Hystrix仪表板始终显示加载屏幕

如何解决Hystrix仪表板始终显示加载屏幕

我已经使用Netflix-OSS库开发了微服务应用程序。我在本地主机：9091 / hystrix上运行的Hystrix仪表板上遇到问题。我想监视微服务A和微服务B之间的请求指标。端点“ hystrix.stream”已经注册。

hystrix仪表板在加载时卡住，但未显示任何结果。

我检查了浏览器，发现jquery错误- 未被捕获的TypeError：e.indexOf不是似乎是jquery版本问题的函数。

我正在使用Jdk 14版本和Spring Boot 2.3进行开发

解决方法

            @bob0the0mighty
            I am adding code snippet for your reference. This is my springboot main class
            @SpringBootApplication
            @EnableEurekaClient
            @EnableCircuitBreaker
            @EnableHystrixDashboard
            public class DramaServiceApplication {
            }
        My controller looks like :
        @GetMapping("/acts")
            @com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand(fallbackMethod = "fallbackMethodForGetActor",commandKey = "test-Act",groupKey = "test-Act")
            public ActorList getActors() {
                ActorList actorList = restTemplate.getForObject("http://actor-service/actor/actorsList",ActorList.class);
                return actorList;
            }
    public ActorList fallbackMethodForGetActor() {
            return new ActorList(" Requested Actor page is under maintenance!!");
        }
    
    application.yml file looks like :
            
    management:
      endpoints:
        web:
          base-path: /
          exposure:
            include: hystrix.stream,health,info,metrics
After hitting request multiple times,I am getting hystrix dashboard as "loading" always
and screen looks like

将spring-cloud-dependencies版本更新为“ Hoxton.SR7”对我来说解决了这个问题。 带有弹簧云依赖版本“ Hoxton.SR6”的jquery 3.4.1出现问题。

您可以在此处获取问题的详细信息和解决方案。 https://github.com/spring-cloud/spring-cloud-netflix/issues/3811 https://github.com/spring-cloud/spring-cloud-netflix/pull/3817

,

This issue got fixed by adding following configuration changes:
1. Updating Hoxton to SR7 in pom.xml:
   <properties>
        <java.version>14</java.version>
        <spring-cloud.version>Hoxton.SR7</spring-cloud.version>
    </properties>
2. Add these entries in application.yml:
hystrix:
  dashboard:
    proxy-stream-allow-list: '*'        
        
management:
  endpoints:
    web:
      base-path: /
      exposure:
        include: '*'
3. Creating a separate config Java class:
package com.ibm.drama.controller;

import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.netflix.hystrix.contrib.metrics.eventstream.HystrixMetricsStreamServlet;

@Configuration
public class HystrixConfig {

    @Bean
    public ServletRegistrationBean<HystrixMetricsStreamServlet> getServlet() {
        HystrixMetricsStreamServlet streamServlet = new HystrixMetricsStreamServlet();
        ServletRegistrationBean<HystrixMetricsStreamServlet> registrationBean = new ServletRegistrationBean<HystrixMetricsStreamServlet>(streamServlet);
        registrationBean.setLoadOnStartup(1);
        registrationBean.addUrlMappings("/actuator/hystrix.stream");
        registrationBean.setName("hystrix.stream");
        return registrationBean;
    }
}
