spring中訂閱redis索引值到期訊息通知

1、首先啟用redis通知功能（ubuntu下操作）：
編輯/etc/redis/redis.conf檔案，添加或啟用以下內容（到期通知）：

notify-keyspace-events Ex

或者登陸redis-cli之後，輸入以下命令：

config set notify-keyspace-events Ex

更多通知詳見：http://redis.io/topics/notifications#configuration

2、Java Spring中配置監聽

介面類：

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);}

實作類別：

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;@Servicepublic 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：
