Spring MVC 3.0 Annotations - Conversation Forms - Beginner Questions

How do you do the following in Spring 3.0? (I foun开发者_JAVA百科d so many results, I'm not sure which is the right way)

What I want to know is how to do the following in the "best practice" standart Spring 3.0 Annotation way

• Multiple page form (How to use @SessionAttributes)
• Multiple submit buttons on a form (should I use @RequestMapping(params={"btn1"}...) ?)
• Automatic binding of form fields to beans (@InitBinder? must it use "Spring" forms?)

• Multiple page form -- have a look at Spring Web Flow
• Multiple submit buttons -- @RequestMapping(params={"btn1"}...) should do the job
• Automatic binding -- better to use Spring Conversion with Converters - (they are stateless in difference to Binders)
