Hardy Ferentschik updated METAGEN-76:
-------------------------------------
Description:
I got a class composite id class for a table with @Embeddable.
It has two properties, and the equals and the hashCode methods.
When hibernate-jpamodelgen 1.1.1.Final generates the metaclasses, I got a SingularAttribute with the name "hashCode" generated. But hashCode is not a property in the entity.
entity:
{code}
/** by hbm2java */
@Embeddable
public class MyTableId implements java.io.Serializable {
private String id;
private Integer memberId;
public MyTableId() {
}
public MyTableId(String id, Integer memberId) {
this.id = id;
this.memberId = memberId;
}
@Column(name="id")
public String getId() {
return this.id;
}
public void setId(String id) {
this.id = id;
}
@Column(name="member_id")
public Integer getMemberId() {
return this.memberId;
}
public void setMemberId(Integer memberId) {
this.memberId = memberId;
}
public boolean equals(Object other) {
if ( (this == other ) ) return true;
if ( (other == null ) ) return false;
if ( !(other instanceof MyTableId) ) return false;
MyTableId castOther = ( MyTableId ) other;
return ( (this.getId()==castOther.getId()) || ( this.getId()!=null && castOther.getId()!=null && this.getId().equals(castOther.getId()) ) )
&& ( (this.getMemberId()==castOther.getMemberId()) || ( this.getMemberId()!=null && castOther.getMemberId()!=null && this.getMemberId().equals(castOther.get
MemberId()) ) );
}
public int hashCode() {
int result = 17;
result = 37 * result + ( getId() == null ? 0 : this.getId().hashCode() );
result = 37 * result + ( getMemberId() == null ? 0 : this.getMemberId().hashCode() );
return result;
}
}
{code}
metaclass:
{code}
@StaticMetamodel(MyTableId.class)
public abstract class MyTableId_ {
public static volatile SingularAttribute<MyTableId, String> id;
public static volatile SingularAttribute<MyTableId, Integer> hashCode;
public static volatile SingularAttribute<MyTableId, Integer> memberId;
}
{code}
