Overriding Annotations in subclasses

Hi all,

I have an abstract superclass which has 2 fields:name and description. I use this superclass throughout my application by extending it as needed. My question is, in some of my subclasses, I want to add an annotation or change an annotation:

superclass

Code:

@Column(nullable = false)
public String getName()
{return(name);}

subclass

Code:

@RoleName
@Column(nullable = false, unique = true)
public String getName()
{return(name);}

Is it possible to override the method like that? I am getting this error.

Caused by: org.hibernate.MappingException: Duplicate property mapping of name found in com.walterjwhite.seamCore.model.security.Role

I would like to avoid any sorts of duplication when possible.

Thanks,
Walter

I think if you specify your super class as a @MappedSuperclass then it may work.

I've never personally done it but @AttributeOverride looks like what you might want.

Hi,

Thanks for your suggestion; however, upon looking at the JavaDoc, AttributeOverride only appears to override the column mapping and not the annotations on the superclass.

I simply want to only see the annotations the subclass has on the overridden method.
