解压启动bin\activemq.bat

生产者接口：

public interface ProducerService {    /**     * 向指定队列发送消息     */    void sendMessage(Destination destination, final String msg);    /**     * 向默认队列发送消息     */    void sendMessage(final String msg);}

消费者接口：

public interface ConsumerService {    /**     * 接受消息     */    void receive(Destination destination);}

生产者实现：

@Service("producerService")public class ProducerServiceImpl implements ProducerService {    @Resource    private JmsTemplate jmsTemplate;    /**     * 向指定队列发送消息     */    public void sendMessage(Destination destination, final String msg) {        System.out.println("向队列" + destination.toString() + "发送了消息------------" + msg);        jmsTemplate.send(destination, new MessageCreator() {            public Message createMessage(Session session) throws JMSException {                return session.createTextMessage(msg);            }        });    }    /**     * 向默认队列发送消息     */    public void sendMessage(final String msg) {        String destination =  jmsTemplate.getDefaultDestination().toString();        System.out.println("向队列" +destination+ "发送了消息------------" + msg);        jmsTemplate.send(new MessageCreator() {            public Message createMessage(Session session) throws JMSException {                return session.createTextMessage(msg);            }        });    }}

消费者实现：

@Service("consumerService")public class ConsumerServiceImpl implements ConsumerService {    @Resource    private JmsTemplate jmsTemplate;    /**     * 接受消息     */    public void receive(Destination destination) {        TextMessage tm = (TextMessage) jmsTemplate.receive(destination);        try {            System.out.println("从队列" + destination.toString() + "收到了消息：\t"                    + tm.getText());        } catch (JMSException e) {            e.printStackTrace();        }    }}

测试：

@Testpublic void producerTest(){    // 加载spring    ClassPathXmlApplicationContext springContext = SpringContainer.getSpringContext();    ProducerService producerService = (ProducerService)springContext.getBean("producerService");    ConsumerService consumerService = (ConsumerService)springContext.getBean("consumerService");    Destination destination = (Destination)springContext.getBean("queueDestination");    producerService.sendMessage("测试消息队列");    consumerService.receive(destination);}

public class SpringContainer {    public static final String DEFAULT_SPRING_CONFIG = "classpath:META-INF/spring/*.xml";    public static ClassPathXmlApplicationContext getSpringContext() {        return MySpringContainer.context;    }    private static class MySpringContainer{        private static ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(DEFAULT_SPRING_CONFIG.split("[,\\s]+"));    }}
