auditing - ObjectRemoved (JaVers) 类型的变化是什么意思？

Question

JaVers 用户，

我试图了解 JaVers 比较的基础知识，但无法弄清楚！

我创建了一个非常基本的 MyObject 类，如下所示：

public class MyObject {

    @Id
    private int id;
    private String name;
    private String remark;

    public MyObject() {
        id=-1;
        name = "";
        remark = "";
    }

    public MyObject(int id)
    {
        this.id = id;
        name = "";
        remark = "";
    }

    public MyObject(int id, String name, String remark) {
        this.id = id;
        this.name = name;
        this.remark = remark;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getRemark() {
        return remark;
    }

    public void setRemark(String remark) {
        this.remark = remark;
    }
}

我创建了两个 MyObject 之类的：

MyObject firsto = new MyObject(1);
MyObject secondo = new MyObject(2);

接下来我做一个：

Diff diff = javers.compare(firsto,secondo);
System.out.println(diff);

输出如下所示：

Diff:
1. NewObject{globalId:'mypackage.MyObject/2'}
2. ObjectRemoved{globalId:'mypackage.MyObject/1'}

我的问题是这个输出中 ObjectRemoved 的确切含义是什么？无法找到任何有关此的文档，抱歉！

问候，杰拉德

NewObject 表示一个对象仅存在于差异的右侧。ObjectRemoved - 仅在左侧。由于您已将您的类映射为实体，MyObject(1)并且 newMyObject(2)是两个不同的对象，因此您无法比较它们。尝试将 MyObject 映射为 ValueObject
