I have defined a custom type and convertor for that. The convertor is
actually managed by Spring and populated with a DAO and the
convertor's factory returns the Spring-managed instance instead of
creating a new one.
The convertor itself is spring manager or just the dao it holds?
Both.
Do I get it right that you need to implement a separate:
- dao
- convertor
- convertor builder
for every domain object in your model?
Not really. I do it only for those types that are reused across many
forms and therefore warrant defining a datatype and convertor. At the
moment, we have developed datatypes for a bunch of "geographical"
objects like Town, Province, Country, that are used in all the forms
where you have to input an address. And we have a single "GeoDAO" class
for all entities of this kind.
In general, I would do this for every "datatype" that is implemented as
a look-up-table (key => value) in the database and is reused in more
than a couple of forms, or across more than one different project.
