提交表单数据后如何重新加载JSP页面

问题描述：

只是想知道如何在表单中提交数据后刷新jsp页面.

Just wondering how to refresh the jsp page after submitting data in the form.

if (request.getParameter("key") != null){
        if (request.getParameter("value") != null){
            Cookie cookie = new Cookie(request.getParameter("key"), request.getParameter("value"));
            response.addCookie(cookie);
        }
    }

我应该在response.addCookie之后添加一些内容吗?

should I add something following the response.addCookie ?

答

假设您从表单提交到SubmitServlet，然后使用RequestDispatcher或response.sendRedirect

suppose you submit to SubmitServlet from the form, then redict to the same JSP from it using RequestDispatcher or response.sendRedirect
