关于HbernateTemplate的简单用法

package com.fengqing.dao.impl;

import java.util.List;

import org.springframework.orm.hibernate3.HibernateTemplate;

import com.fengqing.dao.UserDao;
import com.fengqing.model.User;

public class UserDaoImpl implements UserDao {

public HibernateTemplate hibernateTemplate;

public HibernateTemplate getHibernateTemplate() {
return hibernateTemplate;
}

public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}

//保存
@Override
public void save(User user) {
hibernateTemplate.save(user);
}

//删除
public void delete(int id){
Object object = hibernateTemplate.get(User.class, id);
hibernateTemplate.delete(object);
}

@Override
public void update(User user) {
hibernateTemplate.update(user);
}

@Override
public List<User> getAll() {
List<User> list = (List<User>)hibernateTemplate.find("from User");
return list;
}
}
