简单的基于Struts2的用户注册模块的实现

利用Struts2实现简单的用户注册功能，并具备输入字符的校验功能。

以下index.jsp为首页，显示注册表单：

<%--  首页，显示注册表单--%><%@ taglib prefix="s" uri="/struts-tags" %><%@ page contentType="text/html;charset=UTF-8" language="java" %><html><head>    <title>Java web实验五</title></head><body><form action="register.action" method="post">    <table>        <tr>            <td>用户名：</td>            <td><input type="text" name="username"></td>        </tr>        <tr>            <td>密码：</td>            <td><input type="password" name="upassword"></td>        </tr>        <tr>            <td>确认密码：</td>            <td><input type="password" name="repassword"></td>        </tr>        <tr>            <td>姓名：</td>            <td><input type="text" name="name"></td>        </tr>        <tr>            <td>年龄：</td>            <td><input type="text" name="age"></td>        </tr>        <tr>            <td>出生日期：</td>            <td><input type="text" name="birth"></td>        </tr>        <tr>            <td>邮箱地址：</td>            <td><input type="text" name="email"></td>        </tr>        <tr>            <td><input type="submit" value="提交"></td>            <td><input type="reset" value="重置"></td>        </tr>    </table>    <s:actionerror/></form></body></html>

以下部分为ShowUserInfo.jsp，显示用户注册后的信息：

<%--  Created by IntelliJ IDEA.  User: 23832  Date: 2017/5/15  Time: 19:33  To change this template use File | Settings | File Templates.--%><%@ page contentType="text/html;charset=UTF-8" language="java" %><html><head>    <title>Java web实验五</title></head><body>用户名：${username}<br>密码：${upassword}<br>确认密码：${repassword}<br>姓名：${name}<br>年龄：${age}<br>出生日期：${birth}<br>邮箱地址：${email}<br></body></html>

以下为RegisterAction.java，注册的业务逻辑部分：

package com;import com.opensymphony.xwork2.ActionSupport;import java.util.regex.Pattern;public class RegisterAction extends ActionSupport {    private String username;    private String upassword;    private String repassword;    private String name;    private String age;    private String birth;    private String email;    public String getUsername() {        return username;    }    public void setUsername(String username) {        this.username = username;    }    public String getUpassword() {        return upassword;    }    public void setUpassword(String upassword) {        this.upassword = upassword;    }    public String getRepassword() {        return repassword;    }    public void setRepassword(String repassword) {        this.repassword = repassword;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public String getAge() {        return age;    }    public void setAge(String age) {        this.age = age;    }    public String getBirth() {        return birth;    }    public void setBirth(String birth) {        this.birth = birth;    }    public String getEmail() {        return email;    }    public void setEmail(String email) {        this.email = email;    }    @Override    public void validate() {//字符校验        if (upassword == null || "".equals(upassword)) {//判断输入密码是否为空            this.addActionError("密码必须输入");        }        if (repassword == null || "".equals(repassword)) {//判断确认密码是否为空            this.addActionError("确认密码必须输入");        }        if (upassword != null && repassword != null && !repassword.equals(upassword)) {//判断密码和确认密码是否相同            this.addActionError("密码必须和确认密码相同");        }        Pattern pattern = Pattern.compile("[0-9]*");        if (age==null||"".equals(age)){//判断年龄是否为空            this.addActionError("年龄不能为空");        }        if (age!=null&&!pattern.matcher(age).matches()) {//利用正则表达式判断年龄是否为数字            this.addActionError("年龄必须为数字");        }        if (email==null||"".equals(email)){//判断邮箱是否为空            this.addActionError("邮箱不能为空");        }        if (email!=null&&!Pattern.matches("[a-zA-Z0-9_-]*@([a-zA-Z0-9-_]+"+"\\.)+(com|gov|net|com\\.cn|edu\\.cn)",email)) {//利用正则表达式判断邮箱格式是否正确            this.addActionError("邮箱格式不正确");        }    }    public String execute() throws Exception {        return "success";    }}

以下为Struts2的配置部分：

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC        "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"        "http://struts.apache.org/dtds/struts-2.3.dtd"><struts>    <package name="struts2" extends="struts-default">        <action name="register" class="com.RegisterAction">            <!--定义处理结果与试图资源之间的关系-->            <result name="success">/ShowUserInfo.jsp</result>            <result name="input">/index.jsp</result>        </action>    </package></struts>

web.xml文件配置就不列出了。
