怎么在SpringBoot中整合ActiveMQ

目录结构

引入 maven依赖

 <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.4.RELEASE</version>
    <relativePath/> 
  </parent>
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
  </properties>
  <dependencies>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>

    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-test</artifactId>
      <scope>test</scope>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-activemq</artifactId>
    </dependency>
  </dependencies>
  <build>
    <plugins>
      <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
      </plugin>
    </plugins>
  </build>

引入 application.yml配置

spring:
 activemq:
  broker-url: tcp://127.0.0.1:61616
  user: admin
  password: admin
queue: springboot-queue
server:
 port: 8080

创建QueueConfig

@Configuration
public class QueueConfig {
  @Value("${queue}")
  private String queue;

  @Bean
  public Queue logQueue() {
    return new ActiveMQQueue(queue);
  }

  @Bean
  public JmsTemplate jmsTemplate(ActiveMQConnectionFactory activeMQConnectionFactory, Queue queue) {
    JmsTemplate jmsTemplate = new JmsTemplate();
    jmsTemplate.setDeliveryMode(2);// 进行持久化配置 1表示非持久化，2表示持久化</span>
    jmsTemplate.setConnectionFactory(activeMQConnectionFactory);
    jmsTemplate.setDefaultDestination(queue); // 此处可不设置默认，在发送消息时也可设置队列
    jmsTemplate.setSessionAcknowledgeMode(4);// 客户端签收模式</span>
    return jmsTemplate;
  }

  // 定义一个消息监听器连接工厂，这里定义的是点对点模式的监听器连接工厂
  @Bean(name = "jmsQueueListener")
  public DefaultJmsListenerContainerFactory jmsQueueListenerContainerFactory(
      ActiveMQConnectionFactory activeMQConnectionFactory) {
    DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
    factory.setConnectionFactory(activeMQConnectionFactory);
    // 设置连接数
    factory.setConcurrency("1-10");
    // 重连间隔时间
    factory.setRecoveryInterval(1000L);
    factory.setSessionAcknowledgeMode(4);
    return factory;
  }
}

beta v1.1版本为第一个版本，简单的整合了基础功能，各位站长拿到程序后，不要纠结后台的功能简单，后续将不断更新扩展。在beta v1.1版本使用过程中遇到什么问题，请登录 www.loftto.com 进行反馈！ 安装说明######重要提醒：程序不支持二级目录安装，请使用一级目录或二级目录绑定！#第一步，确定你的服务器支持PHP+mysql。#第二步，确定你的服务器开启了gd库。#第三步，

@SpringBootApplication
@Component
@EnableScheduling
public class Producer {
  
  @Autowired
  private JmsMessagingTemplate jmsMessagingTemplate;
  
  @Autowired
  private Queue queue;
  
  @Scheduled(fixedDelay=3000)
  public void send() {
    String result = System.currentTimeMillis()+"---测试";
    System.out.println("result"+result);
    jmsMessagingTemplate.convertAndSend(queue,result);
  }
  public static void main(String[] args) {
    SpringApplication.run(Producer.class, args);
  }
}

创建消费者的application.yml

spring:
 activemq:
  broker-url: tcp://127.0.0.1:61616
  user: admin
  password: admin
queue: springboot-queue
server:
 port: 8081

创建消费者：

@Component
@SpringBootApplication
public class consumer {

  private int count =0;
  
  @JmsListener(destination = "${queue}")
  public void receive(TextMessage textMessage,Session session) throws JMSException {
    String text = textMessage.getText();
    
    System.out.println("消费:"+text+"第几次获取消息count："+(++count));
    
    System.out.println();
    String jmsMessageID = textMessage.getJMSMessageID();
  }
 
  public static void main(String[] args) {
    SpringApplication.run(consumer.class,args);
  }
}

结果显示：
