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);
}

}
