Posting this to complete @Srik's answer.

You can use the JsonFormat class provided by Protobuf. Simply create a JsonParser object and parse the json string into a builder for the protobuf message. Below is a small snippet

private MyProtobufMessage parseJson(String jsonString) {
    JsonParser jsonParser = new JsonParser();
    MyProtobufMessage.Builder messageBuilder = MyProtobufMessage.newBuilder();

   JsonFormat.parser().usingTypeRegistry(TypeRegistry.getEmptyTypeRegistry()).merge(jsonString, messageBuilder);
    return message.build();
}
