Spring 会话处理:未收到 HttpSessionDestroyedEvent [英] Spring session handling: HttpSessionDestroyedEvent not received

问题描述

我有一个 Web 应用程序，其中在 web.xml 中添加了 HttpSessionEventPublisher 作为侦听器.Web 应用程序在 Jetty 7.x 上运行，我们使用的是 Spring 3.1.1.

I have a web app where in the web.xml I have added the HttpSessionEventPublisher as listener. The web app runs on Jetty 7.x and we are using Spring 3.1.1.

这应该将 HttpSessionCreatedEvent 和 HttpSessionDestroyedEvent 触发到 Spring 上下文事件侦听器.

This is supposed to fire HttpSessionCreatedEvent and HttpSessionDestroyedEvent to Spring context event listeners.

我有一个实现 ApplicationListener 的 Bean (@Controller).ApplicationEvent 是HttpSessionCreatedEvent 和HttpSessionDestroyedEvent 的公共父类.当我现在登录到我的 Web 应用程序或从中注销时，我希望这些事件被触发到 onApplicationEvent(ApplicationEvent event) 方法.我收到了其他事件，比如一些请求处理事件，但没有出现预期的事件.我已经稍微跟踪了该应用程序，HttpSessionEventPublisher 肯定会将事件触发到上下文，但没有接近侦听器.我在这里想念什么?

I have a Bean (@Controller) that implements ApplicationListener<ApplicationEvent>. ApplicationEvent is the common parent class of HttpSessionCreatedEvent and HttpSessionDestroyedEvent. When I now login to my web application or log out from it I'd expect these events to be fired to the onApplicationEvent(ApplicationEvent event) method. I have received other events like some request handling event, but the expected event's didn't show up. I have traced the app a bit, the HttpSessionEventPublisher definitely fires the event to the context, but the listener isn't approached. what do I miss here?

推荐答案

问题在于 HttpSessionEventPublisher 根据 javadoc 在Spring Root WebApplicationContext"上发布事件，这是通过 ContextLoaderListener 条目.另一方面，您的 @Controller 可能是通过完全不同的应用程序上下文注册的 - 通过 DispatcherServlet 注册的应用程序上下文.所以我建议你创建一个不同的 ApplicationListener，将它注册到 Root WebapplicationContext，然后事件应该通过.

The issue is that HttpSessionEventPublisher publishes events on the "Spring Root WebApplicationContext" per the javadoc, this is the application context registered through ContextLoaderListener entry in your web.xml file. Your @Controller on the other hand is probably registered through a different application context altogether - the one registered through the DispatcherServlet. So I would suggest that you create a different ApplicationListener, register it to the Root WebapplicationContext, the events should come through then.
