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
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
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
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

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");
}
}
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();
}
}
}
}
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");
}
}
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。
