spring - What are the differences between Model, ModelMap, and ModelAndView?

What are the main differences between the following Spring Framework classes?

  • Model
  • ModelMap
  • ModelAndView

Using Model.put(String,Object) we can access the values in .jsp files, but ModelMap.addAttribute(String,Object) also did same thing. I do not understand the difference between these classes.

Model is an interface while ModelMap is a class.

ModelAndView is just a container for both a ModelMap and a view object. It allows a controller to return both as a single value.
