Spring boot 创建名为'；rabbitListenerContainerFactory'；

我有一个springbootmicroservice:zuulapi网关服务器，我正在尝试实现一个Zipkin服务器，它侦听rabbitmq，以便在微服务中记录消息

我已将以下依赖项添加到此微服务：

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-sleuth-zipkin</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.amqp</groupId>
        <artifactId>spring-rabbit</artifactId>
    </dependency>

org.springframework.cloud
斯普林·克劳斯·齐普金
org.springframework.amqp
春兔

我已使用以下命令启动Zipkin服务器：

设置兔子的URI=amqp://localhost java-jar-zipkin.jar

然后我尝试启动microservice，但出现以下错误：

因为Spring AMQP中有一个bug，将在2.1.3版中修复

对于临时修复，您可以启用重试属性来创建建议链

spring.rabbitmq.listener.direct.retry.enabled=true
spring.rabbitmq.listener.simple.retry.enabled=true

希望这能解决您的问题。

我也遇到过同样的问题，将Spring Boot版本更改为2.1.0。RELEASE为我解决了这个问题。你也应该试试。Spring Boot版本2.1.1.RELEASE中的RabbitMQ一定有问题。

添加build.gradle

应用插件：“org.springframework.boot”

springBootVersion=2.1.3.0版本 SpringCloudVersion
