mvc模式中各种类的作用

po类：只有属性值和setget方法，用于存储数据库中提取的数据，一般属性名称与数据库中列标题相同
在控制层和业务层传递

package com.neuedu.po;

import java.sql.Date;

public class UserinfoPO {
	
	private int sno;
	private String sname;
	private Date birthday;
	private int sex;
	private String lname;
	private String lpass;
	
	public int getSno() {
		return sno;
	}
	public void setSno(int sno) {
		this.sno = sno;
	}
	public String getSname() {
		return sname;
	}
	public void setSname(String sname) {
		this.sname = sname;
	}
	public Date getBirthday() {
		return birthday;
	}
	public void setBirthday(Date birthday) {
		this.birthday = birthday;
	}
	public int getSex() {
		return sex;
	}
	public void setSex(int sex) {
		this.sex = sex;
	}
	public String getLname() {
		return lname;
	}
	public void setLname(String lname) {
		this.lname = lname;
	}
	public String getLpass() {
		return lpass;
	}
	public void setLpass(String lpass) {
		this.lpass = lpass;
	}

}

vo类：视图层和控制层之间传递

package com.neuedu.vo;

import java.sql.Date;

public class RegistVO {
	
	private String lname;
	private String lpass;
	private String sname;
	private Date birthday;
	private int sex;
	
	public String getLname() {
		return lname;
	}
	public void setLname(String lname) {
		this.lname = lname;
	}
	public String getLpass() {
		return lpass;
	}
	public void setLpass(String lpass) {
		this.lpass = lpass;
	}
	public String getSname() {
		return sname;
	}
	public void setSname(String sname) {
		this.sname = sname;
	}
	public Date getBirthday() {
		return birthday;
	}
	public void setBirthday(Date birthday) {
		this.birthday = birthday;
	}
	public int getSex() {
		return sex;
	}
	public void setSex(int sex) {
		this.sex = sex;
	}
}
