ValueObject or DTO

A DTO or ValueObject should be designed like this:

package com.carbook.ratings.json.upsert;

import com.fasterxml.jackson.annotation.JsonCreator;
import com.fasterxml.jackson.databind.annotation.JsonDeserialize;
import com.fasterxml.jackson.databind.annotation.JsonPOJOBuilder;

import lombok.NonNull;
import lombok.Value;

@SuppressWarnings("unused")
@Value
@JsonDeserialize(builder = ApiCreateReviewItem.Builder.class)
public class ApiCreateReviewItem {
    private final String id;
    private final String type;
    private final Long rating;

    @JsonCreator
    @lombok.Builder(builderClassName = "Builder", builderMethodName = "newBuilder", toBuilder = true)
    private ApiCreateReviewItem(@NonNull String id, @NonNull String type, @NonNull Long rating) {
        this.id = id;
        this.type = type;
        this.rating = rating;
    }

    @JsonPOJOBuilder(withPrefix = "")
    public static class Builder {
    }
}

The lombok will generate a class like this:

//
// Source code recreated from a .class file by IntelliJ IDEA
// (powered by Fernflower decompiler)
//
