redis消息队列有没有

基于Redis消息队列-实现短信服务化
1.Redis实现消息队列原理
常用的消息队列有RabbitMQ,ActiveMQ,个人觉得这种消息队列太大太重,本文介绍下基于Redis的轻量级消息队列服务。
一般来说,消息队列有两种模式,一种是发布者订阅模式,另外一种是生产者和消费者模式。Redis的消息队列,也是基于这2种原理的实现。
发布者和订阅者模式:发布者发送消息到队列,每个订阅者都能收到一样的消息。
生产者和消费者模式:生产者将消息放入队列,多个消费者共同监听,谁先抢到资源,谁就从队列中取走消息去处理。注意,每个消息只能最多被一个消费者接收。
2.Redis消息队列使用场景
在我们的项目中,使用消息队列来实现短信的服务化,任何需要发送短信的模块,都可以直接调用短信服务来完成短信的发送。比如用户系统登录注册短信,订单系统的下单成功的短信等。
3.SpringMVC中实现Redis消息队列
因为我们短信只需要发送一次,所以我们使用的是消息队列的生产者和消费者模式。
3.1引入Maven依赖
引入Redis相应的maven依赖,这里需要spring-data-redis和jedis
//pom.xml <dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-redis</artifactId>
<version>1.6.0.RELEASE</version>
</dependency>
<!-- jedis -->
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.5.1</version>
</dependency>12345678910111213

主要的配置说明:
1.序列化:一般我们向Redis发送一个消息定义的Java对象,这个对象需要序列化。这里使用JdkSerializationRedisSerializer:
<bean id="jdkSerializer" class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" />1
2.发送者:
<bean id="sendMessage" class="com.djt.common.cache.redis.queue.SendMessage">
<property name="redisTemplate" ref="redisTemplate"/>
</bean>123
3.监听者:
<bean id="smsMessageListener"

<property name="delegate" ref="smsMessageDelegateListener" />
<property name="serializer" ref="jdkSerializer" />

<redis:listener-container>
<redis:listener ref="smsMessageListener" method="handleMessage"

</redis:listener-container>123456789
smsMessageListener:消息监听器
redis:listener-container:定义消息监听,method:监听消息执行的方法,serializer:序列化,topic:监听主题(可以理解为队列名称)
3.3代码实现
1.定义短信消息对象SmsMessageVo
public class SmsMessageVo implements Serializable {
//id
private Integer smsId; //手机号
private String mobile; //类型,1:验证码 2:订单通知
private Byte type; //短信创建时间
private Date createDate; //短信消息处理时间
private Date processTime; //短信状态,1:未发送 2:发送成功 3:发送失败
private Byte status; //短信内容
private String content; //省略setter和getter方法
...123456789101112131415161718192021222324
2.定义消息队列发送对象SendMessage
//SendMessage.javapublic class SendMessage { private RedisTemplate<String, Object> redisTemplate; public RedisTemplate<String, Object> getRedisTemplate() { return redisTemplate;
} public void setRedisTemplate(RedisTemplate<String, Object> redisTemplate) { this.redisTemplate = redisTemplate;
} public void sendMessage(String channel, Serializable message) {
redisTemplate.convertAndSend(channel, message);
}
}12345678910111213141516171819202122
3.发送消息
String smsContent = templateToContent(template.getContent(),
regMsgCode);
SmsMessageVo smsMessageVo = new SmsMessageVo();
smsMessageVo.setMobile(mobile);
smsMessageVo.setType((byte) SmsType.VERIFICATION.getType());
smsMessageVo.setChannelId(1);
smsMessageVo.setContent(smsContent);
smsMessageVo.setCreateDate(new Date());
smsMessageVo.setStatus((byte) SmsSendStatus.TO_SEND.getType());
smsMessageVo.setTemplateId(1);
//先把待发送的短信存入数据库
SmsQueue smsQueue = new SmsQueue();
BeanUtils.copyProperties(smsQueue, smsMessageVo);
smsQueueService.addSmsQueue(smsQueue);
//异步发送短信到redis队列
sendMessage.sendMessage(Constants.REDIS_QUEUE_SMS_WEB, smsMessageVo);
//Constants.REDIS_QUEUE_SMS_WEB = "sms_queue_web_online",和applicationContext-redis中topic配置一样123456789101112131415161718192021
4.监听消息
//SmsMessageDelegateListener.java@Component("smsMessageDelegateListener")public class SmsMessageDelegateListener {
@Autowired
private SmsQueueService smsQueueService; //监听Redis消息
public void handleMessage(Serializable message){ if(message instanceof SmsMessageVo){
SmsMessageVo messageVo = (SmsMessageVo) message; //发送短信
SmsSender smsSender = SmsSenderFactory.buildEMaySender();
smsSender.setMobile(messageVo.getMobile());
smsSender.setContent(messageVo.getContent()); boolean sendSucc = false; //判断短信类型
//验证码短信
if(messageVo.getType() == (byte)SmsType.VERIFICATION.getType()){
sendSucc = smsSender.send();
} if(!sendSucc){ return;
} // 异步更新短信表状态为发送成功
final Integer smsId = messageVo.getSmsId();
Executor executor = Executors.newSingleThreadExecutor();
executor.execute(new Runnable() { public void run() {
SmsQueue smsQueue = new SmsQueue();
smsQueue.setSmsId(smsId);
smsQueue.setStatus((byte)SmsSendStatus.SEND.getType());
smsQueue.setProcessTime(new Date());
smsQueueService.updateSmsQueue(smsQueue);
}
});
}
}
}123456789101112131415161718192021222324252627282930313233343536373839404142434445
