Question

我想从jsp页面向servlet传递两个值。 1-结果集值，2-获取参数值。

它应该在jsp页面中看起来像这样：

SCcalculator.getValue(rs.getString("value1"),request.getParameter("value1"));

在servlet端如何在SCcalculator包中接收和操作这些数据？有什么建议吗？

Answer 1

在servlet类中使用：

public void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException{
        String s = request.getParameter("value1");
        String s1 = request.getParameter("value");
}

在JSP中

不要这样做，而是：

<form action="name" method="post"> //here action=name is name of your servlet class name
    <input type="text" name="value">
    <input type="text" name="value1">
    <input type="submit" value="Send">       
</form>

Answer 2

考虑这个例子

<html>
<head>
<title>Demo application</title></head>
<body>

<form id = "form1" method = "GET" action = "../Sample Application">
link1 : <input type = "text" id = "nRequests" name = "nRequests" />         
<input type = "submit" name = "submit" id = "submit"/>

</form></body></html>

现在servlet将如何接受请求

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    nRequests = request.getParameter("nRequests");

通过这种方式，您可以将HTML页面中的值传递给servlet。

将GET参数和结果集传递给Java中的servlet
