Spring Cloud 2.x系列之springboot集成ActiveMQ

更新时间:2022-09-18 19:12:26

消息队列中间件是分布式系统中重要的组件,主要解决应用耦合,异步消息,流量削锋等问题。实现高性能,高可用,可伸缩和最终一致性架构;是大型分布式系统不可缺少的中间件。目前使用较多的消息队列有ActiveMQ、RabbitMQ、Kafka、RocketMQ、MetaMQ等。springboot提供了对JMS系统的支持;springboot很方便就可以集成这些消息中间件。

对于异步消息在实际的应用之中会有两类:

JMS:代表作就是 ActiveMQ,但是其性能不高,因为其是用 java 程序实现的。

AMQP:直接利用协议实现的消息组件,其大众代表作为RabbitMQ,高性能代表作为Kafka。

1、新建项目,对应的pom.xml文件如下

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0http://maven.apache.org/xsd/maven-4.0.0.xsd">

   <modelVersion>4.0.0</modelVersion>


   <groupId>spring-cloud</groupId>

   <artifactId>sc-activeMQ</artifactId>

   <version>0.0.1-SNAPSHOT</version>

   <packaging>jar</packaging>


   <name>sc-activeMQ</name>

   <url>http://maven.apache.org</url>



   <parent>

      <groupId>org.springframework.boot</groupId>

      <artifactId>spring-boot-starter-parent</artifactId>

      <version>2.0.4.RELEASE</version>

   </parent>



   <dependencyManagement>

      <dependencies>

        <dependency>

           <groupId>org.springframework.cloud</groupId>

           <artifactId>spring-cloud-dependencies</artifactId>

           <version>Finchley.RELEASE</version>

           <type>pom</type>

           <scope>import</scope>

        </dependency>



      </dependencies>

   </dependencyManagement>



   <properties>

      <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

      <maven.compiler.source>1.8</maven.compiler.source>

      <maven.compiler.target>1.8</maven.compiler.target>

   </properties>


   <dependencies>

      <dependency>

        <groupId>org.springframework.boot</groupId>

        <artifactId>spring-boot-starter-activemq</artifactId>

      </dependency>

      <dependency>

        <groupId>org.apache.activemq</groupId>

        <artifactId>activemq-core</artifactId>

        <version>5.7.0</version>

      </dependency>


      <dependency>

        <groupId>org.apache.activemq</groupId>

        <artifactId>activemq-pool</artifactId>

      </dependency>



      <dependency>

        <groupId>org.springframework.boot</groupId>

        <artifactId>spring-boot-starter-web</artifactId>

      </dependency>

      <dependency>

        <groupId>org.springframework.boot</groupId>

        <artifactId>spring-boot-starter-test</artifactId>

        <scope>test</scope>

      </dependency>

   </dependencies>

</project>

2、新建springboot启动类ActiveMqApplication.java

package sc.activemq;


import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;



@SpringBootApplication

publi cclass ActiveMqApplication {


   public static void main(String[] args){

      SpringApplication.run(ActiveMqApplication.class, args);

   }



}

3、新建配置文件application.yml

server:

  port: 9080

spring:

  appliction:

   name: sc-activemq

  activemq:

    broker-url:tcp://localhost:61616

    in-memory: true 

    user: admin

    password: admin

    pool:

      enabled: true

      max-connections: 50

      expiry-timeout:10000

      idle-timeout: 30000

  jms:

    pub-sub-domain: false #默认情况下activemq提供的是queue模式,若要使用topic模式需要配置pub-sub-domain为true

说明:默认情况下activemq提供的是queue模式,若要使用topic模式需要配置spring.jms.pub-sub-domain为true

4、新建消费生产者

package sc.activemq.service.impl;

import javax.jms.Destination;

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

import org.springframework.jms.core.JmsMessagingTemplate;

import org.springframework.stereotype.Service;

import sc.activemq.service.ProductService;

@Service
publicclass ProductServiceImpl implements ProductService {

    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    @Override

    public void sendMessage(Destinationdestination, String message) {

       jmsMessagingTemplate.convertAndSend(destination,message);

    }
}

5、新建消息消费者

队列模式:

package sc.activemq.service.consumer;

import org.springframework.jms.annotation.JmsListener;

import org.springframework.stereotype.Component;


@Component

publicclass ConsumerQueue{


   // 使用JmsListener配置消费者监听的队列,其中text是接收到的消息

   @JmsListener(destination = "jms-queue")

   public void receiveQueue(String text) {

      System.out.println("ConsumerQueue收到:" + text);

   }

}

订阅模式:

package sc.activemq.service.consumer;


import org.springframework.jms.annotation.JmsListener;

import org.springframework.stereotype.Component;



@Component

publicclass ConsumerTopic{


   // 使用JmsListener配置消费者监听的队列,其中text是接收到的消息

   @JmsListener(destination = "jms-topic")

   public void receiveQueue(String text) {

      System.out.println("ConsumerTopic收到:" + text);

   }

}

6、新建测试类

package sc.activemq;


import org.apache.activemq.command.ActiveMQQueue;

import org.apache.activemq.command.ActiveMQTopic;

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 sc.activemq.service.ProductService;



@RunWith(SpringRunner.class)

@SpringBootTest

publicclass ActiveMqTest {



   @Autowired

   private ActiveMQQueue queue;



   @Autowired

   private ActiveMQTopic topic;



   @Autowired

   private ProductService productService;



   @Test

   public void testJms() {

      String msgQueue = "send 黄金 ";

      for(inti=0; i<5; i++){

        productService.sendMessage(this.queue, msgQueue+i);

      }

      String msgTopic = "send 白银 ";

      for(inti=0; i<5; i++){

        productService.sendMessage(this.topic, msgTopic+i);

      }

      try {

        Thread.sleep(10000);

      } catch(InterruptedException e) {

      }

   }

}

7、进行测试

先登录ActiveMq管理平台:http://localhost:8161/

  队列模式:

(1)配置spring.jms.pub-sub-domain为false
