テーブルを作成しているのにエントリを作成していないHibernate？

Question

私はHibernateへの接続が自分のコードで動作していることをテストしようとしているので、テーブルに新しいエンティティを作成する基本的な方法を設定しました。コードを実行すると、エラーは表示されず、最初に実行したときにHibernateはテーブルを正常に作成しましたが、行はテーブルに作成されていません。なぜこれが起こっているのかも知れませんか？ペーストされたユーザークラスと、ログを作成するためのコード。

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); 
} 

Userクラス：

@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; 
    } 
}

。あなたはする必要があります：

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(); 
}
