快速开发简单rabbit四部曲

一、配置类以及配置文件

　　配置类主要作用是声明消息队列的名称

@Configuration
public class TestMqConfig {

    public static final String TEST_DIRECT_QUEUE = "test-queue";

    /**
     * 创建直连式队列
     *
     * @return org.springframework.amqp.core.Queue
     */
    @Bean
    public Queue yadoQueue() {
        return new Queue(TEST_DIRECT_QUEUE, true);
    }

}

  

   

 

 

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    type: com.alibaba.druid.pool.DruidDataSource
    username: root
    password: root
    url: jdbc:mysql://127.0.0.1:3306/test?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=GMT%2B8&allowMultiQueries=true&allowPublicKeyRetrieval=true
    druid:
      #初始化大小，最小，最大，超时链接，空闲时间，生产时间，pscache
      initialSize: 5
      minIdle: 5
      maxActive: 20
      maxWait: 60000
      timeBetweenEvictionRunsMillis: 60000
      minEvictableIdleTimeMillis: 300000
      validationQuery: SELECT 1 FROM DUAL
      testWhileIdle: true
      testOnBorrow: false
      testOnReturn: false
      poolPreparedStatements: true
      maxPoolPreparedStatementPerConnectionSize: 20
  rabbitmq:
    host: 127.0.0.1
    port: 5672
    username: guest
    password: guest

二、开发消息生产者

@Service
public class TestProducer {

    @Resource
    private RabbitTemplate rabbitTemplate;

    public void sendMessage(String message) {
        rabbitTemplate.convertAndSend(TestMqConfig.TEST_DIRECT_QUEUE, message);
    }

}

 三、开发消息消费者

@Component
@Slf4j
public class TestConsumer {

    @RabbitListener(queues = TestMqConfig.TEST_DIRECT_QUEUE)
    @RabbitHandler
    public void getMessage(Object object) {
        log.info("消息：消费者={}", object);
    }

}

 四、使用定时任务调度生产者进行测试

@Component
@Slf4j
public class TestScheduled {

    @Resource
    TestProducer testProducer;

    @Scheduled(cron = "0/10 * * * * ? ")
    public void testSend() {
        String msg = System.currentTimeMillis() + "msg";
        testProducer.sendMessage(msg);
    }

}

 

 

 

 

 

 

 

 

启动应用程序即可在控制台看到消费者消费消息
