Сервис к сервису связи через Resttemplate с облаком Spring (Oauth 2)
Привет, я пытаюсь вызвать службу весенней загрузки из другого сервиса через Rest-шаблон. я использую консул как сервисный сервис сейчас Service1->rest ->Service2
Я не хочу, чтобы эта связь через Zuul service1 могла напрямую вызывать service2, но лента должна обнаружить вторую службу через консула. все работает нормально, но когда я пытаюсь вызвать service1 на service2, я получаю ниже исключения на service1
java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

Если вы сконфигурируете свою HystricCommand для выполнения в том же потоке, он сможет увидеть детали аутентификации OAuth2 в рамках сеанса, необходимые для OAuth2RestTemplate:
@HystrixCommand(commandProperties={
@HystrixProperty(name = execution.isolation.strategy, value = "SEMAPHORE")
})
Остерегайтесь, вы теряете возможности тайм-аута HystrixCommands (см. Примечание под https://github.com/Netflix/Hystrix/wiki/How-it-Works).
