置上面的就好了。
