How to use google.protobuf.struct in proto file to store json result in gRPC java

I Want to Return a JSON response from server to client in gRPC.

one possible way is to convert it to string return the response then convert back to Json Object in client side, but i want to know can we do better?.

i am doing some google and found we can do it with the help of google.protobuf.struct but didn't actually find any good example.

i want an example how i can use it as JSON in java.

If you are using proto3, one option is to define a protobuf message that mirrors the JSON object you wish to populate. Then you can use JsonFormat to convert between protobuf and JSON.

Using a com.google.protobuf.Struct instead of a self-defined message can also work. There is an example shown in the similar question.
