断路器:
hystrix.command.default.circuitBreaker.requestVolumeThreshold(当在配置时间窗口内达到此数量的失败后,进行短路。默认20个)
#For example, if the value is 20, then if only 19 requests are received in the rolling window (say a window of 10 seconds) the circuit will not trip open even if all 19 failed.
hystrix.command.default.circuitBreaker.sleepWindowInMilliseconds(短路多久以后开始尝试是否恢复,默认5s)
hystrix.command.default.circuitBreaker.errorThresholdPercentage(出错百分比阈值,当达到此阈值后,开始短路。默认50%)
fallback:
hystrix.command.default.fallback.isolation.semaphore.maxConcurrentRequests(调用线程允许请求HystrixCommand.GetFallback()的最大数量,默认10。超出时将会有异常抛出,注意:该项配置对于THREAD隔离模式也起作用)
