此问题在此处已有答案：

I can't update my webapp to Spring Boot 2.6.0 (2.5.7 works but 2.6.0 doesn't)（4个答案）
上个月关门了。
我正在开发一个Sping Boot 应用程序。我必须为两个管理员用户创建凭据。我正在处理Spring Security。遇到循环依赖错误。在不包括Spring Security的情况下，我用post api测试了其他url。它工作正常。但无法理解此错误。

APPLICATION FAILED TO START

Description:

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

┌─────┐
|  securityConfig (field private org.springframework.security.core.userdetails.UserDetailsService strictly.cinema.config.SecurityConfig.userDetailsService)
↑     ↓
|  inMemoryUserDetailsManager defined in class path resource [org/springframework/boot/autoconfigure/security/servlet/UserDetailsServiceAutoConfiguration.class]
└─────┘

Action:

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.
