- - ### org.springframework.context.event中GenericApplicationListener的使用

    实现GenericApplicationListener的org.springframework.context.event中的类
    限定符和类型 | 类和说明
    --- | ---
    `class` | `ApplicationListenerMethodAdapter` `GenericApplicationListener` adapter that delegates the processing of an event to an `EventListener` annotated method.
    `class` | `GenericApplicationListenerAdapter` `GenericApplicationListener` adapter that determines supported event types through introspecting the generically declared type of the target listener.
    `class` | `SourceFilteringListener` `ApplicationListener` decorator that filters events from a specified event source, invoking its delegate listener for matching `ApplicationEvent` objects only.
