Question

I have this propery in my entity class:

@Column(name="avatar",nullable=false,length=1000)
String getAvatarData() {
    return new JSONObject(avatar.export()).toString();
}
void setAvatarData(String data) {
    avatar = Avatar.restore(new JSONObject(data).toMap());
}

Hibernate doesn’t handle it at all. At least, it’s not included in the schema it generates.

Answer 1

@Access(AccessType.PROPERTY)

on your entity. That’s JPA 2.0. For 1.0, use org.hibernate.AccessType:

@AccessType("property")

By the way, I would rather have a simple field with getters and setters, and annotate the field instead. Then, if you want custom transformations, add other methods, like getFooAsJSON
