Person.java文件：

package com.neu.domain;

import java.io.Serializable;
import java.util.Date;

public class Person implements Serializable {
    private String name;
    private int age;//基本类型自动转换
    private Date birthday;
    public Person() {
        super();
    }
    public Person(String name, int age, Date birthday) {
        super();
        this.name = name;
        this.age = age;
        this.birthday = birthday;
    }
    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 Date getBirthday() {
        return birthday;
    }
    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }
