Spring Boot整合activeMQ的简单小示例

AvtiveMQ

1. 下载ActiveMQ
   下载链接，可以根据需求进行下载
   
   我使用的是windows版本的 运行简单便于测试

2. 解压之后点击运行。（可以根据操作系统进行选择32位还是64位的）
   

3. 在浏览器里打开ActiveMQ（http://localhost:8161），默认的 用户名,密码都是admin如图所示则表示打开成功
   

4. 添加依赖 pom.xml

	<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-activemq</artifactId>
	</dependency>

5. 在application.yml中添加属性

spring:
	activemq:
    	broker-url: tcp://localhost:61616
    	user: admin
    	password: admin
    	pool:
      		enabled: false

6. 消息的发送接收
   一、点对点（PTP）模式

• 生产者 Producer

package com.imooc.activeMQ;

import org.apache.activemq.command.ActiveMQQueue;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.stereotype.Service;

import javax.jms.Destination;

/**
 * Created by SeuLab on 2018/10/22.
 */
@Service
public class Producer {
    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    public void sendMessage(String destinationName,String message){
        Destination destination = new ActiveMQQueue(destinationName);
        jmsMessagingTemplate.convertAndSend(destination,message);
    }
}

• 消费者 Consumer

package com.imooc.activeMQ;

import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Service;

/**
 * Created by SeuLab on 2018/10/22.
 */
@Service
public class Consumer {

    @JmsListener(destination = "test.queue")
    public void reviceMessage(String message){
        System.out.println("接收到的数据:"+message);
    }
}

• 测试类

package com.imooc.activeMQ;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import static org.junit.Assert.*;

/**
 * Created by SeuLab on 2018/10/22.
 */
@RunWith(SpringRunner.class)
@SpringBootTest
public class ProducerTest {

    @Autowired
    private Producer producer;

    @Test
    public void sendMessage() throws Exception {
        producer.sendMessage("test.queue","test.queue测试的数据");
    }

}

二、发布/订阅（pub/sub）模式

• 发布者

package com.imooc.activeMQ;

import org.apache.activemq.command.ActiveMQTopic;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.stereotype.Service;

import javax.jms.Destination;

/**
 * Created by SeuLab on 2018/10/22.
 */
@Service
public class Publicsher {

    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    public void sendMessage(String destinationName,String message){
        Destination destination =new ActiveMQTopic(destinationName);
        jmsMessagingTemplate.convertAndSend(destination,message);
    }

}

• 消费者

package com.imooc.activeMQ;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.jms.config.JmsListenerContainerFactory;
import org.springframework.jms.config.SimpleJmsListenerContainerFactory;
import org.springframework.stereotype.Service;

import javax.jms.ConnectionFactory;
import java.util.List;

/**
 * Created by SeuLab on 2018/10/22.
 */

@Service
public class Subscriber {

    @Autowired
    private Publicsher publicsher;

    @JmsListener(destination = "test.topic",containerFactory = "myJmsListenerContainerFactory")
    public void subscriber(String message){
        System.out.println("接收到的数据："+message);
    }

    @Bean
    JmsListenerContainerFactory<?> myJmsListenerContainerFactory(ConnectionFactory connectionFactory){
        SimpleJmsListenerContainerFactory simpleJmsListenerContainerFactory = new SimpleJmsListenerContainerFactory();
        simpleJmsListenerContainerFactory.setConnectionFactory(connectionFactory);
        simpleJmsListenerContainerFactory.setPubSubDomain(true);
        return simpleJmsListenerContainerFactory;
    }

}

package com.imooc.activeMQ;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import static org.junit.Assert.*;

/**
 * Created by SeuLab on 2018/10/22.
 */
@RunWith(SpringRunner.class)
@SpringBootTest
public class PublicsherTest {
    @Autowired
    private Publicsher publicsher;
    @Test
    public void sendMessage() throws Exception {
        publicsher.sendMessage("test.topic","test.topic测试数据");
    }

}
