spring jms理论

singleconnectionfactory和CachingConnectionFactory的区别

1、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。(org.springframework.jms.connection.SingleConnectionFactory)

2、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。我们使用CachingConnectionFactory来作为示例。(org.springframework.jms.connection.CachingConnectionFactory)

ProducerService接口

public interface ProducerService {
    void sendMessage(String message);
}

spring-producer的上下文

<?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:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <context:annotation-config/>
    <!--ActiveMq为我们提供的ConnectionFactory-->
    <bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
        <property name="brokerURL" value="tcp://127.0.0.1:61616"/>
    </bean>
    <!--spring jms为我们提供的连接池-->
    <bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory">
        <property name="targetConnectionFactory" ref="targetConnectionFactory"/>
    </bean>

    <!--一个队列的目的地，点对点的-->
    <bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">
        <constructor-arg value="queue"/>
    </bean>

    <!--配置JmsTemplate，用于发送消息-->
    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
        <property name="connectionFactory" ref="connectionFactory"/>
    </bean>

    <bean class="com.imooc.jms.producer.ProducerServiceImpl"/>
</beans>

ProducerServiceImpl实现类

package com.imooc.jms.producer;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;

import javax.annotation.Resource;
import javax.jms.*;

/**
 * Created by IntelliJ IDEA.
 * Author:zhang.peng
 * Date:2018/10/7/007
 * Description:
 */
public class ProducerServiceImpl implements ProducerService {

    @Autowired
    JmsTemplate jmsTemplate;
    @Resource(name = "queueDestination")
    Destination destination;

    public void sendMessage(final String message) {
        //使用JmsTemplate发送消息
        jmsTemplate.send(destination, new MessageCreator() {
            //创建一个消息
            public Message createMessage(Session session) throws JMSException {
                TextMessage textMessage = session.createTextMessage(message);
                return textMessage;
            }
        });
        System.out.println("发送消息：" + message);
    }
}

AppProducer类，用于启动生产者

package com.imooc.jms.producer;

import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * Created by IntelliJ IDEA.
 * Author:zhang.peng
 * Date:2018/10/7/007
 * Description:
 */
public class AppProducer {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("spring-producer.xml");
        ProducerService producerService = context.getBean(ProducerService.class);
        for (int i = 0; i < 100; i++) {
            producerService.sendMessage("test" + i);
        }
        context.close();
    }
}

启动AppProducer发送消息

创建公用配置文件spring-common.xml用于存放spring-consumer.xml和spring-product.xml的公用配置

<?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:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <context:annotation-config/>
    <!--ActiveMq为我们提供的ConnectionFactory-->
    <bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
        <property name="brokerURL" value="tcp://127.0.0.1:61616"/>
    </bean>
    <!--spring jms为我们提供的连接池-->
    <bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory">
        <property name="targetConnectionFactory" ref="targetConnectionFactory"/>
    </bean>

    <!--一个队列的目的地，点对点的-->
    <bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">
        <constructor-arg value="queue"/>
    </bean>
</beans>

spring-consumer.xml配置

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

    <!--导入公共配置-->
    <import resource="spring-common.xml"/>

    <!--配置消息监听器-->
    <bean id="consumerMessageListener" class="com.imooc.jms.consumer.ConsumerMessageListener"/>
    <!--配置消息监听容器-->
    <bean id="jmsContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <property name="connectionFactory" ref="connectionFactory"/>
        <property name="destination" ref="queueDestination"/>
        <property name="messageListener" ref="consumerMessageListener"/>
    </bean>
</beans>

AppConsumer用于启动监听器，接受消息

package com.imooc.jms.consumer;

import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * Created by IntelliJ IDEA.
 * Author:zhang.peng
 * Date:2018/10/7/007
 * Description:
 */
public class AppConsumer {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("spring-consumer.xml");

    }
}

开启两个消费者连接，启动生产者发送消息

主题模式

spring-common.xml配置

<?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:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <context:annotation-config/>
    <!--ActiveMq为我们提供的ConnectionFactory-->
    <bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
        <property name="brokerURL" value="tcp://127.0.0.1:61616"/>
    </bean>
    <!--spring jms为我们提供的连接池-->
    <bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory">
        <property name="targetConnectionFactory" ref="targetConnectionFactory"/>
    </bean>

    <!--一个队列的目的地，点对点的-->
    <bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">
        <constructor-arg value="queue"/>
    </bean>

    <!--一个主题模式目的地，发布订阅的-->
    <bean id="topicDestination" class="org.apache.activemq.command.ActiveMQTopic">
        <constructor-arg value="topic"/>
    </bean>
</beans>

ProducerServiceImpl中修改

//    @Resource(name = "queueDestination")
    @Resource(name = "topicDestination")
    Destination destination;

spring-consumer.xml中修改

<!--<property name="destination" ref="queueDestination"/>-->
        <property name="destination" ref="topicDestination"/>

主题模式下，先启动订阅者，两个消费者完全接受消息。
