Annotation @DateTimeFormat needs a parameter to specify if you want to acept null or blank values to avoid exceptions when a date field is not mandatory [SPR-8669]

Angel opened SPR-8669 and commented

This enhancement would make the following addition to my controller completely unnecessary:

    @InitBinder
    public void initBinder(WebDataBinder binder) {
        SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
        dateFormat.setLenient(false);

        // true passed to CustomDateEditor constructor means convert empty String to null
        binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));
    }

Absolutely.

To avoid the empty String with dates problem I've ended up having register a separate custom editor for every date and time field in my entity.
This is clearly a maintenance nightmare.

We need to be able to set the leniency on the format.
