jsp请求转发小例子(转载)

在服务器端对客户端请求时行转发对其它的对象,如果jsp网页或Servlet

用三个 jsp网页来演示转发:

forword1.jsp, 用来提交表单, 将表单内容提交给 forwrod2.jsp, forward1.jsp代码如下:

<%@page contentType="text/html" pageEncoding="UTF-8"%>

<!DOCTYPE html>

<html>

    <head>

        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

        <title>Forward1</title>

    </head>

    <body>

        <h1>Forward1</h1>

        <form action="forward2.jsp">

            姓名: <input type="text" name="username"/>

            <input type="submit" name="submit" value="提交"/>

        </form>

    </body>

</html>

forward2.jsp 功能是将客户端的请求的内容转发给forward3.jsp, 然后将网页forward3.jsp返回给客户端, forward2.jsp的代码如下:

<%@page contentType="text/html" pageEncoding="UTF-8"%>

<!DOCTYPE html>

<html>

    <head>

        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

        <title>Forward2</title>

    </head>

    <body>

        <h1>Forward2</h1>

        <%

            RequestDispatcher rd = request.getRequestDispatcher("forward3.jsp");

            rd.forward(request, response);

        %>

    </body>

</html>

forward3.jsp是用来返回给客户端的, 代码如下:

<%@page contentType="text/html" pageEncoding="UTF-8"%>

<!DOCTYPE html>

<html>

    <head>

        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

        <title>Forward3</title>

    </head>

    <body>

        <h1>Forward3</h1>

        <%

            String username = request.getParameter("username");

        %>

        用户名为: <%=username %>

    </body>

</html>
