<version>4.1.7.RELEASE</version>
</dependency>
<!-- spring整合jms -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jms</artifactId>
<version>4.1.7.RELEASE</version>
</dependency>
<!-- ActiveMQ的坐标 -->
<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-all</artifactId>
<version>5.2.0</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>4.1.7.RELEASE</version>

<!-- 使用ActiveMQ的时候,也要导入这个坐标 -->
<dependency>
<groupId>org.apache.xbean</groupId>

</dependencies>
二.配置applicationContext.xml

<!-- 指定Spring框架扫描的包 -->
<context:component-scan base-package="com.itheima.activemq" />
<!--
################################# 指定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
-->
<bean id="amqConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
<constructor-arg index="0" value="admin"></constructor-arg>
<constructor-arg index="1" value="admin"></constructor-arg>
<constructor-arg index="2" value="tcp://localhost:61616"></constructor-arg>
</bean>
<!-- 上面和下面两种方式是同样的效果 -->
<amq:connectionFactory id="xx" userName="admin"
password="admin" brokerURL="tcp://localhost:61616"></amq:connectionFactory>
<!--
################################# 指定Spring Caching连接工厂 #################################
-->

<!-- 目标ConnectionFactory对应真实的可以产生JMS Connection的ConnectionFactory -->
<property name="targetConnectionFactory" ref="xx"></property>

</bean>
<!--
################################# 指定消息的生产者 #################################
-->
<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" />
<!-- 定义JmsTemplate的Queue类型 -->

<property name="pubSubDomain" value="false" />
</bean>
<!--

acknowledge="auto">
<!-- destination : 消息队列的名字 -->
<!-- ref : 消息的消费者 -->
<jms:listener destination="test.queue" ref="consumer" />
</jms:listener-container>
</beans>
三.开发生产者
3.1生产者一
@Component
public class Producer {
@Autowired
private JmsTemplate jmsTemplate;
public void sendMessage(String destinationName, final String message) {
// destinationName : 消息队列的名字,要把这个消息发送到那一个队列
jmsTemplate.send(destinationName, new MessageCreator() {
@Override
public Message createMessage(Session session) throws JMSException {
TextMessage textMessage = session.createTextMessage(message);
return textMessage;
}
});
}
}
3.2生产者二:
@Autowired
private JmsTemplate jmsTemplate;
方法体里面增加:
// 通過中間件來發送信息;
jmsTemplate.send("sms-message", new MessageCreator() {
// 参数1:消息队列的名称
// 参数2:创建消息的对象
@Override
public Message createMessage(Session session) throws JMSException {
MapMessage mapMessage = session.createMapMessage();
mapMessage.setString("telephone", model.getTelephone());
mapMessage.setString("msg", msg);
return mapMessage;
}
});
3.3生产者三
@Autowired
private JmsTemplate jmsTemplate;
方法体里面增加:
// 通過中間件來發送郵件
jmsTemplate.send("email-message", new MessageCreator() {
@Override
public Message createMessage(Session session) throws JMSException {
MapMessage mapMessage = session.createMapMessage();
mapMessage.setString("email", model.getEmail());
mapMessage.setString("theme", "激活邮件");
mapMessage.setString("msg", msg);
return mapMessage;
}
});
四.开发消费者
4.1消费者一:
@Component
public class Consumer implements MessageListener {
@Override
public void onMessage(Message message) {
try {
TextMessage textMessage = (TextMessage) message;
String text = textMessage.getText();
System.out.println(text);
} catch (JMSException e) {
e.printStackTrace();
}
}
}
4.2消费者二(邮件发送)
@Component
public class EmailConsumer implements MessageListener {
@Override
public void onMessage(Message message) {
MapMessage mapMessage=(MapMessage) message;
try {
String email = mapMessage.getString("email");
String theme = mapMessage.getString("theme");
String msg = mapMessage.getString("msg");
MailUtils.sendMail(email,theme, msg);
} catch (JMSException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
4.3消费者三(短信发送)
@Component
public class SmsConsumer implements MessageListener{
@Override
public void onMessage(Message message) {
MapMessage mapMessage = (MapMessage) message;
try {
String telephone = mapMessage.getString("telephone");
String msg = mapMessage.getString("msg");
System.out.println(telephone+"======"+msg);
SmsUtils.sendSmsByWebService(telephone, msg);
} catch (JMSException e) {
e.printStackTrace();
}
}
}
