| Hi, I want to achieve the composite key on an entity as follows but getting error. PFA for stack trace.
Values are inserting in system_user_table. When i gave the foreign-key reference in user table its not allowing me to save data.
Please help. Entity SystemUser
public class SystemUser implements Serializable {
private Long systemUserID;
private String spaceKey;
@Id
@GeneratedValue(generator = "SystemUserGenerator")
@GenericGenerator(name = "SystemUserGenerator", strategy = "org.hibernate.shards.id.ShardedTableHiLoGenerator")
@Column(name = "system_user_id")
public Long getSystemUserID() { return systemUserID; } @Id
@Column(name = "SPACE_KEY", insertable = false, updatable = false)
public String getSpaceKey() { return spaceKey; }
.......
.......
// hashcode and equals methods
}
Entity User
public class User implements Serializable {
private Long id;
private String spaceKey;
private SystemUser systemUser;
@Id
@GeneratedValue(generator = "UserGenerator")
@GenericGenerator(name = "UserGenerator", strategy = "org.hibernate.shards.id.ShardedTableHiLoGenerator")
@Column(name = "id")
public Long getId() { return id; }
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumns({@JoinColumn(name = "SYSTEMUSER_ID", referencedColumnName = "system_user_id", columnDefinition = "bigint default 0"), @JoinColumn(name = "SPACE_KEY", referencedColumnName = "SPACE_KEY", insertable = false, updatable = false)})
public SystemUser getSystemUser() { return systemUser; }
@Id
@Column(name = "SPACE_KEY", insertable = false, updatable = false)
public String getSpaceKey() { return spaceKey; } .......
.......
// hashcode and equals methods
} |
