public class CustomNumberEditor extends PropertyEditorSupport
decode
/ valueOf
/ toString
methods.
This is not meant to be used as system PropertyEditor but rather as locale-specific number editor within custom controller code, parsing user-entered number strings into Number properties of beans and rendering them in the UI form.
In web MVC code, this editor will typically be registered with
binder.registerCustomEditor
calls.
