Hi all,
I am sorry, but i cannot get it working. I have three tables with a PK beeing a single
attribute. And then I have another table, with three attributes each referencing the PK of
one table. And these three attributes are at the same time the PrimaryKey (PK)
SQL looks like this:
| CREATE TABLE ListedSections (
| SectionID SMALLINT NOT NULL,
| SectionName CHARACTER VARYING(50) NOT NULL,
| SectionDescription CHARACTER VARYING(150),
| DateAdded TIMESTAMP DEFAULT current_timestamp,
| ActiveUntil TIMESTAMP,
| CONSTRAINT PK_ListedSections PRIMARY KEY (SectionID)
| );
|
| CREATE TABLE ListedRights (
| RightID SMALLINT NOT NULL,
| RightName CHARACTER VARYING(50) NOT NULL,
| RightDescription CHARACTER VARYING(150),
| DateAdded TIMESTAMP DEFAULT current_timestamp,
| ActiveUntil TIMESTAMP,
| CONSTRAINT PK_ListedRights PRIMARY KEY (RightID)
| );
|
| CREATE TABLE ListedRoles (
| RoleID SMALLINT NOT NULL,
| RoleName CHARACTER VARYING(40) NOT NULL,
| RoleDescription CHARACTER VARYING(150),
| DateAdded TIMESTAMP DEFAULT current_timestamp,
| ActiveUntil TIMESTAMP,
| CONSTRAINT PK_ListedRoles PRIMARY KEY (RoleID)
| );
|
| CREATE TABLE RoleHasRights (
| RightID SMALLINT NOT NULL,
| RoleID SMALLINT NOT NULL,
| SectionID SMALLINT NOT NULL,
| CONSTRAINT PK_RoleHasRights PRIMARY KEY (RightID, RoleID, SectionID)
| );
|
| ALTER TABLE RoleHasRights ADD CONSTRAINT ListedRights_RoleHasRights
| FOREIGN KEY (RightID) REFERENCES ListedRights (RightID);
|
| ALTER TABLE RoleHasRights ADD CONSTRAINT ListedRoles_RoleHasRights
| FOREIGN KEY (RoleID) REFERENCES ListedRoles (RoleID);
|
| ALTER TABLE RoleHasRights ADD CONSTRAINT ListedSections_RoleHasRights
| FOREIGN KEY (SectionID) REFERENCES ListedSections (SectionID);
|
My Entities are looking like this:
| package myPackage;
|
| import java.io.Serializable;
| import java.sql.Timestamp;
| import java.util.Collection;
| import java.util.ArrayList;
|
| import javax.persistence.Entity;
| import javax.persistence.Id;
| import javax.persistence.JoinColumn;
| import javax.persistence.OneToMany;
| import javax.persistence.Table;
|
| @Entity
| @Table(name="listedroles", schema="public",
catalog="postgres")
| public class Role implements Serializable {
| private static final long serialVersionUID = 1L;
| private int roleid;
| private String roleName;
| private String roleDescription;
| private Timestamp dateadded;
| private Timestamp activeuntil;
| private Collection<RoleHasRights> roleHasRights = new
ArrayList<RoleHasRights>();
|
| //--------------------------------------------------------------------------
| @Id
| public int getRoleid() {
| return this.roleid;
| }
|
| //--------------------------------------------------------------------------
| public void setRoleid(int roleid) {
| this.roleid = roleid;
| }
|
| //--------------------------------------------------------------------------
| public String getRoleName() {
| return this.roleName;
| }
|
| //--------------------------------------------------------------------------
| public void setRoleName(String roleName) {
| this.roleName = roleName;
| }
|
| //--------------------------------------------------------------------------
| public String getRoleDescription() {
| return this.roleDescription;
| }
|
| //--------------------------------------------------------------------------
| public void setRoleDescription(String roleDescription) {
| this.roleDescription = roleDescription;
| }
|
| //--------------------------------------------------------------------------
| public Timestamp getDateadded() {
| return this.dateadded;
| }
|
| //--------------------------------------------------------------------------
| public void setDateadded(Timestamp dateadded) {
| this.dateadded = dateadded;
| }
|
| //--------------------------------------------------------------------------
| public Timestamp getActiveuntil() {
| return this.activeuntil;
| }
|
| //--------------------------------------------------------------------------
| public void setActiveuntil(Timestamp activeuntil) {
| this.activeuntil = activeuntil;
| }
|
| //--------------------------------------------------------------------------
| @OneToMany(mappedBy="roleHasRightsPK.roleid")
| @JoinColumn(name="roleHasRightsPK")
| public Collection<RoleHasRights> getRoleHasRights() {
| return this.roleHasRights;
| }
|
| //--------------------------------------------------------------------------
| public void setRoleHasRights(Collection<RoleHasRights> roleHasRights) {
| this.roleHasRights = roleHasRights;
| }
| }
|
Sections and Rights are nearly the same
And RoleHasRights:

|

| }
|
| //--------------------------------------------------------------------------

| @Override

| }
| RoleHasRightsPK other = (RoleHasRightsPK) o;
| return (this.roleid == other.roleid)

| }
|
| //----------------------------------------------------------------------
| @Override
| public int hashCode() {
| return ((int) (this.roleid ^ (this.roleid >>> 32)))
| ^ ((int) (this.rightid ^ (this.rightid >>> 32)))

| }
| }
| }

Can anybody help my getting this working? Thank you very much and kind regards,
