redis监听key失效，单机下出现重复调用

redis config文件开启监听器开关 ，打开notify-keyspace-events Ex

  org.springframework.boot
  spring-boot-starter-data-redis
1.5.9.RELEASE



  org.springframework.data
  spring-data-commons
  1.13.7.RELEASE

@Component
public class RedisListenerConfig {

    @Bean
    public RedisMessageListenerContainer container(RedisConnectionFactory redisConnectionFactory) {
        RedisMessageListenerContainer container = new RedisMessageListenerContainer();
        container.setConnectionFactory(redisConnectionFactory);
        return container;
    }


//不应该再用bean添加监听器，否则出现重复并且同时调用监听

}

@Component
public class RedisKeyExpirationListener extends KeyExpirationEventMessageListener {

//监听
    public RedisKeyExpirationListener(RedisMessageListenerContainer listenerContainer) {
        super(listenerContainer);
    }

    /**
     * 针对redis数据失效事件，进行数据处理
     * @param message
     * @param pattern
     */
    @Override
    public void onMessage(Message message, byte[] pattern) {
        // 用户做自己的业务处理即可,注意message.toString()可以获取失效的key
        String expiredKey = message.toString();
        System.out.println(expiredKey);
    }
}
