#ManyToMany relation with composite key and extra column, nested column in intermediate table - jpa

Question

this is my current situation :
I have a diagram like this. In the intermediate tables I have 1 more extra column. The problem here is in the table "Period_Area_CC", the column "Area_CompNo" is referenced by 2 columns ("CompNo" from table "CC" and "Area_CompNo" from tablle "Period_Area")
And here is my mapping
public class Area extends BaseEntity {
#EmbeddedId
private AreaId id;
#OneToMany(mappedBy = "area", cascade = CascadeType.ALL, orphanRemoval = true)
private List<AreaPeriod> areaPeriods;
}
public class AreaPeriod implements Serializable {
#Id
#Column(name = "periodAssignmentID")
private Long periodID;
#Id
#Column(name = "areaID")
private Long areaID;
#Id
#Column(name = "companyNo")
private Long companyNo;
private Long parentId;
#Column(name = "hierarchyPath")
private String hierarchyPath;
#ManyToOne
#JoinColumns({#JoinColumn(name = "areaID", referencedColumnName = "areaID", updatable = false, insertable = false),
#JoinColumn(name = "companyNo", referencedColumnName = "companyNo", updatable = false, insertable = false)})
private Area area;
#ManyToOne
#JoinColumns({#JoinColumn(name = "periodAssignmentID", referencedColumnName = "periodAssignmentID", updatable = false, insertable = false)})
private VirtualAreaPeriodDefinition period;
#OneToMany(mappedBy = "parent", cascade = CascadeType.ALL)
private Set<AreaPeriod> children;
#ManyToOne
#JoinColumns({#JoinColumn(name = "periodAssignmentID", referencedColumnName = "periodAssignmentID", insertable = false, updatable = false),
#JoinColumn(name = "parentId", referencedColumnName = "areaID", insertable = false, updatable = false),
#JoinColumn(name = "companyNo", referencedColumnName = "companyNo", insertable = false, updatable = false)})
private AreaPeriod parent;
#OneToMany(mappedBy = "areaPeriod", cascade = CascadeType.ALL, orphanRemoval = true)
private List<CostCenterAreaPeriod> costCenterAreaPeriods;
}
public class CostCenterAreaPeriod implements Serializable {
#Id
#Column(name = "companyNo")
private Long companyNo;
#Id
#Column(name = "periodAssignmentID")
private Long periodId;
#Id
#Column(name = "areaID")
private Long areaId;
#Id
#Column(name = "CostCenterEnum")
private Long costCenterEnum;
private String hierarchyPath;
#ManyToOne
#JoinColumns({#JoinColumn(name = "areaID", referencedColumnName = "areaID", updatable = false, insertable = false),
#JoinColumn(name = "companyNo", referencedColumnName = "companyNo", updatable = false, insertable = false),
#JoinColumn(name = "periodAssignmentID", referencedColumnName = "periodAssignmentID", updatable = false, insertable = false)})
private AreaPeriod areaPeriod;
#ManyToOne
#JoinColumns({#JoinColumn(name = "CompanyNo", referencedColumnName = "companyNo", updatable = false, insertable = false),
#JoinColumn(name = "CostCenterEnum", referencedColumnName = "CostCenterEnum", updatable = false, insertable = false)})
private CostCenter costCenter;
}
public class CostCenter extends BaseEntity {
private static final long serialVersionUID = -2290076530189347245L;
#EmbeddedId
private CXCostCenterPK id;
#OneToMany(mappedBy = "costCenter", cascade = CascadeType.ALL, orphanRemoval = true)
private List<CostCenterAreaPeriod> costCenterAreaPeriods;
}
Because I have marked the relation with insertable and updateable false so I have to insert manually.
So is there any better solution, so I just need to map the relation on the entity, then JPA will handle the insert/update/delete funtion?
Updated :
public class CXCostCenterPK implements Serializable {
private static final long serialVersionUID = 658550094878047277L;
#Column(name = "CompanyNo")
private Long companyNo;
#Column(name = "CostCenterEnum")
private Long costCenterEnum;
}
public class AreaId implements Serializable {
#Column(name = "companyNo", length = 5, nullable = false)
private Long companyNo;
#Column(name = "areaID", length = 11, nullable = false)
private Long areaEnum;
}
