spring集成rabbitMq(非springboot)
首先 , pom文件需要加入spring集成rabbitMq的依赖:
<dependency> <groupId>org.springframework.amqp</groupId> <artifactId>spring-rabbit</artifactId> <version>1.6.3.RELEASE</version> </dependency>
发送端spring的xml配置:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:task="http://www.springframework.org/schema/task" xmlns:rabbit="http://www.springframework.org/schema/rabbit" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.0.xsd http://www.springframework.org/schema/rabbit http://www.springframework.org/schema/rabbit/spring-rabbit-1.0.xsd"> <!-- rabbitMQ配置 --> <bean id="rabbitConnectionFactory" class="org.springframework.amqp.rabbit.connection.CachingConnectionFactory"> <constructor-arg value="192.168.1.11"/> <property name="username" value="root"/> <property name="password" value="lee13233"/> <property name="channelCacheSize" value="8"/> <property name="port" value="5672"></property> </bean> <rabbit:admin connection-factory="rabbitConnectionFactory"/> <!-- autoDelete:是否自动删除 durable:持久化 --> <rabbit:queue name="test123queue" durable="true"/> <rabbit:queue name="test321queue" durable="true"/> <!-- topic主题 --> <rabbit:topic-exchange name="leo.pay.topic.exchange" xmlns="http://www.springframework.org/schema/rabbit" durable="true"> <bindings> <binding queue="test123queue" pattern="*.*.test123" /> <binding queue="test321queue" pattern="test321.#" /> </bindings> </rabbit:topic-exchange> <!-- 创建rabbitTemplate 消息模板类 --> <bean id="rabbitTemplate" class="org.springframework.amqp.rabbit.core.RabbitTemplate"> <constructor-arg ref="rabbitConnectionFactory"></constructor-arg> </bean> </beans>
发送端的java代码:
@Test public void testRabbitMq() throws Exception { RabbitTemplate rabbitTemplate = (RabbitTemplate) LeoContext.getContext().getApplication().getBean("rabbitTemplate"); //第二个参数为路由key(routingKey)的值,当路由可以为test321.hello.test123时,两个消费队列都可以收到消息,当值为test321.hello.aaa时,只有绑定了test321.#的队列才可以收到消息,当值为ta1.hello.test123,只有绑定了*.*.test123的队列才可收到消息 for(int i = 1; i <= 10; i++) { String str = "hello" + i; rabbitTemplate.send("leo.pay.topic.exchange", "test321.hello.test123", new Message(str.getBytes(), new MessageProperties())); } }
接收端(我配置的接收端与发送端不在同一个项目)spring的xml配置:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:task="http://www.springframework.org/schema/task" xmlns:rabbit="http://www.springframework.org/schema/rabbit" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.0.xsd http://www.springframework.org/schema/rabbit http://www.springframework.org/schema/rabbit/spring-rabbit-1.0.xsd" default-autowire="byName"> <!-- rabbitMQ配置 --> <bean id="rabbitConnectionFactory" class="org.springframework.amqp.rabbit.connection.CachingConnectionFactory"> <constructor-arg value="192.168.1.11"/> <property name="username" value="leo"/> <property name="password" value="lee31211"/> <property name="channelCacheSize" value="8"/> <property name="port" value="5672"></property> </bean> <rabbit:admin connection-factory="rabbitConnectionFactory"/> <rabbit:queue name="test123queue" durable="true" /> <rabbit:queue name="test321queue" durable="true" /> <!-- 该处是指将路由leo.pay.topic.exchange与两个队列绑定在一块,也可以在rabbitMq的控制台上手动绑定,手动绑定之后,该处代码可以省略,其实发送端已经绑定过了,也没必要绑定了,所以该代码可以省略 --> <!-- <rabbit:topic-exchange name="leo.pay.topic.exchange" xmlns="http://www.springframework.org/schema/rabbit" durable="true"> --> <!-- <bindings> --> <!-- <binding queue="test123queue" pattern="test123.*" /> --> <!-- <binding queue="test321queue" pattern="test321.*" /> --> <!-- </bindings> --> <!-- </rabbit:topic-exchange> --> <!-- 启动两个队列对应的监听(消费者) --> <bean id="detailQueueConsumer" class="com.leo.website.cousumer.DetailQueueConsumer"></bean> <bean id="testQueueConsumer" class="com.leo.website.cousumer.TestQueueConsumer"></bean> <!-- 将两个队列加入监听容器中,每个队列的监听都对应一个监听器 --> <rabbit:listener-container connection-factory="rabbitConnectionFactory" concurrency= "8"> <rabbit:listener queues="test123queue" ref="detailQueueConsumer" method="onMessage"/> <rabbit:listener queues="test321queue" ref="testQueueConsumer" method="onMessage"/> </rabbit:listener-container> </beans>
接收端java代码(只列出一个监听,另外一个类似):
public class DetailQueueConsumer implements MessageListener { @Override public void onMessage(Message message) { System.out.println("DetailQueueConsumer: " + new String(message.getBody())); } }

基于这个基础,我们需要做一定的修改,当接收端关闭时,rabbitMq中待发送消息无法到达,当接收端启动,listener会在启动过程中便已接收到消息进行业务处理,这样存在风险,我们可以做以下改动进行优化
public class MessageReceiver implements MessageListener{ private boolean startFlag = true; @Override public synchronized void onMessage(Message msg) { try{ //刚启动系统时,延迟30秒后执行 if(startFlag){ Thread.sleep(30000); startFlag = false; } System.out.println("topic.serviceMessageClientTempQueue : " + new String(msg.getBody(), "UTF-8")); } catch (Exception e) { e.printStackTrace(); } } }
