hystrix实战总结;

HystrixCircuitBreaker 有三种状态 :

断路器默认是20个请求失败才打开短路器,可以进行配置:

CLOSED :关闭

OPEN :打开

HALF_OPEN :半开

1、接口正确,接口报超时;

2、springboot2.0后使用hystrix的监控必须得加:因为默认不是hystrix.stream

@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;
    }

  加上后监控器才可以访问

3、hystrix的的fallback触发机制详细介绍,这个博文非常好!!!!!!!
