更新時(shí)間：2026年05月06日 09:14:07 作者：星空_燈塔

本文總結(jié)了在使用RabbitMQ和Spring Cloud Stream時(shí)遇到的4個(gè)常見(jiàn)問(wèn)題,并給出了相應(yīng)的解決方案,包括生產(chǎn)者路由綁定、隊(duì)列組名稱、輸入輸出通道定義不正確等問(wèn)題

問(wèn)題一

一個(gè)交換機(jī)，多個(gè)隊(duì)列，每個(gè)隊(duì)列路由不同，向其中一個(gè)隊(duì)列發(fā)送消息后，所有隊(duì)列都能接收到消息

原因

沒(méi)有綁定確定的路由

解決

添加生產(chǎn)者路由綁定

#配置方式一：A工程作為生產(chǎn)者生產(chǎn)消息，B工程作為消費(fèi)者訂閱消息
#生產(chǎn)者：A工程
spring:
  cloud:
    stream:
      default-binder: rabbit
      bindings:
        A_stream:
          binder: rabbit
          destination: A-exchange-dev-4
          group: group_A
      rabbit:
        bindings:
          A_stream:
            consumer:
              exchangeType: topic
              autoBindDlq: true
              republishToDlq: true
              bindingRoutingKey: group_A
            producer:
              bindingRoutingKey: group_A
              routingKeyExpression: '''group_A'''
#消費(fèi)者：B工程
spring:
  cloud:
    stream:
      default-binder: rabbit
      bindings:
        A_stream:
          binder: rabbit
          destination: A-exchange-dev-4
          group: group_A
      rabbit:
        bindings:
          A_stream:
            consumer:
              exchangeType: topic
              autoBindDlq: true
              republishToDlq: true
              bindingRoutingKey: group_A
            producer:
              bindingRoutingKey: group_A
              routingKeyExpression: '''group_A'''

問(wèn)題二

兩個(gè)不同交換機(jī)對(duì)應(yīng)不同隊(duì)列，隊(duì)列組名稱相同，生產(chǎn)者消費(fèi)者綁定路由key相同，發(fā)送消息，目的交換機(jī)路由未收到消息，另一個(gè)卻收到消息

原因

隊(duì)列組相同

解決

修改隊(duì)列組，使交換機(jī)路由組生產(chǎn)者消費(fèi)者路由key不同，否則，不能使消息發(fā)送到目的路由

問(wèn)題三

一個(gè)隊(duì)列既是消費(fèi)者又是生產(chǎn)者，如果生產(chǎn)者和消費(fèi)者使用同一配置，容易出現(xiàn)查不到消費(fèi)者的情況

解決

生產(chǎn)者和消費(fèi)者使用不同通道

#配置方式二：同一工程中既是消費(fèi)者又是生產(chǎn)者，生產(chǎn)者消費(fèi)者分開(kāi)配置
spring:
  cloud:
    stream:
      default-binder: rabbit
      bindings:
        A_output_stream:
          binder: rabbit
          destination: A-exchange-dev-4
          group: group_A
        A_input_stream:
          binder: rabbit
          destination: A-exchange-dev-4
          group: group_A
      rabbit:
        bindings:
          A_output_stream:
            producer:
              bindingRoutingKey: group_A
              routingKeyExpression: '''group_A'''
          A_input_stream:
            consumer:
              exchangeType: topic
              autoBindDlq: true
              republishToDlq: true
              bindingRoutingKey: group_A

問(wèn)題四

啟動(dòng)報(bào)錯(cuò)

如下：

Caused by: com.rabbitmq.client.ShutdownSignalException: channel error; protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - inequivalent arg 'x-dead-letter-exchange' for queue 'exchange-dev-4-test001.product_sync' in vhost '/': received none but current is the value 'DLX' of type 'longstr', class-id=50, method-id=10)

......

org.springframework.cloud.stream.binder.BinderException: Exception thrown while starting consumer: ......

Caused by: org.springframework.beans.factory.support.BeanDefinitionOverrideException: Invalid bean definition with name 'exchange-dev-4-test001.product_sync.errors.recoverer' defined in null: Cannot register bean definition [Root bean: class [org.springframework.integration.handler.advice.ErrorMessageSendingRecoverer]; scope=; abstract=false; lazyInit=null; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null] for bean 'exchange-dev-4-test001.product_sync.errors.recoverer': There is already [Root bean: class [org.springframework.integration.handler.advice.ErrorMessageSendingRecoverer]; scope=; abstract=false; lazyInit=null; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null] bound.

原因

bean 定義無(wú)效，已經(jīng)有 bean 綁定。本次報(bào)錯(cuò)的原因是 bean 中對(duì)輸入通道[@Input(ProductSyncQueueComponent .INPUT)]重復(fù)定義

在同一個(gè)工程中，[exchange-dev-4-test001.product_sync]既是消費(fèi)者又是生產(chǎn)者，啟動(dòng)程序時(shí)報(bào)錯(cuò)，在 mq 隊(duì)列查看 routingKey 時(shí)發(fā)現(xiàn)有兩個(gè)，一個(gè)是自定義的[product_sync]，一個(gè)是默認(rèn)的[#]，導(dǎo)致了生產(chǎn)者發(fā)送的消息消費(fèi)者接收不到。

根據(jù)報(bào)錯(cuò)提示 bean 定義無(wú)效，檢查自定義stream bean 時(shí)發(fā)現(xiàn)下列代碼中生產(chǎn)者和消費(fèi)者都定義成了輸入通道，輸入輸出通道定義不正確。

@Component
public interface ProductSyncQueueComponent {
    /**
     * Input channel name.
     */
    String INPUT = "product_sync_input_stream";

    @Input(ProductSyncQueueComponent.INPUT)
    SubscribableChannel input();

    /**
     * Output channel name.
     */
    String OUTPUT = "product_sync_output_stream";

    @Output(ProductSyncQueueComponent.OUTPUT)
    SubscribableChannel output();
}
