Validation and binding in Spring3

[Yewint Ko]

Hi all
please , somebody show me the example of validation and error binding in spring3. I have the follwing @Controllers and I want to show errors message to user if the account validation failed.

This is Account Controller ..

   

  @Controller
@RequestMapping(value="/account/**")
public class AccountController {

  ///do some DI 

  @RequestMapping(value="/account/save")
  public String accountSave( @Valid Account account ){
    ///// do some saving logic  and return some path
  }
   
 /// other methods omitted
}
 

How can I enhance the above controller for validation and error binding .
