[grpc-java] how to get request class info in ServerInterceptor

[최상용]

I hope get request class Info in ServerInterceptor

Is it possible ?

If it is possible, tell me way

example code

class ExampleInterceptor implements ServerInterceptor {

        @Override

    public <ReqT, RespT> ServerCall.Listener<ReqT> interceptCall(
            ServerCall<ReqT, RespT> call,
            Metadata headers,
            ServerCallHandler<ReqT, RespT> next
    ) {
        Class<ReqT>  class =  ?

        return next.startCall(call, headers);
    }

}

I seem to find solution.

I share for people who same trouble as me

class ExampleInterceptor implements ServerInterceptor {

        @Override

    public <ReqT, RespT> ServerCall.Listener<ReqT> interceptCall(
            ServerCall<ReqT, RespT> call,
            Metadata headers,
            ServerCallHandler<ReqT, RespT> next
    ) {

        MethodDescriptor.ReflectableMarshaller  reflectableMarshaller = (MethodDescriptor.ReflectableMarshaller) request.getMethodDescriptor().getRequestMarshaller()
        Class<ReqT> requestClassInfo = reflectableMarshaller.getMessageClass()
        return next.startCall(call, headers);
    }

}
