start up
Visit http://localhost:9001/hystrix
Start cluster 7001
Add a dependency to the 8001 provider

It is effective to use this monitoring in the fuse
Add a bean to the main startup class and put it in the IOC container
package com.kuang.springcloud;
import com.netflix.hystrix.contrib.metrics.eventstream.HystrixMetricsStreamServlet;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.context.annotation.Bean;
@SpringBootApplication
@EnableEurekaClient //在服务启动后自动注册到 eureka服务端
@EnableDiscoveryClient//服务发现~
@EnableCircuitBreaker//添加对熔断的支持 ,开启断路器
public class DeptApplicationProviderHystrix_8001 {
public static void main(String[] args) {
SpringApplication.run(DeptApplicationProviderHystrix_8001.class,args);
}
//增加一个Servlet,配合我们的监控使用
@Bean
public ServletRegistrationBean hystrixMetricsStreamServlet(){
ServletRegistrationBean registrationBean = new ServletRegistrationBean(new HystrixMetricsStreamServlet());
registrationBean.addUrlMappings("/actuator/hystrix.stream");//添加映射路径
return registrationBean;
}
}
