问题描述
我使用了proto3_optional，并在“可选”字段中缺少此xxCase（）方法。有解决方法吗？
生成的消息类“ muni.model.Model $ Person”缺少方法“ getId 案例”
NoSuchMethodException：muni.model.Model $ Person.getId Case（）
注意：我需要保留hasXX（）方法用于验证对象，而JsonFormat.printer（myproto）用于反序列化。
原型对象
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;
}

在涉及反序列化的任何地方都会发生错误
例如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);
}
}
...
}
