##5、hystrix.stream @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; } ##6、@RefreshScope 参数刷新

在使用参数的类上添加注解 @RefreshScope @Value("${app}")获取参数配置

##7、Feign调用和熔断配置 @FeignClient(value = "stock",fallback = StockServiceHystric.class)
