SpringCloud-Hystrix的DashBoard仪表盘功能笔记

1.父工程pom.xml中引入actuator依赖

            org.springframework.boot
            spring-boot-starter-actuator
        

2.服务调用方application.yml中添加相关配置

management:
  endpoints:
    web:
      exposure:
        include: "*"
  endpoint:
    health:
      show-details: always

3.服务调用方注册监控Servlet

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

4.创建一个新的工程，仪表盘项目，发布到注册中心

server:
  port: 9000
eureka:
  instance:
    hostname: localhost
    prefer-ip-address: true
    instance-id: ${spring.cloud.client.ip-address}:${spring.application.name}:${server.port}:@project.version@
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka/
    register-with-eureka: true
    fetch-registry: true
spring:
  application:
    name: dashboard

@SpringBootApplication
@EnableHystrixDashboard
public class DashBoardApplication {
    public static void main(String[] args) {
        SpringApplication.run(DashBoardApplication.class,args);
    }
}

        
            org.springframework.cloud
            spring-cloud-starter-netflix-hystrix
        
        
        
            org.springframework.cloud
            spring-cloud-starter-netflix-hystrix-dashboard
        
        
            org.springframework.cloud
            spring-cloud-starter-netflix-eureka-client
        

5.启动仪表盘项目，访问项目IP+端口/hystrix
