ActiveMQ學習筆記3——與Spring整合

在第一講中，我們說過ActiveMQ可以支持Spring，這裏我們就來講講ActiveMQ如何整合Spring。

1.pom.xml文件配置

        </dependency>
    </dependencies>


</project>

2.ActiveMQ的配置文件

<?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: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 https://www.springframework.org/schema/context/spring-context.xsd">

    <!--  開啓包的自動掃描  -->
    <context:component-scan base-package="com.jzt"/>

    <!--  配置生產者  -->
    <bean id="connectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory" destroy-method="stop">
        <property name="connectionFactory">
            <!--      正真可以生產Connection的ConnectionFactory,由對應的JMS服務商提供      -->
            <bean class="org.apache.activemq.spring.ActiveMQConnectionFactory">
                <property name="brokerURL" value="tcp://192.168.106.131:61616"/>
            </bean>
        </property>
        <property name="maxConnections" value="100"/>
    </bean>

    <!--  這個是隊列目的地,點對點的Queue  -->
    <bean id="destinationQueue" class="org.apache.activemq.command.ActiveMQQueue">
        <!--    通過構造注入Queue名    -->
        <constructor-arg index="0" value="spring-active-queue"/>
    </bean>

    <!--  這個是隊列目的地,  發佈訂閱的主題Topic-->
    <bean id="destinationTopic" class="org.apache.activemq.command.ActiveMQTopic">
        <constructor-arg index="0" value="spring-active-topic"/>
    </bean>

    <!--  Spring提供的JMS工具類,他可以進行消息發送,接收等  -->
    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
        <!--    傳入連接工廠    -->
        <property name="connectionFactory" ref="connectionFactory"/>
        <!--    傳入目的地    -->
        <property name="defaultDestination" ref="destinationQueue"/>
        <!--    消息自動轉換器    -->
        <property name="messageConverter">
            <bean class="org.springframework.jms.support.converter.SimpleMessageConverter"/>
        </property>
    </bean>
</beans>

3.隊列模式

生產者：

package com.jzt;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import org.springframework.stereotype.Service;

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

/**
 * @author sj
 */
@Service
public class QueueProducer {
    @Autowired
    private JmsTemplate jmsTemplate;

    public static void main(String[] args) {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("activemq.xml");
        System.out.println(applicationContext);
        QueueProducer queueProducer = applicationContext.getBean(QueueProducer.class);
        queueProducer.jmsTemplate.send(new MessageCreator() {
            public Message createMessage(Session session) throws JMSException {
                return session.createTextMessage("***Spring整合ActiveMQ的消息.....");
            }
        });
        System.out.println("********send task over");
    }
}

啓動，查看MQ控制檯：

可以看到消息發送成功。

 

消費者：

1）使用receive()方法接收：

package com.jzt;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Service;

/**
 * @author sj
 */
@Service
public class QueueConsumer {

    @Autowired
    private JmsTemplate jmsTemplate;

    public static void main(String[] args) {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("activemq.xml");
        QueueConsumer queueConsumer = applicationContext.getBean(QueueConsumer.class);
        String message = (String) queueConsumer.jmsTemplate.receiveAndConvert();
        System.out.println(message);
    }
}

啓動消費者，

發現消息已經被消費完成。

2）使用監聽器接收消息：

首先需要添加監聽器配置

<!-- 配置監聽器 -->
    <bean id="messageListener" class="com.jzt.QueueListener"></bean>

    <!--配置監聽器 -->
    <bean id="jmsContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <!--    傳入連接工廠    -->
        <property name="connectionFactory" ref="connectionFactory"/>
        <!--    傳入目的地    -->
        <property name="destination" ref="destinationQueue"/>

        <property name="messageListener" ref="messageListener"/>
    </bean>

消費者：

package com.jzt;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Service;

/**
 * @author sj
 */
@Service
public class QueueConsumer2 {

    public static void main(String[] args) {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("activemq.xml");
        QueueConsumer2 queueConsumer2 = applicationContext.getBean(QueueConsumer2.class);
    }
}

啓動後發現可以正常消費消息，說明監聽器配置成功了。

發佈訂閱模式代碼類似，就不在重複。

 

小結：

    通過整合Spring，能夠更靈活的支持ActiveMQ的功能，同時也支持各種自定義的功能，滿足我們實際項目開發中的場景。
