RequestParam value in spring MVC to be case insensitive

Question

Am sending data from JSP to controller using query string.

My controller is annotation driven.

The value of the the request parameter should be case-insensit

Answer 1

The simplest way I found was to change the controller method to take a Map with a single key value pair as a parameter and then convert the key to lowercase.

public String welcome(@RequestParam(required = true) Map params, ModelMap model) {
   String caseInsensitiveOrgId = params.keySet().toArray()[0].toString().toLowerCase();
   String OrgValue = params.values().toArray()[0];
   // Do whatever you want here
}
