如何使用 Javers 区分同一实体 class 但具有不同 Id 的两个对象

Question

来自Javers.org

Each Entity instance has a global identifier called InstanceId. It consists of a class name and an ID value.

Comparing strategy for Entity references is based on InstanceId and for Entity state is property-by-property.

Entity can contain ValueObjects, Entity references, Containers, Values and Primitives.

现在我想比较两个实体对象，实际上是同一个对象的两个版本，但是Javer会直接判断它们是旧对象和新对象。无法比较它们的价值。

@Entity
public class Person {
    @Id
    private Integer id;

    private String name;

    private Integer age;
}

PersonOne(1, "汤姆", 20);
PersonTwo(2,"Jerry", 18);

有没有办法比较这两个对象？

Answer 1

您可以告诉 JaVers 将这些对象作为值对象进行比较 (属性-by-属性):

javersBuilder.registerValueObject(Person.class)
