问题提出：
package bean;
public class Student {
private Integer id; //学号
private String name; //姓名
private String password; //密码
public Integer getID() { return id; }
public String getName() { return name; }
public String getPassword() { return password; }
public void setID(Integer id) { this.id = id; }
public void setName(String name) { this.name = name; }
public void setPassword(String pwd) { this.password = pwd; }
}而Jsp中的调用代码是通过EL实现，也导入了相应的包。如下：<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<jsp:directive.page import="DAO.StudentDAO"/>
<jsp:directive.page import="java.util.List"/>
<%
List studentList = StudentDAO.listStudents();
request.setAttribute("studentList", studentList);
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>My JSP 'student.jsp' starting page</title>
</head>
<body>
<form action="operateStudent.jsp" method=get>
<table bgcolor="#CCCCCC" cellspacing=1 cellpadding=5 width=100%>
<tr bgcolor=#DDDDDD>
<th>选择</th>
<th>学号</th>
<th>姓名</th>
<th>密码</th>
<th>操作</th>
</tr>
<c:forEach items="${studentList}" var="stu">
<tr bgcolor="#FFFFFF">
<td><input type="checkbox" name="id" value="${stu.id}" /></td>
<td>${stu.id}</td>
<td>${stu.name}</td>
<td>${stu.password}</td>
<td>
<a href="addEmployee.jsp?action=edit&id=${stu.id}">修改</a>
<a href="addEmployee.jsp?action=del&id=${stu.id}"
onclick="return confirm('确定删除?')">删除</a>
</td>
</tr>
</c:forEach>
</table>
</form>
</body>
</html>(1).首先确保循环<c:forEach items="${studentList}" var="stu">，然后调用是${stu.id}、${stu.name}；
(2).然后属性命名最好是小写的，当然首字母一定要小写，如empNo；
(3).在数据库中create table student( stuid int,username varchar(20)
)对应的Student类变量private Integer id; private String name;其中类型需要一致，同时设置get和set方法：
<span style="white-space:pre"> </span>private Integer id; //学号
private String name; //姓名
public Integer getID() { return id; }
public String getName() { return name; }
public void setId(Integer id) { this.id = id; }
public void setName(String name) { this.name = name; }(4).在DAO中数据库增删改查操作中类型要一致，并且对应数据库中的学号stuid和姓名username:而当我修改为public IntegergetId() { return id; }后运行结果如下图所示：
[java] javax.el.PropertyNotFoundException: Property 'id' not found on type bean.Student
