If you are using Spring MVC as your application and Thymeleaf as your view engine please check out this section on dynamic forms and working with them:

http://www.thymeleaf.org/doc/tutorials/2.1/thymeleafspring.html#dynamic-fields

Essentially what you want to do is have an object that would have a Map as a variable within it, which would then bind all your inputs against when it hits the controller.

e.g.

public class MyObject {
    Map<String, Integer> myMap;

// getters and setters
}
