エラー：ORA-02289：シーケンスが存在しません-org.hibernate.exception.SQLGrammarException：ResultSetを抽出できませんでした

ManageEmployeeクラスの助けを借りて、レコードを追加、更新、削除、表示する従業員テーブル用の基本的な休止状態アプリケーションを作成しています。

実際、ManageEmployeeは私のテストクラスであり、上記のことを行うためにEmployee.JavaおよびEmployee.hbm.xmlファイルを使用しています。

詳細：データベース：Oracle 11 g Hibernateバージョン：hibernate-release-4.3.8.Final Java Version：Java 1.8

従業員テーブルの詳細：

USER_ID NUMBER（15,0）いいえ1 1
FIRST_NAME VARCHAR2（20 BYTE）はい2
LAST_NAME VARCHAR2（20 BYTE）はい3
給与番号（10,0）はい4

エラーログ：EmployeeオブジェクトをaddEmployee（...）メソッドでManageEmployee.Javaクラスに3回追加しているため、エラーが3回発生していることがログでわかります。 id。

ここでは、単純なジェネレーターを使用しています。例整数empID1 = ME.addEmployee（ "Zara"、 "ALi"、1000）;

従業員クラスにはシーケンスジェネレータがないため、休止状態では行を挿入できません。 id countカラムを1増やすこのようなものでなければなりません：

@Id
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="SEQUENCE1")
@SequenceGenerator(name="SEQUENCE1", sequenceName="SEQUENCE1", allocationSize=1)
private int user_id;

Oracleシーケンス とその機能、および SEQUENCEを使用していることをHibernateに伝える （セクション5.1.2.2.4）ではなくネイティブジェネレーターを読んだ後、エラーを修正しました。

以下のクエリでOracleデータベースにシーケンスを作成し、hbm.xmlファイルを更新しました

CREATE SEQUENCE TAB_CUSTOMER_SEQ

MAXVALUE 999999999999999999999999999
