我有一组使用JHipster创建并配置有Okta OAuth2自动认证的微服务。
我还添加了与RabbitMQ消息服务的集成，因此该服务之一在某些事件上生成消息，而另一项使用这些消息来更新其数据库。
现在，第二项服务要完全更新其数据，需要我想通过FeignClient调用的第三项服务提供的信息，但由于以下堆栈而失败：
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scopedTarget.oauth2ClientContext': Scope 'request' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton; nested exception is 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.

我认为问题在于Feign执行不是从Web请求开始的，因此上下文中没有身份验证信息...对吗？
还有其他方法可以在服务之间获取我的数据吗？
答案 0 :(得分：1)
问题是您的TokenRelayRequestInterceptor试图从当前线程绑定的安全上下文中解析身份验证信息。
很明显，当您处于使用者线程中时，您没有此类信息（至少是默认情况下），因此解析失败。
您可以做的事情如下：
在使用者方面，您可以使用拦截器所需的信息来手动设置SecurityContext，也可以在使用者方面忘记拦截器，然后手动提供第三项服务所需的数据（我想这只是一个{{ 1}}标头）。
更新 您还可以在第三个服务中创建一个内部端点，该端点完全不需要任何身份验证，外部人员无法访问它。
