本文介绍了一个使用Spring、Hibernate和Struts2框架整合的简单示例项目，详细展示了各层的实现方式，包括DAO层的Hibernate操作、Service层的业务逻辑处理、Action层的请求响应处理等，并提供了核心配置文件的内容。

首先，目录结构大致如下：

Dao:

@Repository
public class UserDaoImpl extends HibernateDaoSupport implements UserDao {

	/**
	 * 注入设置sessionFactory
	 */
	@Autowired
	public void setSessionFacotry(SessionFactory sessionFacotry) {
		super.setSessionFactory(sessionFacotry);
	}

	/**
	 * 根据用户名查询用户
	 */
	public User findUserByUserCode(String userCode) {
		return super.getHibernateTemplate().execute(
				new HibernateCallback<User>() {
					public User doInHibernate(Session session)
							throws HibernateException {
						String hql = "from User where user_code=?";
						Query query = session.createQuery(hql);
						query.setParameter(0, userCode);
						return (User) query.uniqueResult();
					}
				});
	}

	@Override
	public void insertUser(User user) {
		super.getHibernateTemplate().save(user);
	}
}

Service:

@Service
public class UserServiceImpl implements UserService{
	@Autowired
	private UserDao userDao;

	/**
	 * 用户登录
	 */
	public User userLogin(User user) {
		User queryUser = userDao.findUserByUserCode(user.getUser_code());
		if(queryUser == null) {
			throw new RuntimeException("用户不存在");
		}
		if(!queryUser.getUser_password().equals(user.getUser_password())) {
			throw new RuntimeException("密码错误");
		}
		return queryUser;
	}

	/**
	 * 用户注册
	 */
	@Transactional(isolation=Isolation.REPEATABLE_READ,propagation=Propagation.REQUIRED,readOnly=false)
	public void userRegister(User user) {
		userDao.insertUser(user);
	}

}

Action:

@Controller
@Scope("prototype")
public class UserAction extends ActionSupport implements ModelDriven<User> {
	
	private User user = new User();
	@Override
	public User getModel() {
		return user;
	}
	@Autowired
	private UserService userService;
	
	public String login() {
		User queryUser = userService.userLogin(user);
		ActionContext.getContext().getSession().put("user", queryUser);
		return "toHome";
	}

	
}
