启动Spring Cloud Hystrix仪表板示例时遇到问题

Question

Trying to launch a Hystrix dashboard and receiving an error upon launch. Following the example provided via github as the base. Have not made any changes to the code really. Just trying to launch.

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Configuration
@ComponentScan
@EnableAutoConfiguration
@EnableHystrixDashboard
public class HystrixDashboardApplication {

    public static void main(String[] args) {
        SpringApplication.run(HystrixDashboardApplication.class, args);
    }

}

@Controller
class HystrixDashboardController {

    @RequestMapping("/")
    public String home() {
        return "forward:/hystrix/index.html";
    }

}

Below is the error being reported:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name      'restTemplate' defined in class path resource [org/springframework/cloud/netflix/ribbon/RibbonAutoConfiguration.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [org.springframework.cloud.netflix.ribbon.RibbonInterceptor]: : Error creating bean with name 'ribbonInterceptor' defined in class path resource [org/springframework/cloud/netflix/ribbon/RibbonAutoConfiguration.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [org.springframework.cloud.client.loadbalancer.LoadBalancerClient]: : Error creating bean with name 'loadBalancerClient': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.springframework.cloud.netflix.ribbon.SpringClientFactory org.springframework.cloud.netflix.ribbon.RibbonLoadBalancerClient.clientFactory; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.cloud.netflix.ribbon.SpringClientFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

I have tried both spring-cloud-starters 1.0.0.BUILD-SNAPSHOT & 1.0.0.M1.

Answer 1

The workaround for now is to add @EnableEurekaClient .

I reproduced and worked around the issue here: https://github.com/spencergibb/communityanswers/tree/so26450251

I have raised issue #35

Answer 2

I am using Spring boot 2.1.5 release.

Faced same issue.

Tried to launch hystrix dashboard using below url -

http://localhost:8082/hystrix.html

but it didn't work then I tried

http://localhost:8082/hystrix

and it worked.
