springmvc+redis实现简单消息队列

1、springmvc-redis.xml配置：

2、生产者：

package com.yllt.site.redis.impl;

import com.yllt.site.redis.IRedisPublishDao;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Repository;

/**
 *
 * @author asus
 * @date 2019/8/17
 */
@Repository
public class RedisPublishDaoImpl implements IRedisPublishDao {

    private static Logger logger = LoggerFactory.getLogger(RedisPublishDaoImpl.class);


    @Autowired
    private RedisTemplate redisTemplate;

    static String[] channels = null;
    static {
        if(channels == null){
            channels = new String[]{"channel1", "channel2", "channel3", "channel4", "channel5"};
        }
    }

    @Override
    public void publishMessage(String message) {
        logger.info("消息发布开始..." + message);
        redisTemplate.convertAndSend("channel1", message);
    }
}

3、消费者：

package com.yllt.site.redis.impl;

import com.alibaba.fastjson.JSONObject;
import com.yllt.common.util.CollectionUtil;
import com.yllt.site.domain.Camera;
import com.yllt.site.domain.Trajectory;
import com.yllt.site.service.ICameraService;
import com.yllt.site.service.ITrajectoryService;
import com.yllt.site.util.LatLngUtil;
import org.apache.commons.collections.CollectionUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.connection.Message;
import org.springframework.data.redis.connection.MessageListener;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Service;

import java.awt.geom.Point2D;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

/**
 * 消息订阅者
 * @author asus
 * @date 2019/8/17
 */
@Service("redisSubscribeDaoImpl")
public class RedisSubscribeDaoImpl implements MessageListener {

    private static Logger logger = LoggerFactory.getLogger(RedisSubscribeDaoImpl.class);

    @Autowired
    private RedisTemplate redisTemplate;

    @Override
    public void onMessage(Message message, byte[] pattern) {

        logger.info("消息订阅开始...");
        byte[] body = message.getBody();
        String msgBody = (String) redisTemplate.getValueSerializer().deserialize(body);
        logger.info("接收到消息内容：{}" + msgBody);

        

    }


}

4、测试：

String json = JSONObject.toJSONString(xxx);
redisPublishDao.publishMessage(json);
