Hibernate创建表但不创建条目？

Question

我想测试我的连接到Hibernate是否在我的代码中工作，所以我设置了一个基本的方法来在表中创建一个新的实体。当我运行代码时，我没有看到错误，当我第一次运行它时，Hibernate成功创建了表，但表中没有创建该行。任何人都知道为什么这可能会发生？粘贴用户类和代码以创建以下以及日志。

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); 
} 

用户等级：

@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; 
    } 
}

您还没有提交你的事务。你需要做：

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(); 
}
