Overriding default field names in JSON serialization

[David Koch]

Hello,

Using the JSON printing/parsing utilities in proto3 - is it possible to override the default JSON field names generated? If so, how can this be achieved?

I use the standard way to instantiate the printer and parser for now:

private static JsonFormat.TypeRegistry registry = JsonFormat.TypeRegistry.newBuilder()

      .add(MyClass.getDescriptor()).build();

private static JsonFormat.Printer printer = JsonFormat.printer().usingTypeRegistry(registry);

private static JsonFormat.Parser parser = JsonFormat.parser().usingTypeRegistry(registry);

Thanks,

Regards,

David

You can use the json_name field option to specify the name you want to use in JSON. For example:

message Foo {

  string id = 1 [json_name = "@id"];

}

The JSON format will then be:

{

  "@id": "..some value..."

}
