引起：java.sql.SQLException：更新调用未设置generated-id键

Question

我正在尝试将Object存储到H2 / SQLite数据库。 Child类声明如下：

DatabaseTable(tableName = "pos_order_details", daoClass = PosOrderDetailsDaoImpl.class)
public class PosOrderDetails {

    @DatabaseField(generatedId = true, columnName = POS_ORDER_DETAILS_ID)
    private int posOrdersDetailsId;

    @SerializedName("price")
    @Expose
    @DatabaseField(columnName = PRICE)
    private double price;

子项在父项中定义如下，具有外来关系：

@SerializedName("pos_order_details")
@Expose
@ForeignCollectionField
private Collection<PosOrderDetails> posOrderDetails = new ArrayList<>(); 

大多数时候它的工作正常，但在一些随机的情况下，它给出了以下例外：

java.sql.SQLException: Unable to run insert stmt on object com.limetray.pos.models.PosOrderDetails@64031751: INSERT INTO `pos_order_details` (`price` ,`product_id` ,`product_price_id` ,`product_description` ,`product_name` ,`tag_name` ,`quantity` ,`complimentary_quantity` ,`charge_group_id` ,`user_comments` ,`pos_order_id` ) VALUES (?,?,?,?,?,?,?,?,?,?,?)
