spring集成JMS访问ActiveMQ

首先我们搭建一个spring-mvc项目,项目可以参考:spring-mvc 学习笔记

步骤:

  1. 在pom.xml中加上需要的包
  2. 修改web.xml,增加IOC容器
  3. spring配置文件application.xml增加对应的bean
  4. 生产者Java代码
  5. 消费者Java代码

 

1.在pom.xml加上需要的包

<!-- ActiveMQ支持 -->
<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-core</artifactId>
    <version>5.7.0</version>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-jms</artifactId>
    <version>4.2.0.RELEASE</version>
</dependency>
<!-- spring的IOC容器 -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>4.2.0.RELEASE</version>
</dependency>
<!-- 因为ActiveMQ使用了xbean,所以要引用 -->
<dependency>
    <groupId>org.apache.xbean</groupId>
    <artifactId>xbean-spring</artifactId>
    <version>3.16</version>
</dependency>

 

2.web.xml的根路径下增加对spring容器的监听(注意:是增加,不是覆盖) 

<web-app>
    <!-- ContextLoaderListener 加载IOC容器,Spring框架的底层是listener -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <!-- 指定Spring的配置文件的路径和名称 -->
        <param-value>classpath:application.xml</param-value>
    </context-param>
    <!-- Bootstraps the root web application context before servlet initialization -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
</web-app>

 

3.application.xml文件如下:

<?xml version="1.0" encoding="UTF-8"?>
<!-- 查找最新的schemaLocation 访问 http://www.springframework.org/schema/ -->
<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" 
    xmlns:amq="http://activemq.apache.org/schema/core" 
    xmlns:jms="http://www.springframework.org/schema/jms"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/jms
        http://www.springframework.org/schema/jms/spring-jms-4.0.xsd
        http://activemq.apache.org/schema/core
        http://activemq.apache.org/schema/core/activemq-core-5.8.0.xsd">

    <!-- 需要扫描注解的包 -->
    <context:component-scan base-package="cn.duanjt"></context:component-scan>

    <!-- 连接工厂,设置地址和用户名密码 -->
    <amq:connectionFactory id="connectionFactory" brokerURL="tcp://127.0.0.1:61616" userName="" password=""></amq:connectionFactory>

    <!-- 工厂连接池,池化,提高效率 -->
    <bean id="cachingConnectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory">
        <constructor-arg name="targetConnectionFactory" ref="connectionFactory"></constructor-arg>
        <property name="sessionCacheSize" value="100"></property>
    </bean>

    <!-- 定义生产者 -->
    <bean id="jmstemplate" class="org.springframework.jms.core.JmsTemplate">
        <constructor-arg name="connectionFactory" ref="cachingConnectionFactory"></constructor-arg>
        <!-- 是否为订阅模式 -->
        <property name="pubSubDomain" value="false"></property>
    </bean>

    <!-- 定义消费者,注册监听器 -->
    <jms:listener-container destination-type="queue" container-type="default" connection-factory="cachingConnectionFactory" acknowledge="auto">
        <jms:listener destination="zd-duanjt" ref="queueReceiver1" />
    </jms:listener-container>

</beans>

 

4.生产者的Java代码

package cn.duanjt.controller;

import javax.jms.*;

import org.springframework.beans.factory.annotation.*;
import org.springframework.jms.core.*;
import org.springframework.web.bind.annotation.*;

@RestController
public class ActiveMQController {
    @Autowired
    @Qualifier("jmstemplate")
    private JmsTemplate jmsTemplate;
    
    @RequestMapping("/SendMsg")
    public String SendMsg(String content) {
        System.out.println("接收到数据:" + content);
        // zd-duanjt是ActiveMQ中队列的名称
        jmsTemplate.send("zd-duanjt", new MessageCreator() {
            
            @Override
            public Message createMessage(Session session) throws JMSException {
                Message message= session.createTextMessage(content);
                return message;
            }
        });
        
        return "success";
    }
}

 

 

5.消费者的Java代码

package cn.duanjt.controller;

import javax.jms.*;

import org.springframework.stereotype.Component;

// 注入到spring容器之后的名称是 queueReceiver1
@Component
public class QueueReceiver1 implements MessageListener {

    @Override
    public void onMessage(Message message) {
        TextMessage textMessage = (TextMessage) message;
        try {
            System.out.println("从ActiveMQ获取数据:" + textMessage.getText());
        } catch (JMSException e) {
            e.printStackTrace();
        }
    }

}

 

 

注意:

1.application.xml文件需要引入ActiveMQ对应的xmlns和xsi:schemaLocation.直接从上面那文件搜索关键字“jms”和"activemq"都是需要引入的。

2.笔者这里是将生产者和消费者写到了一个程序里面,在具体实现的时候可以分开实现

3.关于pom.xml引入了xbean。可以参考http://berdy.iteye.com/blog/815309
