如何将proto Builder转换为java Constructor？

Question

我想将原始反序列化的Builder转换为java Constructor，它需要处理wrapper类。如果没有分配，它将变为NULL。

1。使用反射（问题：反射性能差）https://github.com/singgel/protobuf-converter 2.一对一地使用构造函数（问题：重复编码过多）

例如：原始

syntax = "proto3";

import "google/protobuf/wrappers.proto";
option java_outer_classname = "PeopleProto";

message People {
    int32 personId = 1;
    string personName = 2;
    google.protobuf.StringValue sex = 3;
    repeated string address = 4;
}

java

public class People {

    private int personId;

    private String personName;

    private String sex;

    List<String> address;

    ...
}

byte[] bb = ...;
People people = InterClassName.parseFrom(bb);
