SpringBoot2.1.9RELEASE配置hystrix-dashboard

2.0以上的版本配置hystrix-dashboard和之前的有所区别

1.导入依赖

<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.修改启动类

@EnableEurekaClient
@SpringBootApplication
@EnableHystrixDashboard
public class SemaPhoreApplicationBreaker {

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

}      

3.增加一个配置类 否则访问仪表盘时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.可以启动服务 访问接口了

5.访问时出现了n个ping 不要害怕 他在等待你访问接口 以便进行数据分析

6.访问接口后 就会出现 如下的内容 一个json数据 可以进入到可视化界面进行查看

7.可视化界面 ​​http://localhost:1002/hystrix​​

再次刷新接口就会有不一样的效果产生
