+top message   : Error creating bean with name 'brokenRequestConsumer': Unsatisfied dependency expressed through constructor parameter 0: Error creating bean with name 'brokenRequestConsumer.RawRequestBean': 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

+root cause    : 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: In this case, use RequestContextListener or RequestContextFilter to expose the current request.
