错误翻译

org.springframework.beans.factory.BeanCreationNotAllowedException: Error creating bean with name 'nacosAutoServiceRegistration': Singleton bean creation not allowed while singletons of this factory are in destruction (Do not request a bean from a BeanFactory in a destroy method implementation!)

org.springframework.beans.factory.BeanCreationNotAllowedException: 创建名为 'nacosAutoServiceRegistration' 的 Bean 时出错：在 Factory 的单例 Bean 销毁过程中不允许创建单例 Bean（请勿在销毁方法实现中从 BeanFactory 请求 Bean！）

原因分析

在 Spring 应用上下文关闭（销毁）过程中，nacosAutoServiceRegistration 这个 Bean 的创建被触发了，但此时 BeanFactory 处于销毁状态，不允许再创建新的 Bean。这通常发生在 ContextClosedEvent 的监听器中，该监听器尝试访问或创建已经被销毁的 Bean。

解决方案

  • 检查 ContextClosedEvent 监听器：
    • 查找所有实现了 ApplicationListener 接口的类，或者使用了 @EventListener(ContextClosedEvent.class) 注解的方法。
  • 移除或修改逻辑：
    • 在该监听器的方法中，检查是否有代码尝试获取或创建 nacosAutoServiceRegistration Bean。如果存在，请移除该代码，或者确保它不会在应用上下文销毁阶段执行。例如，如果它是一个注册/注销逻辑，可能需要在销毁前就执行完毕。
  • 延迟销毁或条件性执行：
    • 如果必须在该监听器中处理某些逻辑，可以考虑使用 @PreDestroy 注解在 Bean 真正销毁前执行清理操作，或者在监听器逻辑中添加条件判断，避免在销毁阶段进行不必要的操作。

    预防措施

  • 避免在销毁阶段访问 Bean：应用程序上下文销毁时，Bean 正在被清理，此时不应再尝试创建或访问 Bean。检查销毁阶段的生命周期回调和事件监听器。

  • 管理 Bean 的生命周期：确保 Bean 的创建和销毁过程是按照预期的顺序进行，特别是在涉及多个 Bean 之间的依赖关系时。Spring 的生命周期管理非常重要，不当的干预可能导致此类问题。
