title: How do I route my login controller
body: <p>I am using a homegrown (developers no longer around) web framework that has built in Spring security.</p>
  
  <p>There is a LoginController that every request is redirected to until the user logs in.</p>
  
  <p>The LoginController is mapped to use the context URL, e.g. my-company/login.do</p>
  
  <pre><code>public class LoginController {
  public LoginController() {
  }
  
  @RequestMapping(
      value = {"/login.do"},
      method = {RequestMethod.GET}
  )
  public String showLogin() {
      return "login";
  }
  </code></pre>
  
  <p>For my application, I need to change that mapping to my-company/<strong>admin</strong>/login.do</p>
  
  <p>The LoginController is coming in from a Maven dependency, so I CANNOT MODIFY that class</p>
  
  <p>Is there any way to modify the existing LoginController to route to the extended url?</p>
