name size code gets 列表 sets -type 頁面 list 案例需求：定義一個javaBean叫XdlUser，有四個字段int id、String name、int age、double salary。寫一個jsp頁面，在頁面中構建一個列表對象，裏面存放幾個XdlUser類型的對象。
案例實現：
● XdlUser類
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代碼
