org.springframework.cloud.netflix.hystrix.dashboard.HystrixDashboardConfiguration$ProxyStreamServlet.doGet - Spring Cloud Turbine Streams。

Question

我正在努力 Spring Boot v2.2.6.RELEASE + Eureka + Cloud Config + Hystrix + Turbine 例子： 稻草人 https:/app.pluralsight.comcourse-player?clipId=771ae7a6-e2eb-465a-b7ea-99c8a5531a43。.

在这个例子中，我希望将不同服务的指标汇总到一个单一的服务中。Hystrix 使用Turbine Streams的仪表板。

错误。

我已经在这里上传了完整的代码。https:/github.comJavaNeedspring-cloud-hystrix-turbine-aggregate.git。.

Answer 1

@Ash_P 我能够用你放的代码让仪表盘正常运行。http://localhost:8085/turbine.stream?cluster=TOLLRATE-BILLBOARD

问题1：请检查是否 @EnableTurbine 注释存在于 CoHystrixDashboardApplication 如同在资源库分享中，它被评论了。如果在仪表盘上没有这个基本的开关，你的dashoard将无法消费涡轮流。

@EnableTurbine
@EnableHystrixDashboard
@SpringBootApplication
public class CoHystrixDashboardApplication

问题2:检查rabbit-mq是否在后台运行。使用docker来简化这个问题。

docker run -d --hostname local-rabbit --name test-rmq -p 15672:15672 -p 5672:5672 rabbitmq:3.6.9-management

请检查并告诉我问题是否解决了。
