this is better because if you use applications to hold non-proxied daos
you have to be very careful not to leave a reference to it anywhere. because
dependencies injected throgh @SpringBean are special proxies you dont have
to worry about it because the proxies can be safely serialized.
I do understand that. But isn't it very easy to avoid it? For example the
PersonClass would be something like this:
class PersonModel extends LoadableDetachableModel {
private final long id;
public PersonModel(long id) {
this.id=id;
}
private PersonDao getDao() {
return MyApplication.get().getPersonDao();
...
}
With this getter there is no temptation to save the DAO as a field.
