Hi ,
I wonder how to implement a 'global runtime exception interceptor' ,
that intercepts all server runtime exceptions , and auto
*responseObserver.onError(new
StatusRuntimeException(Status.INTERNAL.withDescription(e.getMessage())));*
so that in the server code, we don't need to try catch RuntimeException , and
write the above code in each method call.
Thanks a lot.
