本文實(shí)例為大家分享了struts2和hibernate實(shí)現(xiàn)登錄和注冊(cè)功能，供大家參考，具體內(nèi)容如下
10年積累的成都做網(wǎng)站、成都網(wǎng)站建設(shè)經(jīng)驗(yàn)，可以快速應(yīng)對(duì)客戶對(duì)網(wǎng)站的新想法和需求。提供各種問(wèn)題對(duì)應(yīng)的解決方案。讓選擇我們的客戶得到更好、更有力的網(wǎng)絡(luò)服務(wù)。我雖然不認(rèn)識(shí)你，你也不認(rèn)識(shí)我。但先網(wǎng)站設(shè)計(jì)后付款的網(wǎng)站建設(shè)流程，更有廈門(mén)免費(fèi)網(wǎng)站建設(shè)讓你可以放心的選擇與我們合作。
1、該項(xiàng)目使用MySQL數(shù)據(jù)庫(kù)，數(shù)據(jù)庫(kù)名為test，表名info，如圖所示：
2、配置web.xml（Struts2使用）
<?xml version="1.0" encoding="UTF-8"?>
struts2
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
struts2
/*
index.jsp
3、編寫(xiě)視圖組件（JSP頁(yè)面）
(1)登錄頁(yè)面login.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<s:text name="基于SH的登錄注冊(cè)系統(tǒng)" />
(2)登陸成功頁(yè)面success.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
Insert title here
(3)注冊(cè)頁(yè)面register.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
Insert title here
4、業(yè)務(wù)控制器Action
(1)登錄頁(yè)面對(duì)應(yīng)的業(yè)務(wù)控制器LoginAction.java
其中，重寫(xiě)valiadate()方法，進(jìn)行手工驗(yàn)證
package loginRegisterAction;
import java.util.List;
import loginRegisterDao.LoginRegisterInfo;
import PO.UserInfoPO;
import com.opensymphony.xwork2.ActionSupport;
public class LoginAction extends ActionSupport{
private String userName;
private String password;
private String message="error";
private List list;
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public void validate(){
if(this.getUserName()==null||this.getUserName().length()==0){
addFieldError("userName", "用戶名不能為空!");
}else{
LoginRegisterInfo info= new LoginRegisterInfo();
list=info.queryInfo("userName", this.getUserName());
if(list.size()==0){
addFieldError("userName", "該用戶尚未注冊(cè)");
}else{
UserInfoPO ui=new UserInfoPO();
for(int i=0;i(2)注冊(cè)頁(yè)面對(duì)應(yīng)的業(yè)務(wù)控制器RegisterAction.java
package loginRegisterAction;
import java.util.List;
import loginRegisterDao.LoginRegisterInfo;
import PO.UserInfoPO;
import com.opensymphony.xwork2.ActionSupport;
public class RegisterAction extends ActionSupport {
private String userName;
private String password1;
private String password2;
private String mess=ERROR; //ERROR等同于"error"
private List list;
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword1() {
return password1;
}
public void setPassword1(String password1) {
this.password1 = password1;
}
public String getPassword2() {
return password2;
}
public void setPassword2(String password2) {
this.password2 = password2;
}
public void validate(){
if(this.getUserName()==null||this.getUserName().length()==0){
addFieldError("userName", "用戶名不能為空！");
}else{
LoginRegisterInfo info= new LoginRegisterInfo();
list=info.queryInfo("userName", this.getUserName());
UserInfoPO ui=new UserInfoPO();
for(int i=0;i5、在struts.xml中配置Action
/login.jsp
/register.jsp
/register.jsp
/success.jsp
/login.jsp
/login.jsp
6、Hibernate的配置文件
使用Hibernate需要通過(guò)Hibernate的配置文件加載數(shù)據(jù)庫(kù)驅(qū)動(dòng)以及與數(shù)據(jù)建立連接，配置文件為hibernate.cfg.xml
com.mysql.jdbc.Driver
jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8
root
org.hibernate.dialect.MySQL5Dialect
7、加載上面Hibernate配置文件的類(lèi)(HIbernateSessionFactory.java)
package addHibernateFile;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class HibernateSessionFactory {
private SessionFactory sessionFactory;
public HibernateSessionFactory(){
}
public SessionFactory config(){
try{
Configuration configuration= new Configuration();
Configuration configure=configuration.configure("hibernate.cfg.xml");
return configure.buildSessionFactory();
}catch(Exception e){
e.getMessage();
return null;
}
}
public Session getSession(){
sessionFactory=config();
return sessionFactory.openSession();
}
}
8、PO對(duì)象以及對(duì)應(yīng)的映射文件(在同一個(gè)包下)
(1)PO對(duì)象的類(lèi)UserInfoPO.Java
package PO;
/*
* PO對(duì)象(持久化對(duì)象)的類(lèi)，與數(shù)據(jù)庫(kù)相對(duì)應(yīng)
*/
public class UserInfoPO {
private int id;
private String userName;
private String password;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
(2) PO對(duì)應(yīng)的映射文件UserInfoPO.hbm.xml
<?xml version="1.0" encoding="utf-8"?>
9、完成登錄和注冊(cè)業(yè)務(wù)功能
將登錄和注冊(cè)業(yè)務(wù)功能封裝到類(lèi)LoginRegisterInfo(JavaBean)中
數(shù)據(jù)庫(kù)操作類(lèi)LoginRegisterInfo.java:
package loginRegisterDao;
/*
* 登錄和注冊(cè)業(yè)務(wù)功能，封裝到這個(gè)JavaBean
*/
import java.util.List;
import javax.swing.JOptionPane;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.Transaction;
import PO.UserInfoPO;
import addHibernateFile.HibernateSessionFactory;
public class LoginRegisterInfo {
private Session session;
private Transaction transaction;
private Query query;
HibernateSessionFactory getSession;
public LoginRegisterInfo(){
}
public String saveInfo(UserInfoPO info){
String mess="error";
getSession=new HibernateSessionFactory();
session=getSession.getSession();
try{
transaction=session.beginTransaction();
session.save(info);
transaction.commit();
mess="success";
return mess;
}catch(Exception e){
message("RegisterInfo.error:"+e);
e.printStackTrace();
return null;
}
}
public List queryInfo(String type,Object value){
getSession=new HibernateSessionFactory();
session=getSession.getSession();
try{
String hqlsql="from UserInfoPO as u where u.userName=?";
query=session.createQuery(hqlsql);
query.setParameter(0, value);
List list=query.list();
transaction=session.beginTransaction();
transaction.commit();
return list;
}catch(Exception e){
message("LoginRegisterInfo類(lèi)中有異常，異常為：:"+e);
e.printStackTrace();
return null;
}
}
public void message(String mess){
int type=JOptionPane.YES_NO_OPTION;
String title="提示信息";
JOptionPane.showMessageDialog(null, mess,title,type);
}
}
