I want my controllers to parse dates in RequestParams and PathVariables according to a standard format.

Is it possible to set an application-wide @DateTimeFormat without annotating every @RequestParam individually?

You can do it at the controller level. Add @initBinder in your controller and it will format the date according to the given formatter.

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

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

Not part of the original question but, is there a way to override this for individual request params? It seems that DateTimeFormat gets ignored when I use InitBinder.
I do not see a way to do that. There might be a way but i am not aware of that.

It might be possible by Spring AOP but how would you tell your code if you have different keys for date in request. but check following link for more derails:
