Migrating from Spring 3 to Spring 2, what do you need to remember?

Question

I was told that I need to develop a Spring 2 application (I don’t know why they do not want to use a Spring 3 application, since they use Java 5). The problem is that all my experience is related to Spring 3.

I know there is a reference guide, but I find it much easier if you move forward rather than backward.

So I was wondering what are the main differences between the two. I expect that in xmls you will work more with settings.

In Spring 3, I mostly use binding @RequestMapping, @ModelMapping, path to jsp, automatic type conversion from String to date, hibernate-validator, ...

Any pointers would be appreciated.
