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!!!!!!!
