JSP中forward用法

作者：佚名      jsp网站建设开发编辑：admin      更新时间：2022-07-23

1.首页（填写姓名）(可选，表单post到time.jsp即可)：

略

2.判断时间forward到不同页面：

time.jsp:

<%--
    Document   : index
    Created on : 2009-10-3, 15:48:00
    Author     : lucifer
--%>

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
   "http://www.w3.org/TR/html4/loose.dtd">
<%@page import="java.util.Date" %>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
        <%
               Date dat =
                       new Date();
               if(dat.getHours() <= 12){
                    %>
                    <jsp:forward page="AmGreeting.jsp"/>
         <%}
               else{
                    %>
                    <jsp:forward page="PmGreeting.jsp"/>
                    <%}
         %>
    </body>
</html>

3.如果是早上：

AmGreeting.jsp:

<%--
    Document   : AmGreeting
    Created on : 2009-10-3, 16:00:10
    Author     : lucifer
--%>

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
   "http://www.w3.org/TR/html4/loose.dtd">

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
        <h1>Good Morning! </h1>
        <%
               String name = request.getParameter("userName");
               out.PRintln(name);
         %>
         !!!
    </body>
</html>

如果是下午：

PmGreeting.jsp:

<%--
    Document   : AmGreeting
    Created on : 2009-10-3, 16:00:10
    Author     : lucifer
--%>

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
   "http://www.w3.org/TR/html4/loose.dtd">

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
        <h1>Good Afternoon! </h1>
        <%
               String name = request.getParameter("userName");
               out.println(name);
         %>
         !!!
    </body>
</html>
