There are two problems with creating a spring web page factory:
1) pages get serialized and you don't want to serialize all the enjected
deps along with it, so you need a mechanism that reinjects the dependencies
whenever a page is activated - or whenever a page references another page
that has been serialized. This can be difficult to achieve transparently and
can get expensive.
2) to use the page factory your pages can only have the default or
PageParameter constructors. This prevents you from doing things like
setResponsePage(new EditUserPage(userId));
I still think the webapplication subclass is the best place for injecting
dependencies. In your base page class you can create helpers that retrieve
the deps from the webapp subclass:
Ie
Class BasePage extends WebPage() {
UserService getUserService() {
return
((MyWebAppSubclass())getApplication()).getUserService();
}
}
