        return "fin/category";

 }

COACategoriesModel と COAMaintenanceModel の間には 1 対多の関係があります。AS obj_coacs.AddCOACategories(model1) はテーブルにトランザクションを追加し、obj_coams.AddCOAMaintenance (アカウント) で例外が発生した場合、すべてのトランザクションをロールバックしません。

これを制御する方法。すべてのオブジェクトがトランザクションをテーブルに正常に挿入したら、完全なトランザクションをコミットします。

現在のシーンで最も簡単な方法は何ですか

注釈のcascade要素の値を指定します。@OneToManyこれにより、が保存されCOAMaintenanceModelたときに が永続化されます。CAOCategoriesModelデフォルトでは、例外がスローされるかどうかに応じて、トランザクションは適切にコミットおよびロールバックする必要があります。

@Entity
@Table(name = "COACATEGORIES")
public class COACategoriesModel {

    /* Code ommitted */

    @OneToMany(mappedBy="categoryId", cascade=CascadeType.All)
    private List<COAMaintenanceModel> obj = null;

    /* Code ommitted */
