springboot redis监控失效key

1.引入依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

2.创建超时监听

package com.jeesite.modules.test.RedisManage;

import org.springframework.data.redis.connection.Message;
import org.springframework.data.redis.listener.KeyExpirationEventMessageListener;
import org.springframework.data.redis.listener.RedisMessageListenerContainer;
import org.springframework.stereotype.Component;

/**
 * redis失效key监听
 *
 * @author 郑文
 *
 */
@Component
public class RedisKeyExpirationListener extends KeyExpirationEventMessageListener {
    public RedisKeyExpirationListener(RedisMessageListenerContainer listenerContainer) {
        super(listenerContainer);
    }

    /**
     * redis失效key事件处理
     * @param message
     * @param pattern
     */
    @Override
    public void onMessage(Message message, byte[] pattern) {
        // message.toString()可以获取失效的key
        String expiredKey = message.toString();
        System.out.println("-------------------");
        System.out.println("失效key："+message.getBody());
    }
}
