Question

What is the purpose and usage of @ModelAttribute in Spring MVC?

Answer 1

This is used for data binding purposes in Spring MVC. Let you have a jsp having a form element in it e.g

on JSP

(Spring Form method, Simple form element can also be used)

On Controller Side

@RequestMapping(value = "/test-example", method = RequestMethod.POST)
public ModelAndView testExample(@ModelAttribute("testModelAttribute") TestModel testModel, Map map,...) {

}

Now when you will submit the form the form fields values will be available to you.
