Hello
i am wondering how i would be able to annotate an interface
@Entity
@Table(name = "FOLDER_TABLE")
public class Folder implements Serializable, Hierarchy {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "folder_id", updatable = false, nullable = false)
private int fId;
@Column(name = "folder_name")
private String folderName;
@OneToMany(cascade = CascadeType.ALL)
@JoinTable(name = "FOLDER_JOIN_FILE_INFORMATION_TABLE", joinColumns =
{ @JoinColumn(name = "folder_id") }, inverseJoinColumns =
{ @JoinColumn(name = "file_information_id") })
private List< Hierarchy > fileInformation = new ArrayList< Hierarchy >();
above and below are 2 classes that implement an interface called Hierarchy, the folder class has a list of Hierarchyies being a folder or a fileinformation class
@Entity
@Table(name = "FILE_INFORMATION_TABLE")
public class FileInformation implements Serializable, Hierarchy {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "file_information_id", updatable = false, nullable = false)
private int ieId;
@Column (name = "location")
private String location;
i have serached the web for someway to annotate or a workaround but i cannot map the interface which is simply this
public interface Hierarchy {
}
i get a mapping exeception on the List of hierarchyies with a folder but i dont know how to
map the class correctly
