RabbitMQ与SpringBoot整合_消费端

 

配置文件

\src\main\resources\application.properties

server.servlet.context-path=/
server.port=8002

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


##    作业：
##    最好不要在代码里写死配置信息，尽量使用这种方式也就是配置文件的方式
##    在代码里使用     ${}    方式进行设置配置: ${spring.rabbitmq.listener.order.exchange.name}
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.*

        //    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);
    }
