Problem returning stream of responses from gRPC service to RESTful client

Question

I am attempting to write a set of services that will provide a REST interface to external clients, while using gRPC/protobuf for inter-service communication internally. Spri

Answer 1

In may case i have: .... response.setMessageCode(0).setResponseMessage("string message"); .... that never return to client.

I change this to: ... APIResponse response = APIResponse.newBuilder().setResponseMessage(localidad.toString()).build(); ...

Without ".setMessageCode(0)"... and it works!

Answer 2

According to the Gateway log, it looks like jackson is having trouble converting proto to json.

can you try com.googlecode.protobuf.format.JsonFormat? I am not spring user, but there should be API for custom serialization. or, you can add custom serialization to jackson using JsonFormat but it sounds little weird.
