JPA TABLE_PER_CLASS繼承：創建抽象實體表

我創建了3個實體類，名爲NodeBase,NodeDocument和NodeFolder。JPA TABLE_PER_CLASS繼承：創建抽象實體表

使用表每類繼承stategy和如表每類繼承定義的一個表被定義爲繼承層次結構中的每個具體的類，在這種情況下NodeBase是抽象的實體但該實體的表中創建命名NODEBASE。

Entity relationship diagram

@Entity 
@Inheritance(strategy=InheritanceType.TABLE_PER_CLASS) 
public abstract class NodeBase implements Serializable { 

    @Column(name="NBS_UUID") 
    @Id 
    @GeneratedValue(strategy=GenerationType.AUTO) 
    private Long uuid; 

    @Column(name="NBS_NAME") 
    @Basic 
    private String name; 

    @ManyToOne(targetEntity = NodeFolder.class) 
    private NodeFolder parent; 

} 


@Entity 
@Table(name="SDM_NODE_DOCUMENT") 
public class NodeDocument extends NodeBase implements Serializable { 

    @Column(name="NDC_MIMETYPE") 
    @Basic 
    private String mimeType; 

} 

@Entity 
@Table(name="SDM_NODE_FOLDER") 
public class NodeFolder extends NodeBase implements Serializable { 

    @OneToMany(targetEntity = NodeBase.class,mappedBy = "parent") 
    private Collection<NodeBase> children; 
}

如何創建實體類，以僅兩個表應創建一個名爲SDM_NODE_DOCUMENT和SDM_NODE_FOLDER的方法嗎？
