案例需求：定义一个javaBean叫XdlUser，有四个字段int id、String name、int age、double salary。写一个jsp页面，在页面中构建一个列表对象，里面存放几个XdlUser类型的对象。
案例实现：
● XdlUser类
package com.xdl.bean; public class XdlUser { public XdlUser(int id, String name, int age, double salary) { super(); this.id = id; this.name = name; this.age = age; this.salary = salary; } public XdlUser() { super(); } @Override public String toString() { return "XdlUser [id=" + id + ", name=" + name + ", age=" + age + ", salary=" + salary + "]"; } public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public double getSalary() { return salary; } public void setSalary(double salary) { this.salary = salary; } private int id; private String name; private int age; private double salary; } ● JSP代码 <%@page import="java.util.ArrayList"%> <%@page import="com.xdl.bean.XdlUser"%> <%@page import="java.util.List"%> <%@ page language="java" contentType="text/html; charset=utf-8" 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>Insert title here</title> <style type="text/css"> table { width:600px; text-align: center; border-collapse: collapse; } table,td{ border:1px solid red; } </style> </head> <body> <% List<XdlUser> datas = new ArrayList<XdlUser>(); XdlUser usera = new XdlUser(1,"杜兰特",28,2400); XdlUser userb = new XdlUser(2,"詹姆斯",32,2600); XdlUser userc = new XdlUser(3,"库里",29,1800); XdlUser userd = new XdlUser(4,"莱昂纳德",28,2000); datas.add(usera); datas.add(userb); datas.add(userc); datas.add(userd); %> <table> <tr> <td>ID</td> <td>NAME</td> <td> AGE</td> <td> SALARY</td> </tr> <% for(int i=0;i<datas.size();i++){ XdlUser user = datas.get(i); %> <tr> <td><%=user.getId() %></td> <td><%=user.getName()%></td> <td> <%=user.getAge() %></td> <td> <%=user.getSalary() %></td> </tr> <% } %> </table> </body> </html>
