Question

我的实体类在下面提到：-

public class ExportOrderInfo implements Serializable {

private static final long serialVersionUID = 1L;

@OneToOne
@NotFound(action = NotFoundAction.IGNORE)
@Cascade(org.hibernate.annotations.CascadeType.ALL)
@JoinColumn(name = "CURRENT_ORDER_NUMBER")
@JoinColumn(name = "EXPIRE_DATE")
@JoinColumn(name = "ORG_CODE")
@JoinColumn(name = "STIR_CD")
private ExportOrderDetailInfo orderDetail;

@OneToOne
@NotFound(action = NotFoundAction.IGNORE)

private OrderDownload orderDownload;


@Override
public boolean equals(Object o) {

    if (this == o) {
        return true;
    }
    if (o == null || getClass() != o.getClass()) {
        return false;
    }
    ExportOrderInfo that = (ExportOrderInfo) o;
    if (!currentOrderNumber.equals(that.currentOrderNumber)) {
        return false;
    }
    if (!orgCode.equals(that.orgCode)) {
        return false;
    }
    if (!Objects.equals(stirCd, that.stirCd)) {
        return false;
    }
    return Objects.equals(expireDate, that.expireDate);
}

@Override
public int hashCode() {

    int result = currentOrderNumber.hashCode();
    result = 31 * result + orgCode.hashCode();
    result = 31 * result + (stirCd != null ? stirCd.hashCode() : 0);
    result = 31 * result + (expireDate != null ? expireDate.hashCode() : 0);
    return result;
}

}

public class OrderDownload implements Serializable {

private static final long serialVersionUID = 3838097352824067548L;

@Id
@Column(name = "UD_ID")
private String udId;

@Column(name = "DWN_REQ_DT")
private Date dwnReqDt;

@Column(name = "DWN_STATUS")
private String dwnStatus;

@Column(name = "OPTY_ID")
private String optyId;

@Override
public boolean equals(Object o) {

    if (this == o) {
        return true;
    }
    if (o == null || getClass() != o.getClass()) {
        return false;
    }
    OrderDownload that = (OrderDownload) o;
    return udId.equals(that.udId);
}

@Override
public int hashCode() {

    return udId.hashCode();
}

}

并且在规范类中有一个toPredicate（），如下所述：-

public Predicate toPredicate(Root<ExportOrderInfo> root, CriteriaQuery<?> criteriaQuery, CriteriaBuilder builder) {

    if(beginningOfQuarter != null && endOfQuarter != null){
        criteriaQuery.distinct(true);
        root.join("orderDetail", JoinType.LEFT);
        root.join("orderDownload", JoinType.INNER);
        return builder.and(builder.equal(root.<String>get(randomColumnName), valueToSearchFor) , builder.isNotNull(root.get("optyId")));
    }else{
        criteriaQuery.distinct(true);
        root.fetch("orderDetail", JoinType.LEFT);
        root.fetch("orderDownload", JoinType.LEFT);
        return builder.and(builder.equal(root.<String>get(randomColumnName), valueToSearchFor));
    }
}

}

我正在工作，但是我得到了org.springframework.orm.jpa.JpaSystemException：找到了多个具有给定标识符的行：OrderDownload（udId = null，dwnReqDt = null，dwnStatus = null，optyId = 1 -7RV24-105）
