Hibernate列在持久性上不匹配

标签： hibernate postgresql ejb-3.0 hibernate-entitymanager

我一直在尝试创建基于EJB的注册用户事务管理器以进行注册 - 它是非常基本的原型，所以请不要关心未使用的密码等。

我目前正在努力解决的问题是从dao调用的持久化方法的列不匹配。问题的核心是事实，即hibernate试图将ID作为用户名传递给ID。

我做了find一些类似的问题已经解决了，但它们是由于hibernate自动生成的表的命名冲突，这不应该是这里的情况，因为'Id'表被明确标记为主键。 / p>

我很想知道为什么hibernate会以这种方式行事，特别是因为我之前在单一战争中使用过SpringBeans，现在同样的hibernate代码无法与独立EJB一起使用。

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

在我的Dao注册函数

@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*/
}

用户实体类 - 在数据库的表定义中将Id值设置为自动生成。

@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*/
}

这是来自远程注册调用的JBOSS日志：

我终于找到了问题的解决方案。

显然hibernate（4.0.1Final）在没有弹簧的情况下使用@Id带注释列的顺序有问题。

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

@ID列必须是表中第一列，以便hibernate正确映射它。

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