我有休眠一個非常巨大的問題。休眠Inheritance.TABLE_PER_CLASS戰略
我的產業戰略，完美的作品下的EclipseLink作爲JPA提供者，無論是在GlassFish和JBoss應用服務器，但是當我切換到休眠狀態，一切都heywire。
我已經在這裏讀的幾個職位，但沒有解決我的問題。
以下是堆棧跟蹤。

我已經確定沒有子類定義了另一個@Id列（在任何情況下，NetBeans將始終標誌我這個錯誤）
這是一組遺傳的，我有：
@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
@PartialSecurity
public abstract class DataVerification extends SecureEntity implements Serializable {
private static final long serialVersionUID = IdGenerator.serialVersionUID(DataVerification.class);
@Id
private Long verificationId = IdGenerator.generateId();
@Column(length = 50, nullable = false)
private String verificationCode;
private String verifiedId;
private boolean verified;
@Temporal(javax.persistence.TemporalType.TIMESTAMP)
private Calendar verificationDate;
private DataVerificationType dataVerificationType;
private VerificationMethod verificationMethod;
@OneToOne
private Account verifiedBy;
@OneToOne
private Account approvedBy;
/**
*
* @author marembo
*/
@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
public class OnlineDataVerification extends DataVerification implements Serializable {
@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
@Ignore
private List<UploadFile> verificationFiles;
/**
*
* @author marembo
*/
@Entity
public class IncomeDataVerification extends OnlineDataVerification implements Serializable {
private static final long serialVersionUID = IdGenerator.serialVersionUID(IncomeDataVerification.class);
private IncomeSource incomeSource;
private String occupation;
/**
*
* @author marembo
*/
@Entity
public class AgentDataVerification extends OnlineDataVerification implements Serializable {
@Column(length = 2048, nullable = false)
private String comment;
private String verificationTransaction = IdGenerator.generateStringId();
謝謝
你能不能把基類和子類？ –
我有幾個繼承，就像我跟一個非常龐大的工程工作，但我張貼他們幾個 – maress
的這個異常通常是由重複@Id引起的，但你說你確信有沒有任何。 –
