下面的是对cookieutil工具类各方法的调用演示：
user.java
封装用户信息的javabean对象模型
package com.itcast.bean;
public class user {
private int id;
private string username;
private string password;
public string getpassword() {
return password;
}
public void setpassword(string password) {
this.password = password;
}
public string getusername() {
return username;
}
public void setusername(string username) {
this.username = username;
}
public int getid() {
return id;
}
public void setid(int id) {
this.id = id;
}
}
