[FIXED] Disable Spring Security for OPTIONS Http Method

Issue

Is it possible to disable Spring Security for a type of HTTP Method?

We have a Spring REST application with services that require Authorization token to be attached in the header of http request. I am writing a JS client for it and using JQuery to send the GET/POST requests. The application is CORS enabled with this filter code.

doFilter(....) {

  HttpServletResponse httpResp = (HttpServletResponse) response;
  httpResp.setHeader("Access-Control-Allow-Origin", "*");
  httpResp.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
  httpResp.setHeader("Access-Control-Max-Age", "3600");
  Enumeration<String> headersEnum = ((HttpServletRequest) request).getHeaders("Access-Control-Request-Headers");
  StringBuilder headers = new StringBuilder();
  String delim = "";
  while (headersEnum.hasMoreElements()) {
    headers.append(delim).append(headersEnum.nextElement());
    delim = ", ";
  }
  httpResp.setHeader("Access-Control-Allow-Headers", headers.toString());
}

But when JQuery sends in the OPTIONS request for CORS, the server responds with Authorization Failed token. Clearly the OPTIONS request, lacks Authorization token. So is it possible to let the OPTIONS escape the Security Layer from the Spring Security Configuration?

Solution

Have you tried this

You can use multiple elements to define different access requirements for different sets of URLs, but they will be evaluated in the order listed and the first match will be used. So you must put the most specific matches at the top. You can also add a method attribute to limit the match to a particular HTTP method (GET, POST, PUT etc.).

<http auto-config="true">
    <intercept-url pattern="/client/edit" access="isAuthenticated" method="GET" />
    <intercept-url pattern="/client/edit" access="hasRole('EDITOR')" method="POST" />
</http>

Above means you need to select the url pattern to intercept and what methods you want
