休眠列於持久性

我一直在試圖建立以登記爲目的基於EJB的註冊用戶的事務管理器不匹配 - 這是很基本的雛形，所以請不要用散列的口令等休眠列於持久性

問題予以關注我目前正在努力與從dao調用的持久化方法的列不匹配。問題的核心是事實，即hibernate試圖將作爲用戶名傳遞的值插入到ID中。

我做了find一些類似的問題解決了，但是他們是由於hibernate的自動生成的表的命名衝突，在這裏不應該這樣，因爲'Id'表被顯式地標記爲主鍵。

我非常想念爲什麼會這樣休眠，特別是因爲我之前在單一戰爭中一直使用SpringBeans並且現在相同的休眠代碼不能與獨立EJB一起工作。 ID值設置爲數據庫的表定義裏面自動生成的 - 在我道

@Stateless 
@TransactionManagement(TransactionManagementType.CONTAINER) 
public class UsersDaoImpl implements UsersDao{ 

    @PersistenceContext 
    private EntityManager em; 

    @Override 
    public void register(User user, Set<Role> roles) { 
     em.persist(user); //Line of code that results with the exception 
     user.setActive(true); 
     user.setRoles(roles); 
     em.flush(); 
    } 

    /*other methods ommitted*/ 
}

用戶實體類

16:18:59,935 INFO [stdout] (EJB default - 9) user in dao: User with id='0', name='username1', password='password1', with 0 roles 
16:18:59,965 INFO [stdout] (EJB default - 9) Hibernate: insert into public.users (password, username) values (?, ?) 
    16:18:59,970 WARN [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (EJB default - 9) SQL Error: 0, SQLState: 22003 
    16:18:59,971 ERROR [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (EJB default - 9) Bad value for type int : username1

寄存器功能。

@Entity 
@Table(name = "users", schema = "public") 
public class User implements Serializable{ 
public User(){ 
} 

public User(String username, String password){ 
    this.username = username; 
    this.password = password; 
} 


@Id 
@GeneratedValue(strategy = GenerationType.IDENTITY) 
@Column(name = "id",unique = true,nullable = false, insertable = false) 
private int id; 

@Column(name ="username", unique = true,nullable = false) 
private String username; 

@Column(name ="password", nullable = false) 
private String password; 

@Column(name = "flag", insertable = false) 
private boolean active; 
/*I have ommitted other values as they were not the part of this table*/ 
}

下面是從遠程寄存器調用JBOSS日誌：

路上，我曾試圖提出的解決方案鏈接的文章，但似乎休眠然後嘗試使用它自己的序列序列，從ID = 0開始 - 此解決方案不適用於填充數據庫，如我的。 當我使用'@ GenerationType = Identity'時，它確實使用默認值（創建時間==現在，數據庫序列中的id）創建數據庫內的實體，但上面的錯誤仍然彈出嘗試（不成功）回滾事務，甚至無需設置級聯值。這就像hibernate沒有意識到它做了適當的插入，因此放棄它。 – 2014-09-23 09:20:38

我終於設法找到解決問題的辦法。

顯然，hibernate（4.0.1Final）在沒有彈簧的情況下使用@Id註釋列的順序時出現問題。

username | password | last_login |  creation_date  | id | flag 
----------------+----------------+------------+----------------------------+----+------

@ID列必須是表中的第一列，以便hibernate正確映射它。

id | username | password | last_login |  creation_date  | flag 
----+-----------+-----------+------------+----------------------------+------
