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"
