I am not a spring expert/user so i am a bit curious when is it all injected?
for example if i do this:
setResponsePage(new UserPage(user));
and that userpage has some spring beans that also must be instantiated?
And then that userpage is serialized how do you inject those beans again?
Did you overwrite the readObject() ??

As Stefan explained I guess he is doing a little AOP to inject dependencies:
something like:
after(UserPage page) returning(): call(UserPage.new(..)) && target(page) {
// wire dependencies here
}
Also he said he solved the serialization problem. I assume that the above piece of advice may work
the same way against a deserialization.
I haven't seen his code yet (I am waiting for it), but this is what I am imagining from watching the
thread.

Yup. But I don't see how this would work. How would you specify this
one for example:
<bean name="blueImageRenderer" class="ImageRendererImpl">
<property name="color" value="blue"/>
</bean>
<bean name="yellowImageRenderer" class="ImageRendererImpl">
<property name="color" value="yellow"/>
</bean>
public class FooPage extends WebPage
{
@SpringBeanReference("blueImageRenderer")
transient private ImageRenderer blueImageRenderer;
public setBlueImageRenderer(ImageRenderer blueImageRenderer) {
this. blueImageRenderer = blueImageRenderer;
}
@SpringBeanReference("yellowImageRenderer")
transient private ImageRenderer yellowImageRenderer;
public setYellowImageRenderer(ImageRenderer yellowImageRenderer) {
this. yellowImageRenderer = yellowImageRenderer;
}
}
I know it is a silly example :-)
I'm not sure how you would do this on the class level. The annotation
there then would have to get both bean name and property names in an
array of pair. Makes no sense to me.
