我正在使用 Gilead 将我的实体保存在我的 GWT 项目中，我也使用休眠注释。我的问题出在我的 onetomany 关联上。这是我的 User 类，它包含对 FileLocations 列表的引用

@Entity
@Table(name = "yf_user_table")
public class YFUser implements Serializable {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "user_id",nullable = false)
private int userId;
@Column(name = "username")
private String username;
@Column(name = "password")
private String password;
@Column(name = "email")
private String email;

@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY) @JoinColumn(name="USER_ID") private List fileLocations = new ArrayList();

这是我的文件位置类

@Entity
@Table(name = "fileLocationTable")
public class FileLocation implements Serializable {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "locationId", updatable = false, nullable = false)
private int ieId;
@Column (name = "location")
private String location;

@ManyToOne(fetch=FetchType.LAZY) @JoinColumn(name="USER_ID", nullable=false) private YFUser uploadUser;

当我将这些数据保存在普通桌面应用程序中时，它可以正常工作，创建表，我可以向其中添加和存储数据。但是当我尝试将数据保存在我的 gwt 应用程序中时，我会遇到错误，我会将它们显示得更低。这是我的扩展 PersistentRemoteService 的 ServiceImpl 类。

public class TestServiceImpl extends PersistentRemoteService implements TestService {

public static final String SESSION_USER = "UserWithinSession";

public TestServiceImpl(){

    HibernateUtil util = new HibernateUtil();
        util.setSessionFactory(com.example.server.HibernateUtil
                .getSessionFactory());

    PersistentBeanManager pbm = new PersistentBeanManager();
    pbm.setPersistenceUtil(util);
    pbm.setProxyStore(new StatelessProxyStore());

    setBeanManager(pbm);
}

    @Override
public String registerUser(String username, String password, String email) {
    Session session = com.example.server.HibernateUtil.getSessionFactory().getCurrentSession();
    session.beginTransaction();

    YFUser newUser = new YFUser();
    newUser.setUsername(username);newUser.setPassword(password);newUser.setEmail(email);

    session.save(newUser);
    session.getTransaction().commit();

    return "Thank you For registering "+ username;

}

这是我得到的错误。当我删除我的 onetoManyRelationship 并在我放入会话工厂时构建我的会话工厂时，错误消失了，它在 hibernate Util 中的 buildsessionfactory 行上，它抛出了这个异常。我的休眠实用程序类也可以。这是错误 java.lang.NoSuchMethodError: javax.persistence.OneToMany.orphanRemoval()Z

从构建路径中删除ejb3-persistance.jar和删除它解决了我的问题，它也可能对你有用。

也不要忘记添加hibernate-jpa-2.0-api-1.0.0.Final.jar到您的构建路径。

使用 javax.persistence api 2.0，但不是 1.0 之一

只需添加评论以可能帮助其他面临此问题的人。也可能是您的应用程序服务器提供了一个“遮盖”休眠版本的 JPA 版本。对我来说，我必须做这样的事情：

mkdir /usr/local/resin/libremoved
mv /usr/local/resin/lib/jpa* /usr/local/resin/libremoved/

此外，如果您使用“完整的”Java EE API 库（例如同时包含 JPA 和其他 API，如 Servlet 等的库）进行编译，请确保完整的库比特定的 JPA 2.0 库位于类路径的下方
