SpringBoot RabbitMQ 消费端

引入 Maven 依赖

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-amqp</artifactId>
</dependency>

修改 properties 文件

spring.rabbitmq.addresses=192.168.11.71:5672,192.168.11.72:5672,192.168.11.71:5673
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.rabbitmq.virtual-host=/
spring.rabbitmq.connection-timeout=15000

##     表示消费者消费成功消息以后需要手工的进行签收(ack)，默认为auto
spring.rabbitmq.listener.simple.acknowledge-mode=manual
spring.rabbitmq.listener.simple.concurrency=5
spring.rabbitmq.listener.simple.max-concurrency=10
spring.rabbitmq.listener.simple.prefetch=1

接收组件

@Component
public class RabbitReceive {

    /**
     *     组合使用监听
     *     @RabbitListener @QueueBinding @Queue @Exchange
     * @param message
     * @param channel
     * @throws Exception
     */
    @RabbitListener(bindings = @QueueBinding(
                    value = @Queue(value = "queue-1", durable = "true"),
                    exchange = @Exchange(name = "exchange-1",
                    durable = "true",
                    type = "topic",
                    ignoreDeclarationExceptions = "true"),
                    key = "springboot.*"
                )
            )
    @RabbitHandler
    public void onMessage(Message message, Channel channel) throws Exception {
        //    1. 收到消息以后进行业务端消费处理
        System.err.println("-----------------------");
        System.err.println("消费消息:" + message.getPayload());

        //  2. 处理成功之后 获取deliveryTag 并进行手工的ACK操作, 因为我们配置文件里配置的是 手工签收
        //    spring.rabbitmq.listener.simple.acknowledge-mode=manual
        Long deliveryTag = (Long)message.getHeaders().get(AmqpHeaders.DELIVERY_TAG);
        channel.basicAck(deliveryTag, false);
    }



}

使用配置文件设置 exchange 属性

监听绑定的相关数据 建议放在 properties 文件中

# 配置监听 exchange 规则
spring.rabbitmq.listener.order.exchange.name=order-exchange
spring.rabbitmq.listener.order.exchange.durable=true
spring.rabbitmq.listener.order.exchange.type=topic
spring.rabbitmq.listener.order.exchange.key=order.*

使用配置文件的参数

@RabbitListener(bindings = @QueueBinding(
                    value = @Queue(value = "queue-1", durable = "true"),
                    exchange = @Exchange(name = "${spring.rabbitmq.listener.order.exchange.name}",
                    durable = "${spring.rabbitmq.listener.order.exchange.durable}",
                    type = "${spring.rabbitmq.listener.order.exchange.topic}",
                    ignoreDeclarationExceptions = "true"),
                    key = "${spring.rabbitmq.listener.order.exchange.key}"
                )
            )
    @RabbitHandler
