Spring Security - All JQuery Ajax post requests return 404

All my $.ajax, both POST and GET were working fine, but as soon as I integrated Spring security 3.2.6 into my project the POST ajax requests stopped working without loggin any issues.

http://localhost:8080/ADMIN/workflow/sample-ajax

Could it be something to with spring security ?
