我有以下實體，具有多對多的關係。使用@Audited在添加到子類但不適用於所有實體時工作正常 面向編譯錯誤（例外）Hibernate Envers審覈多對多複合主鍵不適用於父類
Employee類
@Entity
@Table(name = EMPLOYEE)
@Audited
public class Employee implements java.io.Serializable {
@EmbeddedId
@AttributeOverrides({
@AttributeOverride(name = "Id", column = @Column(name = "ID", nullable = false, length = 50)),
@AttributeOverride(name = "department", column = @Column(name = "DEPARTMENT", nullable = false, length = 10)) })
private DepartmentId id;
@Column(name = "NAME", length = 50)
private String name;
@OneToMany(mappedBy = "key.emp", cascade = { CascadeType.ALL }, fetch = FetchType.EAGER,orphanRemoval=true)
private Set<EmpAddress> empAddMap = new HashSet<EmpAddress>();
}
複合主鍵類爲僱員
@Component
@Embeddable
@Audited
public class DepartmentId implements java.io.Serializable {
@Column(name = "ID", nullable = false, length = 50)
private String id;
@Column(name = "DEPARTMENT", nullable = false, length = 10)
private String department;
}
地址類
@Entity
@Table(name = "ADDRESS")
@Audited
public class Address implements java.io.Serializable {
private static final long serialVersionUID = 5070283391974818811L;
@Id
@Column(name = "CITY", unique = true, nullable = false, length = 50)
private String city
@Column(name = "CONTACT")
private String contact;
@OneToMany(mappedBy = "key.address", cascade = { CascadeType.ALL }, fetch = FetchType.EAGER)
private Set<EmpAddress> empAddMap = new HashSet<EmpAddress>();
}
映射類許多與員工一對多的關係和地址映射實體
@Entity
@Table(name = "EMPLOYEE_ADDRESS", catalog = "LRR")
@AssociationOverrides({
@AssociationOverride(name = "key.emp", joinColumns = { @JoinColumn(name = "ID"),
@JoinColumn(name = "DEPARTMENT") }),
@AssociationOverride(name = "key.address", joinColumns = @JoinColumn(name = "CITY")) })
@Audited
public class EmpAddress {
@EmbeddedId
private EmpAddId key = new EmpAddId();
@Column(name = "STATUS_ID")
private String statusId;
}
複合主鍵類
@Embeddable
public class EmpAddId implements Serializable {
@ManyToOne(cascade = CascadeType.ALL)
private Employee emp;
@ManyToOne(cascade = CascadeType.ALL)
private Address address;
