Dear All ..
i have four fieild that exist in all tables ..i want to use
@MapperSuperClass .I test and I found that when there is a extended class
that have IdClass PCEnhancer cuase null pointer exception. I use OpenJPA.1.2
in other cases there is no problem..... in the following class in
ValuableItemDA there is no problem and everything work well.. but in
SituationDA that have a IdClass it cause null pointer excpetion. in
PCEnhancer..i think i should add some extera annotation?but i dont know how
solve the problem...
@MappedSuperclass
public abstract class CashBaseEntity extends BaseEntity{
@Column(name="TRCCRUI")
private String createUser;
@Column(name="TRCCRTS")
private Date createTime;
@Column(name="TRCLUUID")
private String updateUser;
@Column(name="TRCLUTS")
private Date updateTime;
@Version
@Column(name="TRCVER")
private int version;
//getter setter ....removed ..for short post
}
@Entity
@Table ( name = "cc2SITUATION")
@IdClass(SituationDA.SituationId.class)
public class SituationDA extends CashBaseEntity{
@Id
@Column(name="C2008SRL")
private String CashBoxPeriodSerial;
@Id
@Column(name="C2012TYPE")
private short Type;
public static class SituationId implements Serializable{
private static final long serialVersionUID = 1L;
public String CashBoxPeriodSerial;
public short Type;
public SituationId(){
}
public boolean equals(Object other){
if (other instanceof SituationId) {
final SituationId otherId = (SituationId)other;
return (
otherId.CashBoxPeriodSerial.equals(this.CashBoxPeriodSerial) &&
otherId.Type == this.Type );
}
return false;
}
public int hashCode() {
return super.hashCode();
}
}
//getter setter removed for short post..
}
@Entity
@Table (name = "CF2VLUITEM")
public class ValuableItemDA extends CashBaseEntity{
@Id
@Column(name="C2001COD")
private short Code;
//getter setter removed for short post..
}
