单机模式

1.创建一个dashboard项目

2.引入依赖

<!--histrix依赖-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
        </dependency>
        <!--dashboard依赖-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
        </dependency>
        <!--端点依赖-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

3.在主类上打上注解@EnableHystrixDashboard开启dashboard

@SpringBootApplication
@EnableHystrixDashboard
public class SpringCloudDashboardApplication {

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

}

4.配置文件配置应用名字和端口

spring:
  application:
    name: hystrix-dashboard
server:
  port: 2001

5.启动访问http://127.0.0.1:2001/hystrix

6.在consumer增加hystirx端点的Servlet

/**
 * 用于开启histrix 端点 用于dashboard图形化
 */
@Configuration
public class HystrixStreamServletConfig {
    @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;

    }
}
