There was a problem hiding this comment.
Please also add a streaming variant of this test.
Also I'm thinking of whether we should have an additional test for responseObserver.onError(exception) in addition to just throwing inside the method.

This PR adds the
GrpcExceptionInterceptorbean after theObservationGrpcServerInterceptorand theMetricCollectingServerInterceptorand before theExceptionTranslatingServerInterceptor.This is necessary in order to allow the later interceptor to process the error response after the exception handler is executed, more precisely to add the returned
status codeto the context/meter.Im not entirely sure but i believe this was an unintentional consequence of the added support for Order because the GrpcAdviceAutoConfiguration already had the
@Orderwith the 0 precedence it was just not doing anything.fixes #789 #1088
