Turbine AMQP 不接收 Hystrix 流
Posted
技术标签:
【中文标题】Turbine AMQP 不接收 Hystrix 流【英文标题】：Turbine AMQP does not receive Hystrix stream 【发布时间】：2015-12-10 23:53:54 【问题描述】：我有一个 Turbine 和 Hystrix 设置工作，但决定将其更改为 Turbine AMQP，以便我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。当我在浏览器中点击 Turbine 服务器的 IP 时，我会反复看到 data: "type":"Ping"，即使我正在轮询 Hystrix 的 URL。如果我尝试在 Hystrix Dashboard 中显示 Turbine AMQP 流，我会得到：Unable to connect to Command Metric Stream.
我在端口 5672 上运行了默认安装的 RabbitMQ。
我使用 Hystrix-AMQP 的客户端服务有一个如下所示的 application.yml 文件：
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
启动日志的尾部是这样的：

任何想法为什么 Turbine AMQP 服务器没有接收到来自 Hystrix AMQP 客户端的通信？
编辑：Turbine-AMQP 主要看起来像：
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data: "type":"Ping" 的重复流
并在控制台中显示：
2015-09-15 08:54:37.960 INFO 83480 --- [o-eventloop-3-1] o.s.c.n.t.amqp.TurbineAmqpConfiguration : SSE Request Received

我对turtle-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'

mavenBom 'org.springframework.cloud:spring-cloud-starter-parent:1.0.2.RELEASE'
【问题讨论】：
没有。你锻炼过断路器吗？ Turbo-amqp 应用程序的配置和主要功能是什么样的？你可以点击http://localhost:8989/turbine.stream 上出现 ping
我可以看到消息正在 Rabbit MQ 管理控制台中传递。
【参考方案1】：
很难找到解决办法。
使用 Spring cloud 2.1.4.RELEASE 我遇到了类似的问题。
主要原因是rabbitMQ中的[exchanges]名称不兼容： spring-cloud-netflix-hystrix-stream 和 spring-cloud-starter-netflix-turbine-stream。
所以解决它： 启动服务组件时查看名称创建的交换名称与声明 hystrix-stream 相同
在声明 turbine-stream 的组件上 更新属性
turbine.stream.destination=
就我而言 Turbo.stream.destination=hystrixStreamOutput
【讨论】：
你能举个完整的例子吗？ @Marcelus - 'turbine.stream.destination' 是一个未知属性。您在 pom.xml 中添加了哪些额外的依赖项？ @Marcelus - 请您在这里指导我：***.com/questions/59738969/… ？ 谢谢，我一直在为spring.cloud.version 的事情苦苦挣扎【参考方案2】：
我遇到了类似的问题，我找到了解决方案。
我的 Spring Cloud 版本是 2.1.0.RELEASE
解决办法：
-
添加属性
spring.cloud.stream.bindings.turbineStreamInput.destination: hystrixStreamOutput
turbine.stream.enabled: false
-
添加自动配置
@EnableBinding(TurbineStreamClient.class)
public class TurbineStreamAutoConfiguration
@Autowired
private BindingServiceProperties bindings;
@Autowired
private TurbineStreamProperties properties;
@PostConstruct
public void init()
BindingProperties inputBinding = this.bindings.getBindings()
.get(TurbineStreamClient.INPUT);
if (inputBinding == null)
this.bindings.getBindings().put(TurbineStreamClient.INPUT,
new BindingProperties());
BindingProperties input = this.bindings.getBindings()
.get(TurbineStreamClient.INPUT);
if (input.getDestination() == null)
input.setDestination(this.properties.getDestination());
if (input.getContentType() == null)
input.setContentType(this.properties.getContentType());
@Bean
public HystrixStreamAggregator hystrixStreamAggregator(ObjectMapper mapper,
PublishSubject<Map<String, Object>> publisher)
return new HystrixStreamAggregator(mapper, publisher);
