Spring Session - 不调用 SessionDestroyedEvent

Question

我有一个 Spring 应用程序，其中 session 存储在具有短超时 (1m) 的 redis 中。我想在我的 session 超时后调用一个函数，但是 SessionDestroyedEvent @EventListener 没有被调用。

session 监听器.java:

import org.springframework.context.event.EventListener;
import org.springframework.session.events.SessionCreatedEvent;
import org.springframework.session.events.SessionDestroyedEvent;
import org.springframework.stereotype.Component;

@Component
public class SessionListener {

    @EventListener
    public void sessionCreated(SessionCreatedEvent event) {
        System.out.println("created"); // gets called
    }

    @EventListener
    public void sessionDestroyed(SessionDestroyedEvent event) {
        System.out.println("destroyed"); // never gets called

    }

}

应用程序属性:

spring.session.store-type=redis
server.servlet.session.timeout=1m

注意事项:

1. 调用 SessionCreatedEvent 上的 eventListener
2. redis 的 session 在超时后消失

Answer 1

第SessionDeletedEvent and SessionExpiredEvent在 Spring Session 引用中描述了如何清理 session 。

来自文档:

Firing SessionDeletedEvent or SessionExpiredEvent is made available through the SessionMessageListener which listens to Redis Keyspace events. In order for this to work, Redis Keyspace events for Generic commands and Expired events needs to be enabled
