spring中订阅redis键值过期消息通知

1、首先启用redis通知功能（ubuntu下操作）：
编辑/etc/redis/redis.conf文件，添加或启用以下内容（过期通知）：

notify-keyspace-events Ex

或者登陆redis-cli之后，输入以下命令：

config set notify-keyspace-events Ex

更多通知详见：http://redis.io/topics/notifications#configuration

2、Java Spring中配置监听

接口类：

import java.io.Serializable;
import java.util.Map;

public interface IMessageDelegate {
  void handleMessage(String message);
  void handleMessage(Map message);
  void handleMessage(byte[] message);
  void handleMessage(Serializable message);
  void handleMessage(Serializable message, String channel);
}

实现类：

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.stereotype.Service;
import rhxtune.smarthome.api.interfaces.IMessageDelegate;
import java.io.Serializable;
import java.util.Map;

@Service
public class DefaultMessageDelegate implements IMessageDelegate {
    public static Logger logger = LogManager.getLogger(DefaultMessageDelegate.class.getName());

    @Override
    public void handleMessage(String message) {
        logger.info("handleMessage1:" +  message);
    }

    @Override
    public void handleMessage(Map message) {
        logger.info("handleMessage2:" +  message);
    }

    @Override
    public void handleMessage(byte[] message) {
        logger.info("handleMessage3:" +  message);
    }

    @Override
    public void handleMessage(Serializable message) {
        logger.info("handleMessage4:" +  message);
    }

    @Override
    public void handleMessage(Serializable message, String channel) {
        logger.info("handleMessage5:" +  message + channel);
    }
}

spring-redis.xml中配置：
