Springboot接入RabbitMQ详细教程

本文适用于对 RabbitMQ 有所了解的人，在此不讨论MQ的原理，只讨论如何接入。其实Spring Boot 集成 RabbitMQ 非常简单，本文章使用的是Spring Boot 提供了spring-boot-starter-amqp

接下来将进入正题，六步轻松教你接入RabbitMQ

1.配置pom文件所依赖的主要jar包

<dependency>      <groupId>org.springframework.amqp</groupId>      <artifactId>spring-rabbit</artifactId>      <version>2.0.4.RELEASE</version> </dependency>

2.配置文件（application.properties）

## rabbitmq spring.rabbitmq.host=127.0.0.1 spring.rabbitmq.port=5672 spring.rabbitmq.username=root spring.rabbitmq.password=root spring.rabbitmq.virtual-host=/  # rabbitmq消息确认 spring.rabbitmq.publisher-confirms=true spring.rabbitmq.publisher-returns=true  ## rabbitmq-config rabbitmq.exchange-key = rabbitmq.test.exchange rabbitmq.routing-key = rabbitmq.test.routing.key rabbitmq.queue-name=rabbitmq.queue.name.test

3.交换机和队列绑定配置

@Value("${rabbitmq.queue-name}") String queueName;  @Value("${rabbitmq.exchange-key}") String exchangeKey;  @Value("${rabbitmq.routing-key}") String routingKey;  @Bean(value = "${rabbitmq.queue-name}") public Queue initOrderCancelQueue(){     return new Queue(queueName) ; }  @Bean(value = "${rabbitmq.exchange-key}") public CustomExchange customExchange(){     Map<String,Object> args=new HashMap<>();     return new CustomExchange(exchangeKey,"topic",true,false,args); }  @Bean public Binding binding(@Qualifier(value = "${rabbitmq.queue-name}") Queue queue,                        @Qualifier(value = "${rabbitmq.exchange-key}") CustomExchange exchange){     return BindingBuilder             .bind(queue)             .to(exchange)             .with(routingKey)             .and(exchange.getArguments()); }

4.生产者

@Value("${rabbitmq.exchange-key}") String exchangeKey;  @Autowired private AmqpTemplate amqpTemplate; /**  * 发送MQ  * @param routingKey  * @param obj 参数  */ public void sendNotification(String routingKey, Object obj){     this.amqpTemplate.convertAndSend(exchangeKey,routingKey,obj); }

5消费者

@RabbitHandler @RabbitListener(queues = "${rabbitmq.queue-name}") public void receiveRabbitmqMsg(Message msg, Channel channel, @Header(AmqpHeaders.DELIVERY_TAG) long tag){     String funcName="接收到RabbitmqMsg";     logger.info("{}:{}",funcName,msg);     try {      }catch(Exception e) {      }finally {      } }

6.测试

@Autowired RabbitmqProducer producer;  @Value("${rabbitmq.routing-key}") String routingKey;  public void sendMsg(){     TestModel testModel =new TestModel();     testModel.setName("fxx");     testModel.setAge(18);     testModel.setGender("girl");     try {         producer.sendNotification(routingKey,testModel);     }catch (Exception e){         logger.error("系统异常："+e.toString());     } }

搞定！就这么简单，赶快自己动手试试吧
