RequestMapping annotation is used to map web requests onto specific handler classes and/or handler methods. @RequestMapping can be applied to the controller class as well as methods.

@NotNull(message = "This is a required field.") @Size(min=1, message = "This is a required field.") @Size with min=1 ensures that there is at least one character in the field to pass the validation test, thus an empty String ?? will fail the validation.
