ERRORE: ORA-02289: la sequenza non esiste - org.hibernate.exception.SQLGrammarException: impossibile estrarre ResultSet

Sto creando un'applicazione di ibernazione di base per la tabella dei dipendenti in cui sto aggiungendo, aggiornando, eliminando e visualizzando il record con l'aiuto della classe ManageEmployee.ERRORE: ORA-02289: la sequenza non esiste - org.hibernate.exception.SQLGrammarException: impossibile estrarre ResultSet

In realtà, ManageEmployee è la mia classe di test e sto utilizzando il file Employee.java e Employee.hbm.xml per fare sopra le cose.

Dettagli: di database: Oracle 11 g versione Hibernate: hibernate-release-4.3.8.Final Java Version: Java 1.8

Impiegato Tabella Dettagli:

USER_ID NUMERO (15,0) No 1 1
FIRST_NAME VARCHAR2 (20 BYTE) Sì 2
LAST_NAME VARCHAR2 (20 BYTE) Sì 3
STIPENDIO NUMERO (10,0) Sì 4

Registro errori: è possibile vedere nel registro che l'errore è in arrivo 3 volte perché sto aggiungendo l'oggetto Employee 3 volte nella classe ManageEmployee.java con il metodo addEmployee (...) quindi presumo che il problema sia con il generatore di sequenze per colonna id.

Qui sto usando il generatore naive. , ad es. Numero intero empID1 = ME.addEmployee ("Zara", "Ali", 1000);

Mostra alla classe Employee prega; questo errore si verifica quando si inserisce un nuovo ID/riga nella tabella e non è stata creata una sequenza nella classe del modello (Dipendente), quindi la sospensione non può creare la nuova riga perché non conosce l'ID da inserire. – Asura

Sembra che '' si aspetti che venga creata una sequenza, magari guardate i documenti riguardo a quale implementazione Oracle di quale generazione "nativa" fa in questa circostanza? – BretC

@Asura ho modificato la domanda. l'ultimo è la classe Employee – user2682305

classe Employee manca un generatore sequenza in modo Sospensione non può inserire la riga. dovrebbe essere qualcosa di simile che aumentano la colonna conteggio id da 1:

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

, quindi è necessario cambiare anche la classe del generatore? Voglio dire "nativo" a "sequenza" – user2682305

il modo in cui ho postato era con l'annotazione di primavera le mie scuse si sta facendo il mapping utilizzando un file xml. Il motivo per cui si ottiene questo errore nel file xml è perché si aspetta un nome per la sequenza altrimenti tenta di farlo da solo a meno che il file di configurazione non sia impostato correttamente. Il nome dovrebbe essere il nome che hai dato alla sequenza nel Database.http: //www.java4s.com/hibernate/generators -in-hibernate/ – Asura

Ho avuto quelle stesse righe ancora lo stesso errore. –

dopo leggere su Oracle sequences e il loro funzionamento, così come telling Hibernate that you are using a SEQUENCE (sezione 5.1.2.2.4), piuttosto che un generatore nativo , Ho corretto i miei errori.

Ho creato una sequenza nel database Oracle tramite la query seguente e aggiornato my hbm.file xml

CREATE SEQUENCE TAB_CUSTOMER_SEQ 
 
START WITH 1 
 
MAXVALUE 999999999999999999999999999 
 
MINVALUE 1 
 
NOCYCLE 
 
CACHE 20 
 
NOORDER;

<id name="user_id" type="int" column="user_id"> 
 
      <generator class="sequence">

      </generator>   
 
     </id>

Ho pensato che volessi creare la sequenza in Java. –
