package com.structs2;

import java.util.Date;
import java.util.regex.Pattern;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;

public class HelloWordAction extends ActionSupport {
    private String name;
    private String mobile;




    private Date birthday;                //当输入数据时，如果不能转换为Date型数据，则也会把错
    public Date getBirthday() {            //误信息添加到FieldError中，并且自动进入input视图
        return birthday;
    }
    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }





    public String getName() {
        return name;
    }

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

    public String getMobile() {
        return mobile;
    }

    public void setMobile(String mobile) {
        this.mobile = mobile;
    }

    public String save() {
        ActionContext.getContext().put("name", name);
        ActionContext.getContext().put("mobile", mobile);
        ActionContext.getContext().put("message", "保存成功");
        return "success";
    }

    public String update() {
        ActionContext.getContext().put("name", name);
        ActionContext.getContext().put("mobile", mobile);
        ActionContext.getContext().put("message", "更新成功");
        return "success";
    }


      //手工编写代码对所有Action进行校验 public void validate()
     //对Action所有方法进行校验,需要继承ActionSupport类
    public void validate() {// 对Action update方法进行校验,需要继承ActionSupport类
        if (name == null || "".equals(name.trim()))
            this.addFieldError(name, "用户名不能为空");// 会往fieldError集合中添加错误信息struts会将转化到input视图
        if (mobile == null || "".equals(mobile.trim())) // 默认放在input视图中
            this.addFieldError(mobile, "手机号不能为空");
        else if (!Pattern.compile("^1[358]\\d{9}$").matcher(mobile).matches())// 通过正则表达式来实现
            this.addFieldError(mobile, "手机号格式不正确");
    }

    // 手工编写代码对Action指定方法进行校验
