RabbitMQ学习之spring整合发送异步消息

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.  

9. <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

10. <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />

11. <property name="ignoreResourceNotFound" value="true" />

12. <property name="locations">

13. <list>

14. <!-- 标准配置 -->

15. <value>classpath*:/application.properties</value>

16. </list>

17. </property>

18. </bean>

19.  

20. <!-- 创建connectionFactory -->

21. <bean id="rabbitConnectionFactory"

22. class="org.springframework.amqp.rabbit.connection.CachingConnectionFactory">

23. <constructor-arg value="${rabbit.hosts}"/>

24. <property name="username" value="${rabbit.username}"/>

25. <property name="password" value="${rabbit.password}"/>

26. <property name="virtualHost" value="${rabbit.virtualHost}"/>

27. <property name="channelCacheSize" value="5"/>

28. </bean>

29.  

30. <!-- 创建rabbitAdmin 代理类 -->

31. <bean id="rabbitAdmin"

32. class="org.springframework.amqp.rabbit.core.RabbitAdmin">

33. <constructor-arg ref="rabbitConnectionFactory" />

34. </bean>

35.  

36. <!-- 创建rabbitTemplate 消息模板类

37. -->

38. <bean id="rabbitTemplate"

39. class="org.springframework.amqp.rabbit.core.RabbitTemplate">

40. <constructor-arg ref="rabbitConnectionFactory"></constructor-arg>

41. <property name="routingKey" value="${rabbit.routingKey}"></property>

42. </bean>

43. </beans>

3.生产者发送消息代码Send.java

1. package cn.slimsmart.rabbitmq.demo.spring.async;

2.  

3. import org.springframework.amqp.core.AmqpTemplate;

4. import org.springframework.amqp.rabbit.core.RabbitTemplate;

5. import org.springframework.context.ApplicationContext;

6. import org.springframework.context.support.ClassPathXmlApplicationContext;

7.  

8. public class Send {

9.  

10. public static void main(String[] args) throws InterruptedException {

11. ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-rabbitmq-async-send.xml");

12. AmqpTemplate amqpTemplate = context.getBean(RabbitTemplate.class);

13. for(int i=0;i<1000;i++){

14. amqpTemplate.convertAndSend("test spring async=>"+i);

15. Thread.sleep(3000);

16. }

17. }

18. }

4.处理消息类ReceiveMsgHandler.java

1. package cn.slimsmart.rabbitmq.demo.spring.async;

2.  

3. public class ReceiveMsgHandler {

4.  

5. public void handleMessage(String text) {

6. System.out.println("Received: " + text);

7. }

8. }

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.  

9. <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

10. <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />

11. <property name="ignoreResourceNotFound" value="true" />

12. <property name="locations">

13. <list>

14. <!-- 标准配置 -->

15. <value>classpath*:/application.properties</value>

16. </list>

17. </property>

18. </bean>

19.  

20. <!-- 创建connectionFactory -->

21. <bean id="rabbitConnectionFactory"

22. class="org.springframework.amqp.rabbit.connection.CachingConnectionFactory">

23. <constructor-arg value="${rabbit.hosts}"/>

24. <property name="username" value="${rabbit.username}"/>

25. <property name="password" value="${rabbit.password}"/>

26. <property name="virtualHost" value="${rabbit.virtualHost}"/>

27. <property name="channelCacheSize" value="5"/>

28. </bean>

29.  

30. <!-- 声明消息转换器为SimpleMessageConverter -->

31. <bean id="messageConverter"

32. class="org.springframework.amqp.support.converter.SimpleMessageConverter">

33. </bean>

34. <!-- 监听生产者发送的消息开始 -->

35. <!-- 用于接收消息的处理类 -->

36. <bean id="receiveHandler"

37. class="cn.slimsmart.rabbitmq.demo.spring.async.ReceiveMsgHandler">

38. </bean>

39. <!-- 用于消息的监听的代理类MessageListenerAdapter -->

40. <bean id="receiveListenerAdapter"

41. class="org.springframework.amqp.rabbit.listener.adapter.MessageListenerAdapter">

42. <constructor-arg ref="receiveHandler" />

43. <property name="defaultListenerMethod" value="handleMessage"></property>

44. <property name="messageConverter" ref="messageConverter"></property>

45. </bean>

46. <!-- 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 -->

47. <bean id="listenerContainer"

48. class="org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer">

49. <property name="queueNames" value="${rabbit.queue}"></property>

50. <property name="connectionFactory" ref="rabbitConnectionFactory"></property>

51. <property name="messageListener" ref="receiveListenerAdapter"></property>

52. </bean>

53. <!-- 监听生产者发送的消息结束 -->

54. </beans>

5.接收消息启动类Receive.java

1. package cn.slimsmart.rabbitmq.demo.spring.async;

2.  

3. import org.springframework.context.support.ClassPathXmlApplicationContext;

4.  

5. public class Receive {

6.  

7. public static void main(String[] args) {

8. new ClassPathXmlApplicationContext("applicationContext-rabbitmq-async-receive.xml");

9. }

10. }

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。

1. log4j:WARN No appenders could be found for logger (org.springframework.core.env.StandardEnvironment).

2. log4j:WARN Please initialize the log4j system properly.
