我有一个站点,其URL以"http://"开头,但这给了我一个例外消息 - 不支持的协议:https.该站点是否可能使用HTTPS协议,其URL仍以"http://"开头,而不是"https://".

public ActionForward executeAction(ActionMapping mapping, ActionForm form,
              HttpServletRequest request, HttpServletResponse response)
      throws Exception {

    ActionForward forward = mapping.findForward(Constants.SUCCESS);
    String link = "http://abc.fgh.jkl.mno";
    URL thisURL;
    HttpURLConnection conn = null;
    try {
        thisURL = new URL(link);
        conn = (HttpURLConnection) thisURL.openConnection();
        System.out.println(conn.getResponseCode());
        System.out.println(conn.getResponseMessage());
        } catch (Exception ex) {
        ex.printStackTrace();
    }
    return forward;
}
