我没看错的话，在480面构建泛型事件的例子中，构建泛型事件的代码和构建用户事件监听器的代码完全重复。

实际的代码应该在
thinking-in-spring-boot-samples/spring-framework-samples/spring-framework-5.0.x-sample/src/main/java/thinking/in/spring/boot/samples/spring5/context/event/GenericEventListenerBootstrap.java
最下面

P483 的对比情况表中说 ApplicationListener 不支持泛型事件，P491 则说“两种途径均能监听一种或多种事件，并且支持泛型事件。”，ApplicationListener 应该是支持泛型事件，只是由于接口泛型范围的限制不能像 @EventListener 直接监听类似事件源 User 对象吧。
