Spring整合JMS入門小Demo之發佈訂閱-消息生產者

首先創建一個新的工程，在pom.xml

<properties>
        <spring.version>4.2.4.RELEASE</spring.version>
    </properties>
 
    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jms</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.9</version>
        </dependency>
        <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-client</artifactId>
            <version>5.13.4</version>
        </dependency>
    </dependencies>

在資源文件包中添加applicationContext-jms-producer.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	   xmlns:context="http://www.springframework.org/schema/context"
	   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
		http://www.springframework.org/schema/context   
		http://www.springframework.org/schema/context/spring-context.xsd">
 
	<!--包掃描-->
	<context:component-scan base-package="com.demo"/>
 
    <!-- 真正可以產生Connection的ConnectionFactory，由對應的 JMS服務廠商提供-->
	<bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
	    <property name="brokerURL" value="tcp://192.168.25.140:61616"/>
	</bean>
 
    <!-- Spring用於管理真正的ConnectionFactory的ConnectionFactory -->
	<bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory">
	<!-- 目標ConnectionFactory對應真實的可以產生JMS Connection的ConnectionFactory -->
	    <property name="targetConnectionFactory" ref="targetConnectionFactory"/>
	</bean>
 
    <!-- Spring提供的JMS工具類，它可以進行消息發送、接收等 -->
	<bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
	    <!-- 這個connectionFactory對應的是我們定義的Spring提供的那個ConnectionFactory對象 -->
	    <property name="connectionFactory" ref="connectionFactory"/>
	</bean>
    <!--這個是隊列目的地，點對點的  文本信息-->
	<bean id="queueTextDestination" class="org.apache.activemq.command.ActiveMQQueue">
	    <constructor-arg value="queue_text"/>
	</bean>
 
	<!--這個是訂閱模式  文本信息-->
	<bean id="topicTextDestination" class="org.apache.activemq.command.ActiveMQTopic">
	    <constructor-arg value="topic_text"/>
	</bean>
 
</beans>

編寫TopicProducer類

package com.pinyougou.demo;

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

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

/**
 * @author lyc
 * @Description:
 * @create 2018-08-22
 */
@Component
public class TopicProducer {

    @Autowired
    private JmsTemplate jmsTemplate;

    @Autowired
    private Destination topicTextDestination;

    /**
     * 發送文本消息
     * @param text
     */
    public void sendTextMessage(final String text){
        jmsTemplate.send(topicTextDestination, new MessageCreator() {
            public Message createMessage(Session session) throws JMSException, JMSException {
                return session.createTextMessage(text);
            }
        });
    }


}

編寫測試類

package com.test;

import com.demo.TopicProducer;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

/**
 * @author lyc
 * @Description:
 * @create 2018-08-22
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:applicationContext-jms-producer.xml")
public class TestTopic {
    @Autowired
    private TopicProducer topicProducer;
    @Test
    public void sendTextQueue(){
        topicProducer.sendTextMessage("spring jsm 發佈訂閱");
    }

}

運行測試類，運行成功

再看管理端：成功
