使用 Optaplanner v7.11.0.Final 的项目上出现分数持久性问题，我升级到最新版本 (v7.25.0.Final)，但出现以下异常：
The externalObject (Etat(super=DbObject(id=11), libelle=RCD, ordre=60)) with planningId ((class plr.domain.Etat$HibernateProxy$EZnO4cSz,11)) has no known workingObject (null).
Maybe the workingObject was never added because the planning solution doesn't have a @ProblemFactCollectionProperty annotation on a member with instances of the externalObject's class (class plr.domain.Etat$HibernateProxy$EZnO4cSz).
我终于发现升级到v7.17.0.Final时不再出现异常。
自 v7.18.0.Final 以来做了哪些操作导致代码失败？
如何修复它？
编辑 ：
有关更多信息，这里是相关类
package org.optaplanner.plr.domain;
import javax.persistence.Column;
import javax.persistence.Entity;
import org.optaplanner.core.api.domain.lookup.PlanningId;
import lombok.Data;
import lombok.EqualsAndHashCode;
import lombok.ToString;
@Data
@ToString(callSuper = true)
@EqualsAndHashCode(callSuper = true)
@Entity
public class Etat extends DbObject {
@Column
private String libelle;
@Column
private int ordre;
@Override
@PlanningId
public Integer getId() {
return super.getId();
}
}
及其超类
package org.optaplanner.plr.domain;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.MappedSuperclass;
import lombok.Data;
import lombok.EqualsAndHashCode;
@MappedSuperclass
@Data
@EqualsAndHashCode
public abstract class DbObject {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
}
最后，有史以来最简单的配置:)
