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 项目对消息各种支持。
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
