使用带有 gilead 的注释通过 gwt 进行休眠时，oneToMany 关联出现错误 [英] I am getting an error with a oneToMany association when using annotations with gilead for hibernate through gwt

问题描述

我正在使用 Gilead 将我的实体保存在我的 GWT 项目中，我也使用了休眠注释.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

I'm using Gilead to persist my entities in my GWT project, im using hibernate annotations aswell. my problem is on my onetomany association.this is my User class that holds a reference to a list of FileLocations

@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")私有列表 fileLocations = new ArrayList();

@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)私人 YFUser 上传用户;

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

当我将这些数据保存在普通桌面应用程序中时，它工作正常，创建表，我可以向其中添加和存储数据.但是当我尝试在我的 gwt 应用程序中保留数据时，我会收到错误，我会将它们显示得更低.这是我的 ServiceImpl 类，它扩展了 PersistentRemoteService.

When i persist this data in a normal desktop application, it works fine , creates the tables and i can add and store data to it. but when i try to persist the data in my gwt application i get errors i will show them lower. this is my ServiceImpl class that extends PersistentRemoteService.

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 并构建我的会话工厂时，错误消失了，当我放入它时，它在 hibernate Util 中的 buildsessionfactory 行上，它抛出此异常.我的 hibernate util 类也可以.这是错误 java.lang.NoSuchMethodError: javax.persistence.OneToMany.orphanRemoval()Z

this is the error that im am getting. the error goes away when i remove my onetoManyRelationship and builds my session factory when i put it in , it on the line of buildsessionfactory in hibernate Util that it throws this exception. my hibernate util class is ok also. this is the error java.lang.NoSuchMethodError: javax.persistence.OneToMany.orphanRemoval()Z

推荐答案

删除 ejb3-persistance.jar 并将其从构建路径中删除解决了我的问题，它也可能对您有用.

Deleting ejb3-persistance.jar and removing it from build path solved my problem, it may work for you too.

另外不要忘记将 hibernate-jpa-2.0-api-1.0.0.Final.jar 添加到您的构建路径中.

Also don't forget to add hibernate-jpa-2.0-api-1.0.0.Final.jar to your build path.
