消息中间件ActiveMQ的简单使用-Spring整合开发(1)

1.引入Spring整合ActivwMQ开发的maven坐标

<!-- spring 与 mq整合 start -->
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-jms</artifactId>
			<version>4.2.4.RELEASE</version>
		</dependency>
		<dependency>
			<groupId>org.apache.xbean</groupId>
			<artifactId>xbean-spring</artifactId>
			<version>3.7</version>
		</dependency>
		<!-- spring 与 mq整合 end -->

2.手动方式的spring配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

	xmlns:jpa="http://www.springframework.org/schema/data/jpa" xmlns:task="http://www.springframework.org/schema/task"
	xmlns:amq="http://activemq.apache.org/schema/core"

        http://www.springframework.org/schema/jms/spring-jms.xsd
		http://activemq.apache.org/schema/core
        http://activemq.apache.org/schema/core/activemq-core.xsd">
	
	<!-- 扫描包 -->
	<!-- <context:component-scan base-package="cn.itcast.jms" /> -->
	
	<!-- ActiveMQ 连接工厂 -->
    <!-- 真正可以产生Connection的ConnectionFactory，由对应的 JMS服务厂商提供-->
    <!-- 如果连接网络：tcp://ip:61616；未连接网络：tcp://localhost:61616 以及用户名，密码-->
    <amq:connectionFactory id="amqConnectionFactory"
        brokerURL="tcp://localhost:61616" userName="admin" password="admin"  />

    <!-- Spring Caching连接工厂 -->
    <!-- Spring用于管理真正的ConnectionFactory的ConnectionFactory -->  
    <bean id="connectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory">
        <!-- 目标ConnectionFactory对应真实的可以产生JMS Connection的ConnectionFactory -->  
        <property name="targetConnectionFactory" ref="amqConnectionFactory"></property>
        <!-- Session缓存数量和链接数有关 -->
        <property name="sessionCacheSize" value="100" />
    </bean>
    
     <!-- 定义JmsTemplate的Queue类型 -->
    <bean id="jmsQueueTemplate" class="org.springframework.jms.core.JmsTemplate">
        <!-- 这个connectionFactory对应的是我们定义的Spring提供的那个ConnectionFactory对象 -->  
        <constructor-arg ref="connectionFactory" />
        <!-- 非pub/sub模型（发布/订阅），即队列模式 -->
        <property name="pubSubDomain" value="false" />
    </bean>

    <!-- 定义JmsTemplate的Topic类型 -->
    <bean id="jmsTopicTemplate" class="org.springframework.jms.core.JmsTemplate" >
         <!-- 这个connectionFactory对应的是我们定义的Spring提供的那个ConnectionFactory对象 -->  
        <constructor-arg ref="connectionFactory" />
        <!-- pub/sub模型（发布/订阅） -->
        <property name="pubSubDomain" value="true"  />
    </bean>
</beans>

3.编写测试类

1).Queue模式下手动方式

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext-mq.xml")
public class SpringQueueTest {

	@Autowired
	@Qualifier(value="jmsQueueTemplate")
	private JmsTemplate queueTemplate;
	
	@Test
	public void testQueueSend() {
		queueTemplate.send("queue_test", new MessageCreator() {
			
			@Override
			public Message createMessage(Session session) throws JMSException {
				TextMessage message = session.createTextMessage("spring发送的消息");
				return message;
			}
		});
	}
	
	@Test
	public void testQueueReceive() throws JMSException {
		TextMessage message = (TextMessage) queueTemplate.receive("queue_test");
		System.out.println(message.getText());
	}
}

2).Topic模式下手动方式

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext-mq.xml")
public class SpringTopicTest {

	@Autowired
	@Qualifier(value="jmsTopicTemplate")
	private JmsTemplate topicTemplate;
	
	@Test
	public void testTopicSend() {
		topicTemplate.send("topic_test",new MessageCreator() {
			
			@Override
			public Message createMessage(Session session) throws JMSException {
				MapMessage map = session.createMapMessage();
				map.setString("username", "admin");
				return map;
			}
		});
	}
	
	@Test
	public void testTopicReceive() throws JMSException {
		MapMessage message = (MapMessage) topicTemplate.receive("topic_test");
		System.out.println(message.getString("username"));
	}
}

注意：topic模式调用方法要先开启，在开启发送消息方法
