我有一个 Turbine 和 Hystrix 设置在工作，但决定将其更改为 Turbine AMQP，这样我就可以将多个服务聚合到一个流/仪表板中。
我已经设置了一个在 localhost:8989 上运行的 Turbine AMQP 服务器，但它似乎没有从客户端服务获取 Hystrix 数据。当我在浏览器中访问 Turbine 服务器的 IP 时，我反复看到 data: {"type":"Ping"}，即使我正在轮询 Hystrix 的 URL。如果我尝试在 Hystrix 仪表板中显示 Turbine AMQP 流，我会得到:Unable to connect to Command Metric Stream。
我在端口 5672 上默认安装了 RabbitMQ。
我使用 Hystrix-AMQP 的客户端服务有一个 application.yml 文件，如下所示:
spring:
application:
name: policy-service
eureka:
client:
serviceUrl:
defaultZone: http://localhost:8761/eureka/
spring:
rabbitmq:
addresses: ${vcap.services.${PREFIX:}rabbitmq.credentials.uri:amqp://${RABBITMQ_HOST:localhost}:${RABBITMQ_PORT:5672}}

为什么 Turbine AMQP 服务器没有从 Hystrix AMQP 客户端接收通信有什么想法吗？
编辑:Turbine-AMQP 主体看起来像:
package com.turbine.amqp;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.turbine.amqp.EnableTurbineAmqp;
import org.springframework.context.annotation.Configuration;
@Configuration
@EnableAutoConfiguration
@EnableTurbineAmqp
@EnableDiscoveryClient
public class TurbineAmqpApplication {
public static void main(String[] args) {
SpringApplication.run(TurbineAmqpApplication.class, args);
}
}
这是它的 application.yml:
server:
port: 8989
spring:
rabbitmq:
addresses: ${vcap.services.${PREFIX:}rabbitmq.credentials.uri:amqp://${RABBITMQ_HOST:localhost}:${RABBITMQ_PORT:5672}}
点击http://localhost:8989/turbine.stream 会产生一个重复的数据流:{"type":"Ping"}
并在控制台中显示:

我对 turbine-amqp 的依赖如下:
dependencies {
compile('org.springframework.cloud:spring-cloud-starter-turbine-amqp:1.0.3.RELEASE')
compile 'org.springframework.boot:spring-boot-starter-web:1.2.5.RELEASE'
compile 'org.springframework.boot:spring-boot-starter-actuator:1.2.5.RELEASE'
testCompile("org.springframework.boot:spring-boot-starter-test")
}
dependencyManagement {
imports {
mavenBom 'org.springframework.cloud:spring-cloud-starter-parent:1.0.2.RELEASE'
}
}
最佳答案
很难找到解决方案。
使用 Spring cloud 2.1.4.RELEASE 我遇到了类似的问题。
主要原因是 rabbitMQ 之间的不兼容[交换]名称: spring-cloud-netflix-hystrix-stream 和 spring-cloud-starter-netflix-turbine-stream。
于是解决: 启动服务组件时查看创建的名称 exchange name {与声明 hystrix-stream 的相同}
在声明 {turbine-stream} 的组件上 更新属性
turbine.stream.destination=
以我为例 turbine.stream.destination=hystrixStreamOutput
关于rabbitmq - Turbine AMQP 不接收 Hystrix 流，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/32573966/
