Struts2之Validator

Struts2中提供了数据校验验证数据例如验证邮件、数字等。验证方式有3种:一是通过validate()方法，二是通过Xml，三是使用注解方式。

一、初始化

首先定义一个User类

package com.cyw.test;

import java.util.Date;

public class User {

    private String name;
    private int age;
    private String email;
    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 String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public Date getBirthDay() {
        return birthDay;
    }
    public void setBirthDay(Date birthDay) {
        this.birthDay = birthDay;
    }
    private Date birthDay;

}
