Java-Ruhezustand konnte ResultSet beim Versuch, Entität

Question

hinzufügen

Ich Oracle-Datenbank verwenden und versuchen, neue Entität in "Wörter" Tabelle hinzufügen. Meine Wortmodellklasse:

@Entity(name = "Word") 
public class Word implements Serializable{ 
    public Long getId() { 
     return id; 
    } 

    @Id 
    @GeneratedValue(strategy = GenerationType.SEQUENCE, 
      generator = "etailerRaw_seq") 
    @SequenceGenerator(name = "etailerRaw_seq", 
      sequenceName = "'PRODUCT_ID_SEQ") 
    private Long id; 

    public String getName() { 
     return name; 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 

    @Column(name = "name") 
    public String name; 

    @OneToMany(fetch = FetchType.LAZY, mappedBy = "word") 
    private Set<Translation> translations; 

    public Set<Translation> getTranslations(){ 
     return translations; 
    } 
} 

Übersetzung Modell Klasse

@Entity(name = "Translation") 
public class Translation { 

    @Id 
    @GeneratedValue(strategy = GenerationType.SEQUENCE, 
      generator = "etailerRaw_seq") 
    @SequenceGenerator(name = "etailerRaw_seq", 
      sequenceName = "'PRODUCT_ID_SEQ") 
    private Long id; 


    public Long getId() { 
     return id; 
    } 

    public Word getWord() { 
     return word; 
    } 

    public Language getLanguage() { 
     return language; 
    } 

    public void setWord(Word word) { 
     this.word = word; 
    } 

    public void setLanguage(Language language) { 
     this.language = language; 
    } 

    public String getNameTranslation() { 
     return nameTranslation; 
    } 

    public void setNameTranslation(String nameTranslation) { 
     this.nameTranslation = nameTranslation; 
    } 

    public String getDescriptionTranslation() { 
     return descriptionTranslation; 
    } 

    public void setDescriptionTranslation(String descriptionTranslation) { 
     this.descriptionTranslation = descriptionTranslation; 
    } 


    @ManyToOne(fetch = FetchType.LAZY) 
    @JoinColumn(name = "Word_id", nullable = false) 
    private Word word; 

    @ManyToOne(fetch = FetchType.LAZY) 
    @JoinColumn(name = "Lang_id", nullable = false) 
    private Language language; 

    private String nameTranslation; 

    private String descriptionTranslation; 



} 

Sprachmodellklasse

@Entity(name = "Language") 
public class Language implements Serializable { 


    @Id 
    @GeneratedValue(strategy = GenerationType.SEQUENCE, 
      generator = "etailerRaw_seq") 
    @SequenceGenerator(name = "etailerRaw_seq", 
      sequenceName = "'PRODUCT_ID_SEQ") 
    private Long id; 




    @Column(name = "name") 
    private String name; 

    @OneToMany(fetch = FetchType.LAZY, mappedBy = "language") 
    private Set<Translation> translations; 

    public Set<Translation> getTranslations(){ 
     return translations; 
    } 
    public Long getId() { 
     return id; 
    } 

    public String getName() { 
     return name; 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 
} 

Wort dao Klasse

public class WordDAOBean implements WordDAO { 
    public void addWord(String description) { 
     Word word=new Word(); 
     word.setName(description); 
     Session session= HibernateUtil.getSession(); 
     session.save(word); 
     session.close(); 
    } 

    public List<Word> getAllWords() { 
     Session session= HibernateUtil.getSession(); 
     List<Word> words= session.createCriteria(Word.class).list(); 
     session.close(); 
     return words; 
    } 
} 

getAllWords Methode arbeitet successefu ll, aber wenn ich tryiing neues Wort hinzufügen, bekomme ich

auf dieser str session.save (Wort);

Answer 1

sequenzName = "'PRODUCT_ID_SEQ". Beachten Sie das einfache Anführungszeichen am Anfang des Namens der Sequenz. Danke JB Nizet
