Spring Boot + gRPC Error Handling - Using Trailer Metadata

In this tutorial we will be implementing spring boot + gRPC Error Using Metadata Trailer. In gRPC, metadata trailers are a way to provide additional information or context at the end of an RPC (Remote Procedure Call) response or response stream. Trailer Metadata are sent as part of the RPC's trailing metadata-metadata that is sent after the main response data. https://www.javainuse.com/boot/grpc8
