its works but i got org.springframework.orm.jpa.JpaSystemException: More than one row with the given identifier was found error

问题

my entity class is mentioned below:-

    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")

    }
    OrderDownload that = (OrderDownload) o;
    return udId.equals(that.udId);
}

@Override
public int hashCode() {

    return udId.hashCode();
}

}

and there is a toPredicate() in Specification class as mention below:-

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));
    }
}

}

i'm getting its works but i got org.springframework.orm.jpa.JpaSystemException: More than one row with the given identifier was found: OrderDownload(udId=null, dwnReqDt=null, dwnStatus=null, optyId=1-7RV24-105)
