SpringBoot2.1.9RELEASE配置hystrix-dashboard

2.0以上的版本配置hystrix-dashboard和之前的有所差別

1.導入依賴

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.9.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

   <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
        </dependency>      

2.修改啟動類

@EnableEurekaClient
@SpringBootApplication
@EnableHystrixDashboard
public class SemaPhoreApplicationBreaker {

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

}      

3.增加一個配置類 否則通路儀表盤時404

package com.fpy.config;

import com.netflix.hystrix.contrib.metrics.eventstream.HystrixMetricsStreamServlet;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;

@org.springframework.context.annotation.Configuration
public class Configuration {

    @Bean
    public ServletRegistrationBean<HystrixMetricsStreamServlet> getServlet() {
        HystrixMetricsStreamServlet hystrixMetricsStreamServlet = new HystrixMetricsStreamServlet();
        ServletRegistrationBean<HystrixMetricsStreamServlet> servletRegistrationBean = new ServletRegistrationBean();
        servletRegistrationBean.setServlet(hystrixMetricsStreamServlet);
        servletRegistrationBean.addUrlMappings("/hystrix.stream");
        servletRegistrationBean.setName("HystrixMetricsStreamServlet");
        return servletRegistrationBean;
    }
}      

4.可以啟動服務 通路接口了

5.通路時出現了n個ping 不要害怕 他在等待你通路接口 以便進行資料分析

6.通路接口後 就會出現 如下的内容 一個json資料 可以進入到可視化界面進行檢視

7.可視化界面 ​​http://localhost:1002/hystrix​​

再次重新整理接口就會有不一樣的效果産生
