spring boot 2.0+ 整合RabbitMq

1、添加包

1 <dependency>
2       <groupId>org.springframework.boot</groupId>
3      <artifactId>spring-boot-starter-amqp</artifactId>
4 </dependency>

2、配置文件

pring:
  # 消息队列
  rabbitmq:
    username: admin
    password: admin
    port: 5672
    host: 192.168.1.118
    listener:
      simple:
        acknowledge-mode: manual

3、生产者，其中MSGRABBITQUERENAME为队列名称

 1 @Component
 2 public class RabbitProducer {
 3 
 4     @Autowired
 5     AmqpTemplate rabbitTemplate;
 6 
 7     static final String MSGRABBITQUERENAME="chat.send.msg";
 8 
 9     public void sendMessages(String str) {
10         this.rabbitTemplate.convertAndSend(MSGRABBITQUERENAME,str);
11     }
12 }

4、消费者，我这里为手动确认模式，确保数据有效性。

@Component
public class RabbitListener {

    @org.springframework.amqp.rabbit.annotation.RabbitListener(queues = "leenleda.test")
    public void onMessage(@Payload String msg,
                          @Headers Map<String, Object> headers,
                          Channel channel) throws Exception{
        try {
            //消息确认,(deliveryTag,multiple是否确认所有消息)
            channel.basicAck((Long) headers.get(AmqpHeaders.DELIVERY_TAG), false);
        } catch (Exception e) {
            //消息拒绝(deliveryTag,multiple,requeue拒绝后是否重新回到队列)
            channel.basicNack((Long) headers.get(AmqpHeaders.DELIVERY_TAG), false, true);
            // 拒绝一条
            // channel.basicReject();
        }
    }
}

 

然后直接调用就可以了
