Spring Cloud коляски балансировка нагрузки не повторить в случае неудачи

2016-03-18 2 views

У меня есть следующие настройки:Spring Cloud коляски балансировка нагрузки не повторить в случае неудачи

  • Spring Cloud Eureka сервер (весна загрузка приложение с @EnableEurekaServer)
  • Весна Облако коляски (работаем на :8080)
  • 2 экземпляра одного и того же загрузочного приложения Spring Boot правильно зарегистрировались у Eureka (@EnableEurekaClient) и выставили одну конечную точку GET /configurations (работает на :80811010)

Все это работает на Java 8 + Spring Cloud 1.1.0.M5.

Вызов конечной точки REST через Sidecar по телефону :8080 работает нормально, запросы сбалансированы по нагрузке и ответы на них правильны. Если я выключение один из экземпляров 2 приложения и вызывать снова конечную точку, клиент получает эту ошибку:

{ 
    "timestamp": 1458328852272, 
    "status": 500, 
    "error": "Internal Server Error", 
    "exception": "com.netflix.zuul.exception.ZuulException", 
    "message": "Forwarding error" 
}

Бревна Sidecar показывают следующее:

Самое интересное в том, что отказ в соединении (Stale connection detected), и выполняется вызов другого экземпляра (я вижу входящий запрос), но результат по-прежнему является ошибкой. Я ожидаю, что ответ от повторного вызова будет возвращен клиенту.

Является ли это ошибкой в ​​вехе или мне не хватает какой-либо конфигурации, чтобы сделать эту работу?

Возможно, это повторение, но общая гистерезис или лента выходят из строя. Значение по умолчанию очень короткое. Есть некоторые ключи конфигурации, но я уезжаю в отпуск. Пинг меня, и я найду их на следующей неделе. – spencergibb

Вы абсолютно правы. Установка hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds: 5000 решает это. Спасибо! – Spiff

Оказалось, что Гистрикс был тем, кто выбрал время. Значение hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds: 5000, похоже, решает проблему.

Спасибо Спенсер!
