Question

我编写了将用户添加到数据库的代码。我重新加载服务器时代码工作。但是，当我刷新页面时，我希望代码能够再次执行，但事实并非如此。以下是代码：

<%@page import="java.sql.*"%>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
    <head> 
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> 
        <title>Home page</title> 
        <script language="javascript" type="text/javascript">

</script>

    </head> 
    <body> 

        <jsp:useBean id="dataFactory" scope="session"     class="classes.Functions"/>     
       <%
         response.setHeader("Cache-Control","no-cache");

         out.print(dataFactory.getStatus());
         out.print(dataFactory.getError());

       %>

        <form style="text-align:center" name="loginform" action="index.jsp" method="POST">
            <img src="banner-02.jpg" width="700" height="150" alt="banner-02"/>
            <table>
                    <tr>
                         <td>User Name: </td>
                         <td><input type="text" name="UserName" value="" size="40" /></td>
                    </tr>
                    <tr>
                         <td>Password: </td>
                         <td><input type="text" name="Password" value="" size="40" /></td>
                    </tr>
             </table>
             <input type="reset" value="Clear" name="reset" /><input type="submit" value="Submit" name="submit" />
        </form>
    </body>

JSP代码不会在我刷新页面的地方执行
