推荐答案

有一个简单的解决方法，可以直接操作HttpServletRequest，使用getParameter()方法查看所有版本的参数.

There is a simple workaround.You can operate directly on the HttpServletRequest and use method getParameter() and check all versions of parameter.

public String welcome(HttpServletRequest request, ModelMap model){
   String orgID = extractOrgId(request);
   //rest of your code
}

private String extractOrgId(HttpServletRequest request){
   if(request.getParameter("orgId") != null){
       return request.getParameter("orgId");
   }
   // and so on
}
