消费者关键代码

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.*

spring.application.name=rabbit-producer
spring.http.encoding.charset=UTF-8
spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
spring.jackson.time-zone=GMT+8
spring.jackson.default-property-inclusion=NON_NULL

RabbitReceive

	 * @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);
	}
