KeyExpiredListener.java

public class KeyExpiredListener extends JedisPubSub {
    public KeyExpiredListener() {
    }

    @Override
    public void onMessage(String channel, String message) {       //收到消息会调用
        System.out.println(String.format("receive redis published message, channel %s, message %s", channel, message));
    }

    @Override
    public void onSubscribe(String channel, int subscribedChannels) {    //订阅了频道会调用
        System.out.println(String.format("subscribe redis channel success, channel %s, subscribedChannels %d",
                channel, subscribedChannels));
    }

    @Override
    public void onUnsubscribe(String channel, int subscribedChannels) {   //取消订阅 会调用
        System.out.println(String.format("unsubscribe redis channel, channel %s, subscribedChannels %d",
                channel, subscribedChannels));
    }
}

 

AppListener.java

public abstract class AppListener extends JbootAppListenerBase {

    @Override
    public void onInterceptorConfig(Interceptors interceptors) {
        super.onInterceptorConfig(interceptors);
        interceptors.add(new SessionInViewInterceptor());
    }

    @Override
    public void onEngineConfig(Engine me) {

    }

    @Override
    public void onStart() {
        Aop.inject(this);

        Jboot.getRedis().subscribe(new KeyExpiredListener(), "__keyevent@0__:expired");
    }

}

 

测试代码

Cache.set("test-101", "101", 30);
Cache.set("test-201", "201", 60);
Cache.set("test-301", "301", 90);

 

效果

receive redis published message, channel __keyevent@0__:expired, message xxxx:S:test-101
receive redis published message, channel __keyevent@0__:expired, message xxxx:S:test-201
receive redis published message, channel __keyevent@0__:expired, message xxxx:S:test-301
