Spring Security CSRF Token not working with AJAX call & form submit in same JSP

Question

I am trying to implement spring security (ver 3.2.3) CSRF token in my project by referring below links

http://docs.spring.io/autorepo/docs/spring-security/4.0.0.CI-

Answer 1

I hope this below answer helps. Make these changes

var csrfParameter = $("meta[name='_csrf_parameter']").attr("content");
var csrfToken = $("meta[name='_csrf']").attr("content"); 
var csrfHeader = $("meta[name='_csrf_header']").attr("content");  // THIS WAS ADDED

and after

data[csrfParameter] = csrfToken;
data["institutionId"] = option;
headers[csrfHeader] = csrfToken;    // THIS WAS ADDED

finally change in the ajax call:

url: './getMerchantByInstitution.htm',
headers: headers,    // THIS WAS ADDED
data: data,//"institutionId=" + option,
dataType:'json',

Let me know if this works.
