啟動類註解 需要再多配置這個servlet就

@SpringBootApplication
@EnableCircuitBreaker
@EnableHystrixDashboard
public class OrderApplication {

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


	@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;
	}
}
