In spring mvc, headers = "x-requested-with:XMLHttpRequest" in request mapping not working?

Question

I have two methods, one is supposed to handle login request issued by JS, another takes care of login page.

 @RequestMapping(value = "/login", method = {RequestMethod.GET, RequestMethod.HEAD},
    headers = "x-requested-with:XMLHttpRequest")
    public @ResponseBody String login() {...}


 @RequestMapping(value = "/login", method = {RequestMethod.GET, RequestMethod.HEAD})
    public String getLoginPage() {......}

However, all the login requests seems to go to the getLoginPage method whether it has "x-requested-with:XMLHttpRequest" header or not. I doubled checked http headers, it contains correct head. So it seems Spring just ignores the login method.

I've been struggling with this for a while, any advice would be greatly appreciated, thanks!

Answer 1

headers uses = as a delimiter:

@RequestMapping(value = "/login", method = {RequestMethod.GET, RequestMethod.HEAD},     
    headers = "x-requested-with=XMLHttpRequest")
