（转） RabbitMQ学习之spring整合发送异步消息

http://blog.csdn.net/zhu_tianwei/article/details/40919031

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。
