How can I implement a redirect-after-post form with Spring's AnnotationMethodHandlerAdapter?

Question

I would like to write a @RequestMapping style form controller that redirects after a validation error and round-trips the values and error messages into the GET requested form (the Spring docs always just show the view being rendered in directly in response to the POST). Essentially, I think this comes down to putting the BindingResult into the session briefly and then placing it back in the model before the form is rendered.

I can't believe that I am the only person that wants to do this, but I can't find a way that doesn't involve duplicating the whole AnnotationMethodHandlerAdapter. Am I missing an easy solution?

Answer 1

You have two options:

• put the messages and model in the session
• use spring webflow's conversations

(I didn't get the duplication part)
