I want to get a common getUser static method so that I don"t have to manually convert token to user in every controller

public class UserUtil {
    @Autowired
    private static HttpServletRequest request;

    @Autowired
    private static HttpServletResponse response;

    public static User getUser() {
        return null;
    }

    public static String getUserName() {
        System.out.println(request);
        System.out.println(response);
        String cookieToken =CookieUtils.getCookie(request,"token");
        System.out.println("cookieToken:" + cookieToken);

        String headerToken = request.getHeader("token");
        System.out.println("headerToken:" + headerToken);
        return headerToken;
    }
}

but this doesn"t get the request object, so what should I do?
