JSF注册例子

实体bean

package com.ljh.bean;

public class User implements java.io.Serializable{
    private static final long serialVersionUID = -6904888263734117634L;
    private Integer id;
    private String username;
    private String password;
    
    public User() {}
    
    public User(String username, String password) {
        this.username = username;
        this.password = password;
    }
    
    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 Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }

}

hibernate 映射 (user.hbm.xml 放在com.ljh.hbm包下)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >

dao接口

package com.ljh.dao;

import com.ljh.bean.User;

public interface UserDao {
    public void save(User user);
    public User findUser(String username);
}

dao实现类

package com.ljh.dao.impl;

import java.util.List;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.ljh.bean.User;
import com.ljh.dao.UserDao;

public class UserDaoImpl extends HibernateDaoSupport implements UserDao{

            return null;
        }
        return (User)list.get(0) ;
    }

serviceDao 接口
package com.ljh.service.dao;

import com.ljh.bean.User;


public interface UserServiceDao {
    public void save(User user);
    public boolean isExist(String username);
}

serviceDao 接口实现类

package com.ljh.service.dao.impl;

import com.ljh.bean.User;
import com.ljh.dao.UserDao;

public class UserServiceDaoImpl implements com.ljh.service.dao.UserServiceDao{
    private UserDao userDao;
    public UserDao getUserDao() {

    @Override
    public boolean isExist(String username) {
        User user = userDao.findUser(username);
        if(user==null){
            return false;
