JMS 之 Active MQ 的spring整合

一、与spring整合实现ptp的同步接收消息

pom.xml:

   <!-- https://mvnrepository.com/artifact/org.springframework/spring-jms -->
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-jms</artifactId>
        <version>4.3.7.RELEASE</version>
    </dependency>
  <!-- https://mvnrepository.com/artifact/org.apache.activemq/activemq-pool -->
    <dependency>
        <groupId>org.apache.activemq</groupId>
        <artifactId>activemq-pool</artifactId>
        <version>5.9.0</version>
    </dependency>

spring-jms.xml:

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

<!-- ActiveMQConnectionFactory就是JMS中负责创建到ActiveMQ连接的工厂类 -->
<bean id="connectionFactory" class="org.apache.activemq.spring.ActiveMQConnectionFactory" >
     <property name="brokerURL" value="tcp://192.168.0.224:61616"/>  
</bean>
<!-- 创建连接池 -->
<bean id="pooledConnectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory" destroy-method="stop">  
    <property name="connectionFactory" ref="connectionFactory"/>  
    <property name="maxConnections" value="10"/>  
</bean>  
<!-- Spring为我们提供了多个ConnectionFactory,有SingleConnectionFactory和CachingConnectionFactory -->
<bean id="cachingConnectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory">  
    <property name="targetConnectionFactory" ref="pooledConnectionFactory"/>  
</bean> 

<!-- Spring提供的JMS工具类,它可以进行消息发送、接收等 -->  
<bean id="jmsTemplate" 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 -->  
    <property name="connectionFactory" ref="cachingConnectionFactory"/>  
</bean> 

<!--这个是队列目的地,点对点的-->  
<bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">  
    <constructor-arg index="0" value="spring-queue"/> 
</bean>   

</beans> 

   ConnectionFactory是用于产生到JMS服务器的链接的,Spring为我们提供了多个ConnectionFactory,有SingleConnectionFactory和CachingConnectionFactory。SingleConnectionFactory对于建立JMS服务器链接的请求会一直返回同一个链接,并且会忽略Connection的close方法调用。CachingConnectionFactory继承了SingleConnectionFactory,所以它拥有SingleConnectionFactory的所有功能,同时它还新增了缓存功能,它可以缓存Session、MessageProducer和MessageConsumer。这里我们使用CachingConnectionFactory来作为示例。

消息生产者:

package com.jalja.org.jms.spring;

import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Session;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;

public class SpringJmsSend {
    public static void main(String[] args) {
        ApplicationContext context=new ClassPathXmlApplicationContext("spring-jms.xml");
        JmsTemplate jmsTemplate=(JmsTemplate) context.getBean("jmsTemplate");
        Destination queueDestination=(Destination) context.getBean("queueDestination");
        jmsTemplate.send(queueDestination, new MessageCreator(){
            @Override
            public Message createMessage(Session session) throws JMSException {
                return session.createTextMessage("Hello spring JMS");
            }
        });
    }
}

消费者:

package com.jalja.org.jms.spring;

import javax.jms.Destination;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;

public class SpringJmsReceive {
public static void main(String[] args) {
    ApplicationContext context=new ClassPathXmlApplicationContext("spring-jms.xml");
    JmsTemplate jmsTemplate=(JmsTemplate) context.getBean("jmsTemplate");
    Destination queueDestination=(Destination) context.getBean("queueDestination");
    String msg=(String) jmsTemplate.receiveAndConvert(queueDestination);
    System.out.println(msg);
  }
}

二、PTP的异步调用

 我们在spring中直接配置异步接收消息的监听器,这样就相当于在spring中配置了消费者,在接受消息的时候就不必要启动消费者了。

spring-jms.xml:

<?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:jms="http://www.springframework.org/schema/jms"
xmlns:amq="http://activemq.apache.org/schema/core"
xsi:schemaLocation="http://activemq.apache.org/schema/core
http://activemq.apache.org/schema/core/activemq-core.xsd
http://www.springframework.org/schema/jms
http://www.springframework.org/schema/jms/spring-jms.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">

<!-- ActiveMQConnectionFactory就是JMS中负责创建到ActiveMQ连接的工厂类 -->
<bean id="connectionFactory" class="org.apache.activemq.spring.ActiveMQConnectionFactory" >
     <property name="brokerURL" value="tcp://192.168.0.224:61616"/>  
</bean>
<!-- 创建连接池 -->
<bean id="pooledConnectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory" destroy-method="stop">  
    <property name="connectionFactory" ref="connectionFactory"/>  
    <property name="maxConnections" value="10"/>  
</bean>  
<!-- Spring为我们提供了多个ConnectionFactory,有SingleConnectionFactory和CachingConnectionFactory -->
<bean id="cachingConnectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory">  
    <property name="targetConnectionFactory" ref="pooledConnectionFactory"/>  
</bean> 

<!-- Spring提供的JMS工具类,它可以进行消息发送、接收等 -->  
<bean id="jmsTemplate" 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 -->  
    <property name="connectionFactory" ref="cachingConnectionFactory"/>  
</bean> 

<!--这个是队列目的地,点对点的-->  
<bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">  
    <constructor-arg index="0" value="spring-queue"/> 
</bean>   

<!-- 消息监听器 -->  
<bean id="myMessageListener" class="com.jalja.org.jms.spring.yb.MyMessageListener"/>  

<!-- 消息监听容器 -->  
<bean id="jmsContainer"  class="org.springframework.jms.listener.DefaultMessageListenerContainer">  
    <property name="connectionFactory" ref="cachingConnectionFactory" />  
    <property name="destination" ref="queueDestination" />  
    <property name="messageListener" ref="myMessageListener" />  
</bean> 
</beans> 

  生产者往指定目的地Destination发送消息后,接下来就是消费者对指定目的地的消息进行消费了。那么消费者是如何知道有生产者发送消息到指定目的地Destination了呢?这是通过Spring为我们封装的消息监听容器MessageListenerContainer实现的,它负责接收信息,并把接收到的信息分发给真正的MessageListener进行处理。每个消费者对应每个目的地都需要有对应的MessageListenerContainer。对于消息监听容器而言,除了要知道监听哪个目的地之外,还需要知道到哪里去监听,也就是说它还需要知道去监听哪个JMS服务器,这是通过在配置MessageConnectionFactory的时候往里面注入一个ConnectionFactory来实现的。所以我们在配置一个MessageListenerContainer的时候有三个属性必须指定,一个是表示从哪里监听的ConnectionFactory;一个是表示监听什么的Destination;一个是接收到消息以后进行消息处理的MessageListener。Spring一共为我们提供了两种类型的MessageListenerContainer,SimpleMessageListenerContainer和DefaultMessageListenerContainer。
  SimpleMessageListenerContainer:SimpleMessageListenerContainer会在一开始的时候就创建一个会话session和消费者Consumer,并且会使用标准的JMS MessageConsumer.setMessageListener()方法注册监听器让JMS提供者调用监听器的回调函数。它不会动态的适应运行时需要和参与外部的事务管理。兼容性方面,它非常接近于独立的JMS规范,但一般不兼容Java EE的JMS限制。

  DefaultMessageListenerContainer:在大多数情况下我们还是使用的DefaultMessageListenerContainer,跟SimpleMessageListenerContainer相比,DefaultMessageListenerContainer会动态的适应运行时需要,并且能够参与外部的事务管理。它很好的平衡了对JMS提供者要求低、先进功能如事务参与和兼容Java EE环境。

消息生产者:

    public static void main(String[] args) {
        ApplicationContext context=new ClassPathXmlApplicationContext("spring-jms.xml");
        JmsTemplate jmsTemplate=(JmsTemplate) context.getBean("jmsTemplate");
        Destination queueDestination=(Destination) context.getBean("queueDestination");
        System.out.println("异步调用执行开始");
        jmsTemplate.send(queueDestination, new MessageCreator(){
            @Override
            public Message createMessage(Session session) throws JMSException {
                return session.createTextMessage("Hello spring JMS");
            }
        });
        System.out.println("异步调用执行结束");
    }

消息监听器:MyMessageListener

public class MyMessageListener implements MessageListener{
    @Override
    public void onMessage(Message message) {
        TextMessage msg= (TextMessage) message;
        try {
            System.out.println("你好:"+msg.getText());
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }
}

启动消息生产者  监听器的执行结果是:

异步调用执行开始
异步调用执行结束
你好:Hello spring JMS

三、发布订阅 同步接收

spring-jms.xml:

<?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:jms="http://www.springframework.org/schema/jms"
xmlns:amq="http://activemq.apache.org/schema/core"
xsi:schemaLocation="http://activemq.apache.org/schema/core
http://activemq.apache.org/schema/core/activemq-core.xsd
http://www.springframework.org/schema/jms
http://www.springframework.org/schema/jms/spring-jms.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">

<!-- ActiveMQConnectionFactory就是JMS中负责创建到ActiveMQ连接的工厂类 -->
<bean id="connectionFactory" class="org.apache.activemq.spring.ActiveMQConnectionFactory" >
     <property name="brokerURL" value="tcp://192.168.0.224:61616"/>  
</bean>
<!-- 创建连接池 -->
<bean id="pooledConnectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory" destroy-method="stop">  
    <property name="connectionFactory" ref="connectionFactory"/>  
    <property name="maxConnections" value="10"/>  
</bean>  
<!-- Spring为我们提供了多个ConnectionFactory,有SingleConnectionFactory和CachingConnectionFactory -->
<bean id="cachingConnectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory">  
    <property name="targetConnectionFactory" ref="pooledConnectionFactory"/>  
</bean> 

<!-- Spring提供的JMS工具类,它可以进行消息发送、接收等 -->  
<bean id="jmsTemplate" 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 -->  
    <property name="connectionFactory" ref="cachingConnectionFactory"/>  
</bean> 

<!--这个是队列目的地,发布订阅-->  
<bean id="topicDestination" class="org.apache.activemq.command.ActiveMQTopic">  
    <constructor-arg index="0" value="spring-Topic"/> 
</bean>   
</beans> 

生产者:

    public static void main(String[] args) {
        ApplicationContext context=new ClassPathXmlApplicationContext("spring-jms.xml");
        JmsTemplate jmsTemplate=(JmsTemplate) context.getBean("jmsTemplate");
        Destination topicDestination=(Destination) context.getBean("topicDestination");
        jmsTemplate.send(topicDestination, new MessageCreator(){
            @Override
            public Message createMessage(Session session) throws JMSException {
                return session.createTextMessage("Hello spring JMS topicDestination");
            }
        });
    }

消费者:

public class SpringJmsSubscriber {
    public static void main(String[] args) {
        ApplicationContext context=new ClassPathXmlApplicationContext("spring-jms.xml");
        JmsTemplate jmsTemplate=(JmsTemplate) context.getBean("jmsTemplate");
        Destination topicDestination=(Destination) context.getBean("topicDestination");
        String msg=(String) jmsTemplate.receiveAndConvert(topicDestination);
        System.out.println(msg);
    }
}
