本文介绍了一个基于JavaServer Faces (JSF) 的简单登录系统实现。该系统包括前端页面、后端逻辑处理及数据库交互等内容。通过UserBean进行登录验证，并利用Hibernate框架完成数据持久化操作。

源文件结构

web文件结构

1 UserBean.java

package officeautomatic;

import javax.faces.event.ActionEvent;

public class UserBean {

private Integer id;

private String name;

private String pass;

private String err;

private UserDAO userDAO;

private String outcome;

public void setId(Integer id) {

this.id = id;

}

public Integer getId() {

return id;

}

public void setName(String name) {

this.name = name;

}

public String getName() {

return name;

}

public void setPass(String pass) {

this.pass = pass;

}

public String getPass() {

return pass;

}

public void setErr(String err) {

this.err = err;

}

public String getErr() {

return err;

}

public void setUserDAO(UserDAO userDAO) {

this.userDAO = userDAO;

}

public UserDAO getUserDAO() {

return userDAO;

}

public void checkValue(ActionEvent e) {

if((getUserDAO().find(id) != null) && pass.equals(getUserDAO().find(new Integer(id)).getPass())){

setName(getUserDAO().find(new Integer(id)).getName());

outcome = "success";

}

else{

setErr("error!");

outcome = "failure";

}

public String outcome(){

return outcome;

}

checkValue方法里由id搜索，核对password的过程想推荐使用单独的UserValidator类。

2 IUserDAO.java

package officeautomatic;

public interface IUserDAO {

public UserBean find(Integer id);

}

3 UserDAO.java

package officeautomatic;

import org.hibernate.Hibernate;

import org.hibernate.Session;

import org.hibernate.SessionFactory;

public class UserDAO implements IUserDAO {

private SessionFactory sessionFactory;

public UserDAO() { }

public UserDAO(SessionFactory sessionFactory) {

this.setSessionFactory(sessionFactory);

}

public void setSessionFactory(SessionFactory sessionFactory) {

this.sessionFactory = sessionFactory;

}

public UserBean find(Integer id) {

Session session = sessionFactory.openSession();

UserBean userBean = (UserBean) session.get(UserBean.class, id);

Hibernate.initialize(userBean);

session.close();

return userBean;

}

actionListener作为JSF的监听器，返回void。
