Spring Bean生命周期

Spring Bean 的生命周期包括创建、初始化、使用、销毁等过程。

Spring Bean 的生命周期

+ * +*
  • 实例化阶段：Bean 被实例化，Bean 实例化后，Bean 处于未初始化状态。
    • +*
  • 初始化阶段：Bean 完成实例化后，Bean 处于初始化状态，Bean 实例变量可以被赋值。
    • +*
      +*

    • BeanPostProcessor.postProcessAfterInitialization
      • +*
    +*
  • 使用阶段：Bean 完成初始化后，Bean 处于可使用状态，Bean 可以被使用。
    • +*
  • 销毁阶段：Bean 不再被使用时，Bean 处于销毁状态，Bean 实例将被销毁。
