JSTL表格案例

定义一个Member类　将数据存储在list集合 并将数据打印在页面上以表格的形式

 

Member类

package utils;

import java.text.SimpleDateFormat;
import java.util.Date;

public class Member {
    private String name;
    private String gender;
    private int age;
    private Date date;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public Date getDate() {
        return date;
    }

    public void setDate(Date date) {
        this.date = date;
    }

    public Member() {
    }

    public Member(String name, String gender, int age, Date date) {
        this.name = name;
        this.gender = gender;
        this.age = age;
        this.date = date;
    }
    public String getDateformat()
    {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy年MM月dd日 HH时mm分ss秒");
        String format = sdf.format(date);
         return format;

    }
}
