Demo演示：

消息发布端:

package com.iwhere.testredis;

import org.junit.Before;
import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.data.redis.core.StringRedisTemplate;

/**
 * 测试redis做消息
 * @author 231
 *
 */
public class TestRedis {

    private StringRedisTemplate redisTemplate;
    @Before
    public void before() {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath:redis-context.xml");
        redisTemplate = context.getBean(StringRedisTemplate.class);
    }

    private String channel = "amap";
    /**
     * 测试连接
     */
    @Test
    public void test1() {
        String message = "c26c4ac0-37a3-4277-9020-bfa274c058f5|526548902996869120|Success";
        redisTemplate.convertAndSend(channel, message);
        System.out.println("发送完成");
    }
}

消息接收端

package com.iwhere.redis.sub;

import java.io.UnsupportedEncodingException;

import org.aspectj.bridge.Message;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.connection.MessageListener;
import org.springframework.data.redis.listener.ChannelTopic;

/**
 *
 */
public class MessageDelegateListenerImpl implements MessageListener {

    @Autowired
    private ChannelTopic channelTopic;

    @Override
    public void onMessage(org.springframework.data.redis.connection.Message message, byte[] pattern) {

        byte[] bytes = message.getBody();// ""里面的参数为需要转化的编码，一般是ISO8859-1
        try {
            String str = new String(bytes, "utf-8");
            System.out.println("I am here" + str + ": " +  channelTopic.getTopic());
        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        System.out.println(message);
    }
