所有实验代码https://gitee.com/sukels/usts-java-ee一、实验目的

1、理解 JavaBean 的作用;

2、能够定义 JavaBean;

3、能在 JSP 页面中使用 JavaBean。

二、实验内容

1、实现功能说明:以用户注册信息页面为例,定义一个用户信息 JavaBean 并在JSP页面中通过jsp中通过直接访问或标签两种形式进行调用。实现下列功能:

(a)创建一个用户注册信息输入页面,用户输入信息包括:姓名、学号、登录密码、性别、年龄、籍贯、选修课程以及个人简介,其中性别为布尔值、选修课程为多选;

(b)定义用户信息JavaBean,其内容与用户注册表单相一致;

(c)创建一个用户信息保持页面,在JSP中使用标签形式,根据前一个页面提交的注册信息构造用户信息JavaBean对象,注意设置其作用范围;

(d)创建一个用户登录以及验证页面,用户通过输入姓名和密码来进行系统登录,当用户名和密码与JavaBean中的信息一致时允许登录,否则输出错误信息或转向错误页面。

2、实验要求:设计代码验证上述方法并调试程序是否正常运行
