Using the setAllowedFields() method in Spring

Question

I\'m using Spring 3.2.0. I have registered a few custom property editors for some basic needs as follows.

import editors.DateTimeEditor;
import edito         


        

Answer 1

A solution to use binder with DTO (companydata in example) in case most of the form input values should be converted to null if empty, but there is a need to add few exceptions (setDisallowedFields didn't work for me).

@InitBinder()
public void initBinder(WebDataBinder binder) {
    binder.registerCustomEditor(String.class, new StringTrimmerEditor(true));
}

@InitBinder
protected void initBinder(HttpServletRequest request, ServletRequestDataBinder binder) {
    binder.registerCustomEditor(String.class, "companydata.companyName", new StringTrimmerEditor(false));
    binder.registerCustomEditor(String.class, "companydata.companyNumber", new StringTrimmerEditor(false));
}
