新增pom.xml
<dependency> <groupId>org.apache.activemq</groupId> <artifactId>activemq-all</artifactId> <version>5.11.2</version> </dependency> <!-- activeMQ和spring整合 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jms</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> </dependency>
建立applicationContext-activemq.xml

建立測試生產者
@Test public void testSpringActiveMq() throws Exception { //初始化spring容器 ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:spring/applicationContext-activemq.xml"); //從spring容器中獲得JmsTemplate物件 JmsTemplate jmsTemplate = applicationContext.getBean(JmsTemplate.class); //從spring容器中取Destination物件 Destination destination = (Destination) applicationContext.getBean("queueDestination"); //使用JmsTemplate物件傳送訊息。 jmsTemplate.send(destination, new MessageCreator() { @Override public Message createMessage(Session session) throws JMSException { //建立一個訊息物件並返回 TextMessage textMessage = session.createTextMessage("spring activemq queue message"); return textMessage; } }); }
接收方
在需要接收訊息的服務中配置applicationContext-activemq.xml，並新增上訴依賴

</bean>
<!--這個是主題目的地，一對多的 -->
<bean id="topicDestination" class="org.apache.activemq.command.ActiveMQTopic">

</beans>建立MyMessageListener
public class MyMessageListener implements MessageListener{
@Override
public void onMessage(Message message) {
try {
TextMessage textMessage = (TextMessage) message;
String text = null;
//取訊息的內容
text = textMessage.getText();
// 第八步：列印訊息。
System.out.println(text);
} catch (JMSException e) {
e.printStackTrace();
}
}
}
建立接收測試類
@Test
public void testQueueConsumer() throws Exception {
//初始化spring容器
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:spring/applicationContext-activemq.xml");
//等待
System.in.read();
}
