Maven+Apache+Spring使用ActiveMQ避坑步骤

1.导入jar包,spring5使用的jms是1.1,需要手动导入jms2.0的jar包

<!-- https://mvnrepository.com/artifact/javax.jms/javax.jms-api -->
<dependency>
    <groupId>javax.jms</groupId>
    <artifactId>javax.jms-api</artifactId>
    <version>2.0.1</version>
</dependency>
<!-- MQ -->
<!-- https://mvnrepository.com/artifact/org.springframework/spring-jms -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-jms</artifactId>
    <version>5.0.6.RELEASE</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.apache.activemq/activemq-core -->
<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-core</artifactId>
    <version>5.7.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.apache.activemq/activemq-all -->
<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-all</artifactId>
    <version>5.15.3</version>
</dependency>
<!-- end MQ -->

2.新建消费者(监听器)

队列的

package com.project.listener;

import java.io.IOException;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;
import javax.servlet.http.HttpSession;

import org.springframework.beans.factory.annotation.Autowired;

import com.fasterxml.jackson.databind.ObjectMapper;
import com.project.vo.ReplyQueueDto;

public class QueueMessageListener implements MessageListener{
    @Autowired  
    private HttpSession session; 
    @Override
    public void onMessage(Message message) {
        System.out.println("session注入成功"+session);
        TextMessage tm = (TextMessage) message;
        try {
            System.out.println("QueueMessageListener监听到了文本消息：\t"
                    + tm.getText());
            ReplyQueueDto rqd = new ObjectMapper().readValue(tm.getText(), ReplyQueueDto.class);
            System.out.println("[查看是否转换成功了]"+rqd);
            //do something ...
        } catch (JMSException | IOException e) {
            e.printStackTrace();
        }

    }

}

Topic的

package com.project.listener;

import java.io.IOException;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;

import org.springframework.beans.factory.annotation.Autowired;

import com.fasterxml.jackson.databind.ObjectMapper;
import com.project.service.ITaskService;
import com.project.vo.TaskTopicDto;

public class TopicMessageListener implements MessageListener{
    @Autowired
    private ITaskService taskService;
    @Override
    public void onMessage(Message message) {
        TextMessage tm = (TextMessage) message;
        try {
            System.out.println("TopicMessageListener监听到了文本消息：\t"
                    + tm.getText());
            TaskTopicDto ttd = new ObjectMapper().readValue(tm.getText(),TaskTopicDto.class);
            taskService.addTaskPending(ttd);
            System.out.println("添加待处理事件成功!");
            //do something ...
        } catch (JMSException | IOException e) {
            e.printStackTrace();
        }

    }

}

3.spring-mq.xml

<?xml version="1.0" encoding="UTF-8"?>

        <!-- 这个connectionFactory对应的是我们定义的Spring提供的那个ConnectionFactory对象 -->
        <constructor-arg ref="connectionFactory" />
        <!-- 非pub/sub模型（发布/订阅），即队列模式 -->
        <property name="pubSubDomain" value="false" />
    </bean>

    <!-- 定义JmsTemplate的Topic类型,本次项目没有使用到 -->
    <bean id="jmsTopicTemplate" class="org.springframework.jms.core.JmsTemplate">

        <property name="pubSubDomain" value="true" />
    </bean>

    <!--Spring JmsTemplate 的消息生产者 end -->

    <!--队列的名字是reply_queue -->
    <bean id="destinationQueue" class="org.apache.activemq.command.ActiveMQQueue">
        <constructor-arg name="name" value="reply_queue" />
    </bean>

    <!--Topic -->
    <bean id="destinationTopic" class="org.apache.activemq.command.ActiveMQTopic">

    <!-- 消息监听容器-测试用 -->  
    <!--

        <property name="destination" ref="destinationTopic" />  
        <property name="messageListener" ref="topicMessageListener" />  
    </bean> 
</beans>

4.配置web.xml的listener

约束
