如何解决RabbitMQ服务器连接错误在Spring云侦探zipkin（Edgware.SR5）

Question

我需要通过RabbitMQ发送跨度到Zipkin。我使用Spring-Cloud-Sleuth Edgware SR5版本和SpringBoot 1.5.3。发布版本。使用较旧的Spring-Cloud侦察版本（Spring-Cloud-stream-binder-Rabbit-v1.1.4）。释放）它工作正常。

当我尝试启动服务时，我得到了“AsyncReporter{RabbitMQSender{addresses=[localhost:5672]，queue=zipkin}”。“无法建立到RabbitMQ服务器的连接”错误。我已经阅读了文档，但无法解决此问题。

渐变配置：

dependencyManagement {
    imports {
        mavenBom "org.springframework.cloud:spring-cloud-dependencies:Edgware.SR5"
    }
}

compile 'org.springframework.cloud:spring-cloud-starter-sleuth'
compile 'org.springframework.cloud:spring-cloud-starter-zipkin'
compile 'org.springframework.boot:spring-boot-starter-amqp'
compile 'org.springframework.amqp:spring-rabbit'

应用yml：

spring:
  sleuth:
    enabled: true
    async:
      enabled: true
  sampler:
    percentage: 1.0 
  zipkin:
    baseUrl: 
    sender:
      type: rabbit

异常堆栈跟踪：

连接被拒绝：连接

这意味着RabbitMQ没有在localhost:5672上运行（如果在应用程序.yml中没有为其提供主机/端口或地址，这是默认设置）。
