1 注解的字段 @RabbitListener注解指定目标方法作为消费消息的方法,通过注解参数指定所监听的队列或者Binding。...1.1 containerFactory 使用@RabbitListener的containerFactory可设置一个自己明确默认值的RabbitListenerContainerFactory对象。...可以在配置文件中设置RabbitListenerAnnotationBeanPostProcessor并通过设置@RabbitListener的执行 也可以通过@EnableRabbit注解来启用@RabbitListener...factory.setConnectionFactory(connectionFactory); return factory; } } 定义消息处理器,@RabbitListener...注解标记的方法 @Component public class MessageHandler { @RabbitListener(queues = "zhihao.miao.order")
1、我们在主配置类中加上@EnableRabbit开启基于注解的RabbitMq 2、我们建立一个BookService.java并为相关方法加上@RabbitListener注解,启动服务器: package...com.gong.springbootrabbitmq.service; import com.gong.springbootrabbitmq.bean.Book; import org.springframework.amqp.rabbit.annotation.RabbitListener...; import org.springframework.stereotype.Service; @Service public class BookService { @RabbitListener...3、第二种收消息的模式 @RabbitListener(queues = "gong") public void recieve2(Message message){ System.out.println

之前介绍了 rabbitmq 的消息发送姿势,既然有发送,当然就得有消费者,在 SpringBoot 环境下,消费可以说比较简单了,借助@RabbitListener注解,基本上可以满足你 90%以上的业务开发需求...下面我们来看一下@RabbitListener的最最常用使用姿势 I....消费姿势 本文将目标放在实用性上,将结合具体的场景来演示@RabbitListener的使用姿势,因此当你发现看完本文之后这个注解里面有些属性还是不懂,请不要着急,下一篇会一一道来 0. mock 数据...通常这种场景下,是需要我们来主动创建 Queue,并建立与 Exchange 的绑定关系,下面给出@RabbitListener的推荐使用姿势 /** * 队列不存在时,需要创建一个队列,并且与exchange...绑定 */ @RabbitListener(bindings = @QueueBinding( value = @Queue(value = "topic.n1", durable =
监听rabbitmq 监听rabbitmq使用的是@RabbitListener注解 @RabbitListener 用法使用 @RabbitListener注解标记方法,当监听到队列 debug 中有消息时则会进行接收并处理...监听atguigu.news和atguigu队列,导入@RabbitListener注释器是.amqp.rabbit下的 import org.springframework.amqp.core.Message...; import org.springframework.amqp.rabbit.annotation.RabbitListener; import org.springframework.stereotype.Service...; /** * @author: 毛利 */ @Service public class BookService { @RabbitListener(queues = "atguigu.news...总结 本文通过@RabbitListener用监听rabbitmq的队列和使用amqpAdmin创建交换器,队列。 希望以上对你学习有用 再自我介绍一下吧。我叫润森,是一个的学习者。
