这个表单简单实现了用户名+密码的参数传递。
在该页提交了用户名和密码之后，会跳转到另一个页面SetPropertyDemo.jsp，输出提交的用户信息。
SetPropertyDemo.jsp的代码如下：
1 <%@ page language="java" contentType="text/html; charset=utf-8" 2 pageEncoding="utf-8" import="java.util.*" %> 3 <%@ page import="java.sql.*" %> 4 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 5 <html> 6 <head> 7 <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> 8 <title>设置JavaBean属性</title> 9 </head> 10 <body> 11 <jsp:useBean id="user" scope="page" class="chapter7.UserBean"></jsp:useBean> 12 <jsp:setProperty property="*" name="user"/> 13 <% 14 out.println("用户名："+user.getUsername()+"<br/>"); 15 out.println("用户密码："+user.getPassword()); 16 %> 17 </body> 18 </html>
