异常摘要：org.springframework.amqp.AmqpConnectException：java.net.ConnectException：连接被拒绝

Question

使用gradle构建spring cloud总线客户端，build.gradle如下：

server.crt

当我使用spring-cloud-bus时，我遇到了问题：

apply plugin: "spring-boot"

    ext {
      springCloudConfigVersion = "1.0.2.RELEASE"
      springCloudStarterVersion = "1.0.2.RELEASE"
    }

    dependencyManagement {
      imports {
        mavenBom "org.springframework.cloud:spring-cloud-config:${springCloudConfigVersion}"
        mavenBom "org.springframework.cloud:spring-cloud-starter-parent:${springCloudStarterVersion}"
      }
    }

    dependencies {
      compile(project(":video-service:video-service-api"))
      compile("org.springframework.boot:spring-boot-starter-data-mongodb")
      compile("org.springframework.boot:spring-boot-starter-web")
      compile("org.springframework.boot:spring-boot-starter-actuator")
      compile("org.springframework.cloud:spring-cloud-starter")
      compile("org.springframework.cloud:spring-cloud-starter-eureka")
      compile("org.springframework.cloud:spring-cloud-starter-bus-amqp")
      testCompile("org.springframework.boot:spring-boot-starter-test")
    }

config server application.yml：

o.s.a.r.l.SimpleMessageListenerContainer : Consumer raised exception, processing can restart if the connection factory supports it. Exception summary: org.springframework.amqp.AmqpConnectException: java.net.ConnectException: Connection refused
