Deeps,
I am reading
Spring in Action by Craig Walls but i dont remember which version of spring it teaches

. I think spring 2.0 version
This book is good and it is more like a text book i would suggest you to buy Spring Live and it explains concepts with examples and it uses lot of screen shots also(i like graphical way of learning than reading lengthy text).
This is my opinion any way you can read through the sample chapters of both books available online before buying them...I dont know about other books.
