java - 级联=“所有删除的孤儿”不再被引用

我一直在这里查看有关此异常的信息，但找不到解决方案，因此我认为只是粘贴我的代码，以防万一出问题。
当我尝试找到EvaluationSelectionCriteria实体时，我正在接收此异常。

Exception: org.hibernate.HibernateException: A collection with cascade="all-delete-      orphan" was no longer referenced by the owning entity instance: com.greenvalley.etendering.domain.Candidacy.evaluationSelectionCriterias


 @OneToMany(cascade = {CascadeType.ALL}, fetch = FetchType.LAZY)
@JoinColumn(name = "candidacy_id", nullable = false)
@XmlElement
@JsonIgnore
@Getter
@Setter
private List<EvaluationSelectionCriteria> evaluationSelectionCriterias = new ArrayList<>();



@ManyToOne
@JoinColumn(name = "candidacy_id", nullable = false, insertable = false, updatable = false)
@XmlTransient
@Getter
@Setter
private Candidacy candidacy;

最佳答案

我已经通过将setXX方法替换为这样来解决了这个问题

public void setEvaluationSelectionCriterias(List<EvaluationSelectionCriteria> evaluationSelectionCriterias) {

if(this.evaluationSelectionCriterias == null) { //if not already initialized
  this.evaluationSelectionCriterias = evaluationSelectionCriterias;
} else {
  this.evaluationSelectionCriterias.clear();
  this.evaluationSelectionCriterias.addAll(evaluationSelectionCriterias);
}
