实现使用Exchange类型为DirectExchange. routingkey的名称默认为Queue的名称。异步发送消息。

1.配置文件

  1. #============== rabbitmq config ====================
  2. rabbit.hosts=192.168.36.102
  3. rabbit.username=admin
  4. rabbit.password=admin
  5. rabbit.virtualHost=/
  6. rabbit.queue=spring-queue-async
  7. rabbit.routingKey=spring-queue-async#<span style="font-family: Helvetica, Tahoma, Arial, sans-serif; font-size: 14px; line-height: 25.2000007629395px;">routingkey的名称默认为Queue的名称</span>

2.生产者配置applicationContext-rabbitmq-async-send.xml：

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3. xmlns:context="http://www.springframework.org/schema/context"
  4. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  5. xsi:schemaLocation="
  6. http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
  7. http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">
  8. <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
  9. <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
  10. <property name="ignoreResourceNotFound" value="true" />
  11. <property name="locations">
  12. <list>
  13. <!-- 标准配置 -->
  14. <value>classpath*:/application.properties</value>
  15. </list>
  16. </property>
  17. </bean>
  18. <!-- 创建connectionFactory -->
  19. <bean id="rabbitConnectionFactory"
  20. class="org.springframework.amqp.rabbit.connection.CachingConnectionFactory">
  21. <constructor-arg value="${rabbit.hosts}"/>
  22. <property name="username" value="${rabbit.username}"/>
  23. <property name="password" value="${rabbit.password}"/>
  24. <property name="virtualHost" value="${rabbit.virtualHost}"/>
  25. <property name="channelCacheSize" value="5"/>
  26. </bean>
  27. <!-- 创建rabbitAdmin 代理类 -->
  28. <bean id="rabbitAdmin"
  29. class="org.springframework.amqp.rabbit.core.RabbitAdmin">
  30. <constructor-arg ref="rabbitConnectionFactory" />
  31. </bean>
  32. <!-- 创建rabbitTemplate 消息模板类
  33. -->
  34. <bean id="rabbitTemplate"
  35. class="org.springframework.amqp.rabbit.core.RabbitTemplate">
  36. <constructor-arg ref="rabbitConnectionFactory"></constructor-arg>
  37. <property name="routingKey" value="${rabbit.routingKey}"></property>
  38. </bean>
  39. </beans>

3.生产者发送消息代码Send.java

  1. package cn.slimsmart.rabbitmq.demo.spring.async;
  2. import org.springframework.amqp.core.AmqpTemplate;
  3. import org.springframework.amqp.rabbit.core.RabbitTemplate;
  4. import org.springframework.context.ApplicationContext;
  5. import org.springframework.context.support.ClassPathXmlApplicationContext;
  6. public class Send {
  7. public static void main(String[] args) throws InterruptedException {
  8. ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-rabbitmq-async-send.xml");
  9. AmqpTemplate amqpTemplate = context.getBean(RabbitTemplate.class);
  10. for(int i=0;i<1000;i++){
  11. amqpTemplate.convertAndSend("test spring async=>"+i);
  12. Thread.sleep(3000);
  13. }
  14. }
  15. }

4.处理消息类ReceiveMsgHandler.Java

  1. package cn.slimsmart.rabbitmq.demo.spring.async;
  2. public class ReceiveMsgHandler {
  3. public void handleMessage(String text) {
  4. System.out.println("Received: " + text);
  5. }
  6. }

5.配置applicationContext-rabbitmq-async-receive.xml：

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3. xmlns:context="http://www.springframework.org/schema/context"
  4. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  5. xsi:schemaLocation="
  6. http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
  7. http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">
  8. <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
  9. <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
  10. <property name="ignoreResourceNotFound" value="true" />
  11. <property name="locations">
  12. <list>
  13. <!-- 标准配置 -->
  14. <value>classpath*:/application.properties</value>
  15. </list>
  16. </property>
  17. </bean>
  18. <!-- 创建connectionFactory -->
  19. <bean id="rabbitConnectionFactory"
  20. class="org.springframework.amqp.rabbit.connection.CachingConnectionFactory">
  21. <constructor-arg value="${rabbit.hosts}"/>
  22. <property name="username" value="${rabbit.username}"/>
  23. <property name="password" value="${rabbit.password}"/>
  24. <property name="virtualHost" value="${rabbit.virtualHost}"/>
  25. <property name="channelCacheSize" value="5"/>
  26. </bean>
  27. <!-- 声明消息转换器为SimpleMessageConverter -->
  28. <bean id="messageConverter"
  29. class="org.springframework.amqp.support.converter.SimpleMessageConverter">
  30. </bean>
  31. <!-- 监听生产者发送的消息开始 -->
  32. <!-- 用于接收消息的处理类 -->
  33. <bean id="receiveHandler"
  34. class="cn.slimsmart.rabbitmq.demo.spring.async.ReceiveMsgHandler">
  35. </bean>
  36. <!-- 用于消息的监听的代理类MessageListenerAdapter -->
  37. <bean id="receiveListenerAdapter"
  38. class="org.springframework.amqp.rabbit.listener.adapter.MessageListenerAdapter">
  39. <constructor-arg ref="receiveHandler" />
  40. <property name="defaultListenerMethod" value="handleMessage"></property>
  41. <property name="messageConverter" ref="messageConverter"></property>
  42. </bean>
  43. <!-- 用于消息的监听的容器类SimpleMessageListenerContainer，对于queueName的值一定要与定义的Queue的值相同 -->
  44. <bean id="listenerContainer"
  45. class="org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer">
  46. <property name="queueNames" value="${rabbit.queue}"></property>
  47. <property name="connectionFactory" ref="rabbitConnectionFactory"></property>
  48. <property name="messageListener" ref="receiveListenerAdapter"></property>
  49. </bean>
  50. <!-- 监听生产者发送的消息结束 -->
  51. </beans>

5.接收消息启动类Receive.java

  1. package cn.slimsmart.rabbitmq.demo.spring.async;
  2. import org.springframework.context.support.ClassPathXmlApplicationContext;
  3. public class Receive {
  4. public static void main(String[] args) {
  5. new ClassPathXmlApplicationContext("applicationContext-rabbitmq-async-receive.xml");
  6. }
  7. }

启动接收消息，再发送消息

  1. Received: test spring async=>0
  2. Received: test spring async=>1
  3. Received: test spring async=>2
  4. Received: test spring async=>3
  5. Received: test spring async=>4
  6. Received: test spring async=>5
  7. Received: test spring async=>6
  8. Received: test spring async=>7
  9. ......

若报如下错误，说明消息队列不存在，请在控制台添加消息队列。
