自己做的spring+hibernate+dwr+js+html小例子

很有段时间没有研究代码了，这几天自己动手写了一个小练习，主要用到的技术有
spring
hibernate
dwr
js
html

现将代码共享出来，希望对研究以上技术的朋友们有点帮助，互相学习！！！

下面进行下分解介绍
数据访问层
UserDao.java:

public interface UserDao  {

void save(User user);
void delete(Integer userid);
void update(User user);
List<User> findUsers();
User getUser(Integer userid);
}


UserDaoImpl.java:

package com.testproject.dao.impl;

import java.util.List;

import javax.annotation.Resource;

import org.hibernate.SessionFactory;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

import com.testproject.dao.UserDao;
import com.testproject.model.User;
/**

@Transactional
public class UserDaoImpl implements UserDao {

@Resource
private SessionFactory sessionFactory;

public void delete(Integer userid) {
  sessionFactory.getCurrentSession().delete(
    sessionFactory.getCurrentSession().load(User.class, userid));

}

public void save(User user) {
  sessionFactory.getCurrentSession().persist(user);

}

@Transactional(propagation = Propagation.NOT_SUPPORTED, readOnly = true)
@SuppressWarnings("unchecked")
public List<User> findUsers() {
  return sessionFactory.getCurrentSession().createQuery("from User")
    .list();
}

@Transactional(propagation = Propagation.NOT_SUPPORTED, readOnly = true)
public User getUser(Integer userid) {

    .get(User.class, userid);
