服务端provider

主启动

@SpringBootApplication
@EnableEurekaClient
@EnableCircuitBreaker
public class CloudProviderHystrixPayment8001 {
    public static void main(String[] args) {
        SpringApplication.run(CloudProviderHystrixPayment8001.class, args);
    }

    /**
     * 此配置是为了服务监控而配置，与服务容错本身无关，spring cloud升级后的坑
     * ServletRegistrationBean 因为 Springboot的默认路径不是“/hystrix.stream”
     * 只要在自己的项目里配置上下面的servlet就可以了
     */
    @Bean
    public ServletRegistrationBean getServlet(){
        HystrixMetricsStreamServlet streamServlet = new HystrixMetricsStreamServlet();
        ServletRegistrationBean registrationBean = new ServletRegistrationBean(streamServlet);
        registrationBean.setLoadOnStartup(1);
        registrationBean.addUrlMappings("/hystrix.stream");
        registrationBean.setName("HystrixMetricsStreamServlet");
        return registrationBean;
    }
}

监控的方法上
