7:45 a.m.
Let's imagine I have several (say 10) classes that I'd like
to make
persistent. The classes form completed domain model.
I decided to use hibernate and JPA annotations, I have lets say JBDS
1.1.0 or JBossTools 2.1.0 installed.
Question is what I should do to make my model persistent? It there
anything that helps me to do it?
Not that I'm aware, the thing that get closest is maybe Dali JPA which has
as JPA View where you can click to make something an entity.
I'm not sure it does anything else than add @Entity to the class.
Now I see only way. I have to go through all classes and add
annotations
for class and for fields.
Having a "Make this class and its related classes mapped via JPA" would be
an interesting Refactoring to implement.
Should basically just work like this:
makePersistent(ITypeRoot clazz, Set processed) {
add @Entity
Find most likely id property and add @Id
processed.add(selectedClass);
associations = getAssociatedClasses(selectedClass);
foreach class in associations {
if(!processed.contains(class)) {
makePersistent(class, processed);
}
}
}
There then might be some exceptional cases like handling version properties, temporal
values and
non-JPA supported mappings which Hibernate would be able to understand/map.

Did I miss something?
Thanks
