簡單的基於Struts2的使用者註冊模組的實現
阿新 • • 發佈:2019-02-05
利用Struts2實現簡單的使用者註冊功能,並具備輸入字元的校驗功能。
以下index.jsp為首頁,顯示登錄檔單:

以下部分為ShowUserInfo.jsp,顯示使用者註冊後的資訊:

以下為RegisterAction.java,註冊的業務邏輯部分:
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() {//字元校驗
if (upassword == null || "".equals(upassword)) {//判斷輸入密碼是否為空
this.addActionError("密碼必須輸入");
}
if (repassword == null || "".equals(repassword)) {//判斷確認密碼是否為空
this.addActionError("確認密碼必須輸入");
}
if (upassword != null && repassword != null && !repassword.equals(upassword)) {//判斷密碼和確認密碼是否相同
this.addActionError("密碼必須和確認密碼相同");
}
Pattern pattern = Pattern.compile("[0-9]*");
if (age==null||"".equals(age)){//判斷年齡是否為空
this.addActionError("年齡不能為空");
}
if (age!=null&&!pattern.matcher(age).matches()) {//利用正則表示式判斷年齡是否為數字
this.addActionError("年齡必須為數字");
}
if (email==null||"".equals(email)){//判斷郵箱是否為空
this.addActionError("郵箱不能為空");
}
if (email!=null&&!Pattern.matches("[a-zA-Z0-9_-]*@([a-zA-Z0-9-_]+"+"\\.)+(com|gov|net|com\\.cn|edu\\.cn)",email)) {//利用正則表示式判斷郵箱格式是否正確
this.addActionError("郵箱格式不正確");
}
}
public String execute() throws Exception {
return "success";
}
}
以下為Struts2的配置部分:

<!DOCTYPE struts PUBLIC

"http://struts.apache.org/dtds/struts-2.3.dtd">

<package name="struts2" extends="struts-default">

<result name="success">/ShowUserInfo.jsp</result>
<result name="input">/index.jsp</result>
</action>
</package>
</struts>
web.xml檔案配置就不列出了。
