Hibernate-Tabelle erstellen, aber keinen Eintrag erstellen?

Question

Ich versuche zu testen, dass meine Verbindung zu Hibernate in meinem Code funktioniert, so dass ich eine grundlegende Methode zum Erstellen einer neuen Entität in einer Tabelle einrichten. Wenn ich den Code ausführe, sehe ich keinen Fehler, und als ich das erste Mal ausgeführt habe, hat Hibernate die Tabelle erfolgreich erstellt, aber die Zeile wird nicht in der Tabelle erstellt. Wer weiß, warum das passieren könnte? Eingefügte Benutzerklasse und Code zum Erstellen von unten sowie von Protokollen.

public static void main(String[] args) { 
    Session session = SessionFactoryUtil.getSessionFactory().getCurrentSession(); 
    session.beginTransaction(); 
    User user = new User(); 
    user.setPassword("abcd"); 
    user.setStatus(UserStatus.OFFLINE); 
    user.setUserName("testuser"); 
    session.save(user); 
} 

Benutzerklasse:

@Entity 
    @Table(name="USERS") 
    public class User { 

    @Id 
    @GeneratedValue(strategy=GenerationType.AUTO) 
    @Column(name="USER_ID") 
    private String userId; 

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

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

    @Enumerated(EnumType.STRING) 
    @Column(name="STATUS") 
    private UserStatus status; 

    public String getUserId() { 
     return userId; 
    } 

    public void setUserId(String userId) { 
     this.userId = userId; 
    } 

    public String getUserName() { 
     return userName; 
    } 

    public void setUserName(String userName) { 
     this.userName = userName; 
    } 

    public String getPassword() { 
     return password; 
    } 

    public void setPassword(String password) { 
     this.password = password; 
    } 

    public UserStatus getStatus() { 
     return status; 
    } 

    public void setStatus(UserStatus status) { 
     this.status = status; 
    } 
}

Answer 1

Sie Ihre Transaktion nicht zu begehen. Sie müssen Folgendes tun:

public static void main(String[] args) { 
    Session session = SessionFactoryUtil.getSessionFactory().getCurrentSession(); 

    Transaction tx = session.beginTransaction(); 

    User user = new User(); 
    user.setPassword("abcd"); 
    user.setStatus(UserStatus.OFFLINE); 
    user.setUserName("testuser"); 

    session.save(user); 
    tx.commit(); 
    session.close(); 
}
