1. 集成环境
Spring采用2.5.6版本,ActiveMQ使用的是5.4.2,从apache站点可以下载。本文是将Spring集成ActiveMQ来发送和接收JMS消息。
2. 集成步骤
将下载的ActiveMQ解压缩后文件夹如下
activemq-all-5.4.2.jar是activemq的所有的类jar包。lib下面是模块分解后的jar包。将lib下面的
/lib/activation-1.1.jar /lib/activemq-camel-5.4.2.jar /lib/activemq-console-5.4.2.jar /lib/activemq-core-5.4.2.jar /lib/activemq-jaas-5.4.2.jar /lib/activemq-pool-5.4.2.jar /lib/activemq-protobuf-1.1.jar /lib/activemq-spring-5.4.2.jar /lib/activemq-web-5.4.2.jar
/lib/activation-1.1.jar /lib/activemq-camel-5.4.2.jar /lib/activemq-console-5.4.2.jar /lib/activemq-core-5.4.2.jar /lib/activemq-jaas-5.4.2.jar /lib/activemq-pool-5.4.2.jar /lib/activemq-protobuf-1.1.jar /lib/activemq-spring-5.4.2.jar /lib/activemq-web-5.4.2.jar
/lib/activation-1.1.jar /lib/activemq-camel-5.4.2.jar /lib/activemq-console-5.4.2.jar /lib/activemq-core-5.4.2.jar /lib/activemq-jaas-5.4.2.jar /lib/activemq-pool-5.4.2.jar /lib/activemq-protobuf-1.1.jar /lib/activemq-spring-5.4.2.jar /lib/activemq-web-5.4.2.jar
文件全部拷贝到项目中。
而Spring项目所需要的jar包如下
/lib/spring-beans-2.5.6.jar /lib/spring-context-2.5.6.jar /lib/spring-context-support-2.5.6.jar /lib/spring-core-2.5.6.jar /lib/spring-jms-2.5.6.jar /lib/spring-tx.jar
/lib/spring-beans-2.5.6.jar /lib/spring-context-2.5.6.jar /lib/spring-context-support-2.5.6.jar /lib/spring-core-2.5.6.jar /lib/spring-jms-2.5.6.jar /lib/spring-tx.jar
/lib/spring-beans-2.5.6.jar /lib/spring-context-2.5.6.jar /lib/spring-context-support-2.5.6.jar /lib/spring-core-2.5.6.jar /lib/spring-jms-2.5.6.jar /lib/spring-tx.jar
当然还需要一些其他的jar文件
/lib/geronimo-j2ee-management_1.1_spec-1.0.1.jar /lib/jms-1.1.jar /lib/log4j-1.2.15.jar /lib/slf4j-api-1.6.1.jar /lib/slf4j-nop-1.6.1.jar
/lib/geronimo-j2ee-management_1.1_spec-1.0.1.jar /lib/jms-1.1.jar /lib/log4j-1.2.15.jar /lib/slf4j-api-1.6.1.jar /lib/slf4j-nop-1.6.1.jar
/lib/geronimo-j2ee-management_1.1_spec-1.0.1.jar /lib/jms-1.1.jar /lib/log4j-1.2.15.jar /lib/slf4j-api-1.6.1.jar /lib/slf4j-nop-1.6.1.jar
项目的依赖jar都准备好后就可以写配置文件了。
Spring配置文件
配置文件内容如下

编写代码
消息发送者:这里面消息生产者并没有在Spring配置文件中进行配置,这里仅仅使用了Spring中的JMS模板和消息目的而已。
public class HelloSender { /** * @param args */ public static void main(String[] args) { ApplicationContext applicationContext = new ClassPathXmlApplicationContext( new String[] { "classpath:/spring/applicationContext-jms.xml" }); JmsTemplate template = (JmsTemplate) applicationContext .getBean("jmsTemplate"); Destination destination = (Destination) applicationContext .getBean("destination"); template.send(destination, new MessageCreator() { public Message createMessage(Session session) throws JMSException { return session .createTextMessage("发送消息:Hello ActiveMQ Text Message!"); } }); System.out.println("成功发送了一条JMS消息"); } }
public class HelloSender { /** * @param args */ public static void main(String[] args) { ApplicationContext applicationContext = new ClassPathXmlApplicationContext( new String[] { "classpath:/spring/applicationContext-jms.xml" }); JmsTemplate template = (JmsTemplate) applicationContext .getBean("jmsTemplate"); Destination destination = (Destination) applicationContext .getBean("destination"); template.send(destination, new MessageCreator() { public Message createMessage(Session session) throws JMSException { return session .createTextMessage("发送消息:Hello ActiveMQ Text Message!"); } }); System.out.println("成功发送了一条JMS消息"); } }
public class HelloSender { /** * @param args */ public static void main(String[] args) { ApplicationContext applicationContext = new ClassPathXmlApplicationContext( new String[] { "classpath:/spring/applicationContext-jms.xml" }); JmsTemplate template = (JmsTemplate) applicationContext .getBean("jmsTemplate"); Destination destination = (Destination) applicationContext .getBean("destination"); template.send(destination, new MessageCreator() { public Message createMessage(Session session) throws JMSException { return session .createTextMessage("发送消息:Hello ActiveMQ Text Message!"); } }); System.out.println("成功发送了一条JMS消息"); } }
消息接收
/** * JMS消费者 * * * <p> * 消息题的内容定义 * <p> * 消息对象 接收消息对象后: 接收到的消息体* <p> */ public class ProxyJMSConsumer { public ProxyJMSConsumer() { } private JmsTemplate jmsTemplate; public JmsTemplate getJmsTemplate() { return jmsTemplate; } public void setJmsTemplate(JmsTemplate jmsTemplate) { this.jmsTemplate = jmsTemplate; } /** * 监听到消息目的有消息后自动调用onMessage(Message message)方法 */ public void recive() { ApplicationContext applicationContext = new ClassPathXmlApplicationContext( new String[] { "classpath:/spring/applicationContext-jms.xml" }); Destination destination = (Destination) applicationContext .getBean("destination"); while (true) { try { TextMessage txtmsg = (TextMessage) jmsTemplate .receive(destination); if (null != txtmsg) { System.out.println("[DB Proxy] " + txtmsg); System.out.println("[DB Proxy] 收到消息内容为: " + txtmsg.getText()); } else break; } catch (Exception e) { e.printStackTrace(); } } } }
/** * JMS消费者 * * * <p> * 消息题的内容定义 * <p> * 消息对象 接收消息对象后: 接收到的消息体* <p> */ public class ProxyJMSConsumer { public ProxyJMSConsumer() { } private JmsTemplate jmsTemplate; public JmsTemplate getJmsTemplate() { return jmsTemplate; } public void setJmsTemplate(JmsTemplate jmsTemplate) { this.jmsTemplate = jmsTemplate; } /** * 监听到消息目的有消息后自动调用onMessage(Message message)方法 */ public void recive() { ApplicationContext applicationContext = new ClassPathXmlApplicationContext( new String[] { "classpath:/spring/applicationContext-jms.xml" }); Destination destination = (Destination) applicationContext .getBean("destination"); while (true) { try { TextMessage txtmsg = (TextMessage) jmsTemplate .receive(destination); if (null != txtmsg) { System.out.println("[DB Proxy] " + txtmsg); System.out.println("[DB Proxy] 收到消息内容为: " + txtmsg.getText()); } else break; } catch (Exception e) { e.printStackTrace(); } } } }
/** * JMS消费者 * * * <p> * 消息题的内容定义 * <p> * 消息对象 接收消息对象后: 接收到的消息体* <p> */ public class ProxyJMSConsumer { public ProxyJMSConsumer() { } private JmsTemplate jmsTemplate; public JmsTemplate getJmsTemplate() { return jmsTemplate; } public void setJmsTemplate(JmsTemplate jmsTemplate) { this.jmsTemplate = jmsTemplate; } /** * 监听到消息目的有消息后自动调用onMessage(Message message)方法 */ public void recive() { ApplicationContext applicationContext = new ClassPathXmlApplicationContext( new String[] { "classpath:/spring/applicationContext-jms.xml" }); Destination destination = (Destination) applicationContext .getBean("destination"); while (true) { try { TextMessage txtmsg = (TextMessage) jmsTemplate .receive(destination); if (null != txtmsg) { System.out.println("[DB Proxy] " + txtmsg); System.out.println("[DB Proxy] 收到消息内容为: " + txtmsg.getText()); } else break; } catch (Exception e) { e.printStackTrace(); } } } }
这里边也是并不是直接使用Spring来初始化建立消息消费者实例,而是在此消费者注入了JMS模板而已。
写一个main入口,初始化消息消费者
public class JMSTest { /** * @param args */ public static void main(String[] args) { ApplicationContext applicationContext = new ClassPathXmlApplicationContext( new String[] { "classpath:/spring/applicationContext-jms.xml" }); ProxyJMSConsumer proxyJMSConsumer = (ProxyJMSConsumer) applicationContext .getBean("messageReceiver"); System.out.println("初始化消息消费者"); } }
public class JMSTest { /** * @param args */ public static void main(String[] args) { ApplicationContext applicationContext = new ClassPathXmlApplicationContext( new String[] { "classpath:/spring/applicationContext-jms.xml" }); ProxyJMSConsumer proxyJMSConsumer = (ProxyJMSConsumer) applicationContext .getBean("messageReceiver"); System.out.println("初始化消息消费者"); } }
public class JMSTest { /** * @param args */ public static void main(String[] args) { ApplicationContext applicationContext = new ClassPathXmlApplicationContext( new String[] { "classpath:/spring/applicationContext-jms.xml" }); ProxyJMSConsumer proxyJMSConsumer = (ProxyJMSConsumer) applicationContext .getBean("messageReceiver"); System.out.println("初始化消息消费者"); } }
使用的时候先开启ActiveMQ服务,默认是占用了61616端口。之后开启测试程序,开启2个消息消费者监听。之后再运行消息生产者的代码后,消息就可以被消息消费者接收到了。
