How to convert a proto message to and from JSON (Java)?

[omid pourhadi]

Hi,

I have a simple proto message in grpc

message Person{

  int32 id = 1;

  string firstName = 2;

}

How can I convert it into Json after generating code for java language and convert json to Person?

for example :

Person.toJson();

{"id":, "firstName": "test"}

Or

Person.fromJson(json);

let me know if there is any solution rather than https://grpc.io/blog/grpc-with-json

Thanks

Hi, 

I have been using this https://developers.google.com/protocol-buffers/docs/reference/java/com/google/protobuf/util/Jsonformat. It is working for me to convert grpc messages to json and Jason to grpc message.

Thanks

Mahesh is right, that is the correct way.  

Also, I wrote the grpc-with-json article.  It was meant to show how to avoid any Protobuf dependencies.   If you want to use JsonFormat (which I also recommend), there is an example client and server here: https://github.com/grpc/grpc-java/tree/v1.15.0/examples/src/main/java/io/grpc/examples/advanced
