问题
I need to send spans through RabbitMQ to Zipkin. I'm Using Spring-Cloud-Sleuth Edgware-SR5 version and SpringBoot 1.5.3.RELEASE versions. With older Spring-cloud sleuth version (spring-cloud-stream-binder-rabbit - v1.1.4.RELEASE) it was working fine.
When I try to start the service, I'm getting " "AsyncReporter{RabbitMQSender{addresses=[localhost:5672], queue=zipkin}}. Unable to establish connection to RabbitMQ server" error. I have gone through the documentations, but I could't able to resolve this issue.
Gradle Configuration:
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'
Application.yml:
spring:
sleuth:
enabled: true
async:
enabled: true
sampler:
percentage: 1.0
zipkin:
baseUrl:
sender:
type: rabbit
Exception StackTrace:

Thanks and Regards Suresh
回答1:
Connection refused: connect
Simply means that RabbitMQ is not running on localhost:5672
(which is the default if you don't provide a host/port, or addresses, for it in your application.yml
).
