ActiveMQ_Topic队列(三)

一、本文章包含的内容

1、列举了ActiveMQ中通过Topic方式发送、消费队列的代码（监听者有两个，分别是topicMessageListener1、topicMessageListener2）

2、spring+activemq方式

 

 

 

二、配置信息

1、activemq的pom.xml信息

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

<!--activemq  Begin-->        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-jms</artifactId>            <version>${spring.version}</version>        </dependency>        <!-- <dependency>             <groupId>org.springframework</groupId>             <artifactId>spring-messaging</artifactId>             <version>${spring.version}</version>         </dependency>-->        <dependency>            <groupId>org.apache.activemq</groupId>            <artifactId>activemq-all</artifactId>            <version>5.14.0</version>        </dependency>        <!--activemq  End-->

 

2、activemq的配置文件：spring-jms.xml

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49

<!-- 启用spring mvc 注解 -->    <context:component-scan base-package="org.soa.test.activemq"/>      <!-- 配置JMS连接工厂 -->    <bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">        <property name="brokerURL" value="failover:(tcp://192.168.146.129:61616)" />        <!--解决接收消息抛出异常：javax.jms.JMSException: Failed to build body from content.

三、队列发送端及测试程序

1、发送代码

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39

package org.soa.test.activemq.topics;   import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.jms.core.JmsTemplate; import org.springframework.jms.core.MessageCreator; import org.springframework.stereotype.Component;   import javax.jms.Destination; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.Session;   /**  * Created by JamesC on 16-9-22.  */ @Component public class TopicProvider {       @Autowired     @Qualifier("jmsTemplateTopic")     private JmsTemplate topicJmsTemplate;       /**      * 向指定的topic发布消息      *      * @param topic      * @param msg      */     public void publish(final Destination topic, final String msg) {         topicJmsTemplate.send(topic, new MessageCreator() {             public Message createMessage(Session session) throws JMSException {                 System.out.println("topic name 是" + topic.toString() + "，发布消息内容为:\t" + msg);                 return session.createTextMessage(msg);             }         });     }   }

2、监听代码

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55

//TopicMessageListener1 package org.soa.test.activemq.topics;   import org.springframework.stereotype.Component;   import javax.jms.JMSException; import javax.jms.Message; import javax.jms.MessageListener; import javax.jms.TextMessage;   /**  * Created by JamesC on 16-9-22.  */ @Component public class TopicMessageListener1 implements MessageListener {       public void onMessage(Message message) {         TextMessage tm = (TextMessage) message;         try {             System.out.println("TopicMessageListener_1 \t" + tm.getText());         } catch (JMSException e) {             e.printStackTrace();         }     } }           //TopicMessageListener2 package org.soa.test.activemq.topics;   import org.springframework.stereotype.Component;   import javax.jms.JMSException; import javax.jms.Message; import javax.jms.MessageListener; import javax.jms.TextMessage;   /**  * Created by JamesC on 16-9-22.  */ @Component public class TopicMessageListener2 implements MessageListener {       public void onMessage(Message message) {         TextMessage tm = (TextMessage) message;         try {             System.out.println("TopicMessageListener_2 \t" + tm.getText());         } catch (JMSException e) {             e.printStackTrace();         }     } }

3、测试程序

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35

package org.soa.test.activemq.topics;   import org.apache.activemq.command.ActiveMQQueue; import org.apache.activemq.command.ActiveMQTopic; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;   import javax.jms.Destination;   /**  * Created by JamesC on 16-9-22.  */ @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration("/spring-jms.xml") public class TopicTest {         @Autowired     private Destination queueDestination;       @Autowired     private TopicProvider provider;       //向默认Topic发消息     @Test     public void send() {         //坑爹的是：这里不要用ActiveMQQueue，会默认按Queue发送；要使用ActiveMQTopic，按Topic发送         //ActiveMQQueue des = new ActiveMQQueue("topic1");         ActiveMQTopic des = new ActiveMQTopic("topic1");         provider.publish(des,"topic消息示例");     } }
