Spring: @ModelAttribute VS @RequestBody

Question

Please correct me if I am wrong. Both can be used for Data Binding.

The question is when to use @ModelAttribute?

@RequestMapping(val         


        

Answer 1

I find that @RequestBody (also annotating a class as @RestController) is better for AJAX requests where you have complete control over the contents of the request being issued and the contents are sent as either XML or JSON (because of Jackson). This allows the contents to easily create a model object. Conversely, @ModelAttribute seems to be better suited to forms where there is a "command" object backing a form (which may not necessarily be a model object).
