spring-data-redis队列

1、首先加入依赖

<dependency>            <groupId>org.springframework.data</groupId>            <artifactId>spring-data-redis</artifactId>            <version>1.6.4.RELEASE</version>        </dependency>

2、编写MessageListener

import org.springframework.data.redis.connection.Message;import org.springframework.data.redis.connection.MessageListener;/** * Created with IntelliJ IDEA * ProjectName: omp * CreateUser:  sampson * CreateTime : 2016/12/7 * ModifyUser: sampson * Class Description: * To change this template use File | Settings | File Template */public class RedisMessageListener implements MessageListener{    @Override    public void onMessage(Message message, byte[] bytes) {        System.out.println( "Received by RedisMessageListener: " + message.toString() );    }}

3、编写消息委托接口

import java.io.Serializable;import java.util.Map;/** * Created with IntelliJ IDEA * ProjectName: omp * CreateUser:  sampson * CreateTime : 2016/12/7 * ModifyUser: sampson * Class Description: * To change this template use File | Settings | File Template */public interface MessageDelegate {    public void handleMessage(String message);    public void handleMessage(Map<?, ?> message);    public void handleMessage(byte[] message);    public void handleMessage(Serializable message);    public void handleMessage(Serializable message, String channel);}

4、编写实现类

import java.io.Serializable;import java.util.Map;/** * Created with IntelliJ IDEA * ProjectName: omp * CreateUser:  sampson * CreateTime : 2016/12/7 * ModifyUser: sampson * Class Description: * To change this template use File | Settings | File Template */public class DefaultMessageDelegate implements MessageDelegate {    @Override    public void handleMessage(String message) {        System.out.println("handleMessage(String message):" + message);    }    @Override    public void handleMessage(Map<?, ?> message) {        System.out.println("handleMessage(Map<?, ?> message):" + message);    }    @Override    public void handleMessage(byte[] message) {        System.out.println("handleMessage(byte[] message):" + new String(message));    }    @Override    public void handleMessage(Serializable message) {        System.out.println("handleMessage(Serializable message):"+ message.toString());    }    @Override    public void handleMessage(Serializable message, String channel) {        System.out.println("handleMessage:"+ " \t at " + new Date());    }

5、添加spring配置

<bean id="msgListener" class="com.netease.ad.omp.listener.RedisMessageListener" /><bean id="msgDelegateListener" class="com.netease.ad.omp.listener.DefaultMessageDelegate" /><redis:listener-container connection-factory="connectionFactory"><redis:listener ref="msgListener" topic="${queue_name}" /><redis:listener ref="msgDelegateListener" method="handleMessage" topic="nex_adv_audit_queue" /></redis:listener-container><bean id="messageListener" class="org.springframework.data.redis.listener.adapter.MessageListenerAdapter"><constructor-arg><bean class="com.netease.ad.omp.listener.RedisMessageListener" /></constructor-arg></bean><bean id="redisContainer" class="org.springframework.data.redis.listener.RedisMessageListenerContainer"><property name="connectionFactory" ref="connectionFactory" /><property name="messageListeners"><map><entry key-ref="messageListener"><list><bean class="org.springframework.data.redis.listener.ChannelTopic"><constructor-arg value="${queue_name}" /></bean></list></entry></map></property></bean>

此方式只支持publish/subscribe的方式，要不然接收不到发送的消息。

下面是push/pop的方式

生产者的代码比较简单，此处就不写了，只写消费端，需要注意的一点是需要添加轮询机制才可以消费到消息。

public void consume(){        Jedis jedis = null;        try {             //获取redis连接            jedis = RedisUtils.getJRedis();            while (true){                List<String> messageJson = jedis.blpop(TIMEOUT, redisQueueConfig.get("nex.adv.audit.queue"));                if (messageJson.get(1) != null) {                    JSONObject jsonObj = JSONObject.parseObject(messageJson.get(1));                    String json = JSON.toJSONString(jsonObj);                    logger.info("$$$$$$$$$$$    Receive message is {} , at {} ",messageJson.get(1), DateUtils.getCurrentDate()+"     $$$$$$$$$$$");                    //execute busniss code                }            }        } finally {            if (jedis != null) {                RedisUtils.returnResource(jedis);            }        }    }
