问题
I used the proto3_optional, and getting this xxCase() method missing on field that are 'optional'. Is there a workaround for this?
Generated message class "muni.model.Model$Person" missing method "getIdCase"
NoSuchMethodException: muni.model.Model$Person.getIdCase()
Note: I need to retain hasXX() method working for validating objects, and JsonFormat.printer(myproto) for deserializing.
Proto object
message Person{
//Output only
optional string id = 3; // "muni.model.Model$Person" missing method "getIdCase"
optional string firstName = 4; // optional added to test hasFirstName()
optional string lastName = 5;
optional string email = 6;
optional string phone1 = 7;
optional string phone2 = 8;
PostalAddress address = 9; //For objects no need for optional, hasAddress() works
bool dirty = 10;//for boolean getDirty() default behavior works, no need for optional
//Output only
google.protobuf.Timestamp createTime = 1;
//Output only
google.protobuf.Timestamp updateTime = 2;
}

Error happens wherever deserializing is involved
e.g jsonprint, System.out.println(myproto).
import com.google.protobuf.Message;
import com.google.protobuf.MessageOrBuilder;
import com.google.protobuf.util.JsonFormat;
public class ProtoUtil {
public static <T extends Message> String toJson(T obj){
try{
return JsonFormat.printer().print(obj);
}catch(Exception e){
throw new AppException("Error converting Proto to json", e);
}
}
