Form values to be NULL instead of empty strings in Spring MVC

I am using Spring MVC. I have a form on my page. When I do not enter any values to the form and submit it, it comes with empty strings "".

Is it possible to set null value instead of empty strings?

Thanks in advance for your help.

You have to use the @InitBinder annotation because in Spring MVC it always returns "" for the blank values in a form. You have to add this in your controller.

Example: 

@InitBinder    /* Converts empty strings into null when a form is submitted */
public void initBinder(WebDataBinder binder) {  
    binder.registerCustomEditor(String.class, new StringTrimmerEditor(true));  
}
