1. Variable request is declared, but is not initialized. No wonder you get a NullPointerException.

2. Look at documentation to access different request related data.

After you read that, and are sure you want to tie your code to native Servlet API, try this:

@Controller
class MyController {

    @RequestMapping
    public void handleMe(HttpServletRequest request) {
        String path = request.getContextPath();
    }
}
