All Implemented Interfaces:

org.springframework.beans.factory.Aware, GatewayFilterFactory<JsonToGrpcGatewayFilterFactory.Config>, Configurable<JsonToGrpcGatewayFilterFactory.Config>, ShortcutConfigurable, org.springframework.context.ApplicationEventPublisherAware

public class JsonToGrpcGatewayFilterFactory
extends AbstractGatewayFilterFactory<JsonToGrpcGatewayFilterFactory.Config>

This filter takes a JSON payload, transform it into a protobuf object, send it to a given gRPC channel, and transform the response back to JSON. Making it transparent for the consumer that the service under the gateway is a gRPC one.
