我之前有一个关于这个的问题，但是我得到了一些来自某人的帮助。那真是太好了。代码如下：

<body>
    <form action="dataExchange" method="POST">
        Date:           <input type="text" name="Date"><br>
        Name:           <input type="text" name="Name"><br>
        Address:        <input type="text" name="Address"><br>
        Allday Hours:   <input type="text" name="Allday_hours"><br>
        Day Hours:      <input type="text" name="Day_hours"><br>
        Day Minutes:    <input type="text" name="Day_minutes"><br>
        Km To Address:  <input type="text" name="Km_to_address"><br>
        Time To Address:<input type="text" name="Time_to_address"><br>
                        <input type="submit" value="submit">
    </form>
</body>

<%@ page language="java" contentType="text/html; charset=US-ASCII"
    pageEncoding="US-ASCII"%>

<body>
    <form action="../dataExchange" method="POST">
        Date:           <input type="text" name="Date"><br>
        Name:           <input type="text" name="Name"><br>
        Address:        <input type="text" name="Address"><br>
        Allday Hours:   <input type="text" name="Allday_hours"><br>
        Day Hours:      <input type="text" name="Day_hours"><br>
        Day Minutes:    <input type="text" name="Day_minutes"><br>
        Km To Address:  <input type="text" name="Km_to_address"><br>
        Time To Address:<input type="text" name="Time_to_address"><br>

所以，当我像这样设置值时，信息将正确地注册到数据库中

                    pst.setString(1, 1999-01-01);
        pst.setString(2, Mads);
        pst.setString(3, Skolevej);
        pst.setString(4, 23);
        pst.setString(5, 12);
        pst.setString(6, 49);
        pst.setString(7, 56);
        pst.setString(8,  32);

但是，当我使用html站点的表单并将以下信息放入时：

String Date = req.getParameter("Date");
        String Name = req.getParameter("Name");
        String Address = req.getParameter("Address");
        String Allday_hours = req.getParameter("Allday_hours");
        String Day_hours = req.getParameter("Day_hours");
        String Day_minutes = req.getParameter("Day_minutes");
        String Km_to_address = req.getParameter("Km_to_address");
        String Time_to_address = req.getParameter("Time_to_address");

我得到一个HTTP状态404错误。有人知道这是为什么吗？我的猜测是JSP和Servlet之间有问题

尝试在表单元素的action属性中添加一个前导斜杠，例如：

<form action="/dataExchange" method="POST">

而不是

<form action="dataExchange" method="POST">

正确的代码如下：

<body>
    <form action="dataExchange" method="POST">
        Date:           <input type="text" name="Date"><br>
        Name:           <input type="text" name="Name"><br>
        Address:        <input type="text" name="Address"><br>
        Allday Hours:   <input type="text" name="Allday_hours"><br>
        Day Hours:      <input type="text" name="Day_hours"><br>
        Day Minutes:    <input type="text" name="Day_minutes"><br>
        Km To Address:  <input type="text" name="Km_to_address"><br>
        Time To Address:<input type="text" name="Time_to_address"><br>
                        <input type="submit" value="submit">
    </form>
</body>

YYYYYeeeesss。现在它可以工作了：-它并没有和：一起使用，但若你们不建议这样做，我就不会想把它放在前面。太酷了。谢谢。我要修改密码，让其他人看到正确的
