Spring Zuul return 502

Question

У меня есть проект шлюза Spring Boot, который использует Zuul для направления запросов на внутренние службы. Эти службы открыты с использованием Eureka.

Это работает для большинства сценариев. Однако есть несколько длинных запросов, которые возвращают 502 со шлюза. Основная услуга фактически завершает запросы. И запрос на шлюз остается открытым в течение времени.

Оба запроса довольно длинные. Один выполняется небольшой процесс, который занимает около 5-10 секунд. Другая - загрузка файла. Оба запроса: POST методы, которые не возвращают тело. Это повлияет на Зуула?

Это трассировка стека из журналов.

Вот соответствующие разделы наших журналов.

zuul.servletPath=/files 
zuul.routes.media.path=/media/** 
zuul.routes.media.serviceId=media-upload-service 
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=30000 
hystrix.command.media.execution.isolation.thread.timeoutInMilliseconds=1800000 
ribbon.eureka.enabled=true 
ribbon.ConnectTimeout=3000 
ribbon.ReadTimeout=30000 
media.ribbon.ReadTimeout=1800000 

Мы используем Spring Boot 1.4.1 и Spring Cloud Camden.

Как я могу предотвратить переход Spring Gateway на эти запросы?

Answer 1

Представляется, что проблема заключалась в том, что я использовал Zuul маршрут имя в Hystrix вместо службы имени Eureka.

Я изменил:

hystrix.command.media.execution.isolation.thread.timeoutInMilliseconds=1800000 

в

hystrix.command.media-upload-service.execution.isolation.thread.timeoutInMilliseconds=1800000 

Таким образом, он соответствует ServiceID от:

zuul.routes.media.serviceId=media-upload-service
