其实根本没有任何.html文件，都被spring映射成其它的了。

package com.sprhib.dao;

import java.util.List;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import com.sprhib.model.Team;

@Repository
public class TeamDAOImpl implements TeamDAO {

@Autowired
private SessionFactory sessionFactory;

private Session getCurrentSession() {
return sessionFactory.getCurrentSession();
}

public void addTeam(Team team) {
getCurrentSession().save(team);
}

public void updateTeam(Team team) {
Team teamToUpdate = getTeam(team.getId());
teamToUpdate.setName(team.getName());
teamToUpdate.setRating(team.getRating());
getCurrentSession().update(teamToUpdate);

}

public Team getTeam(int id) {
Team team = (Team) getCurrentSession().get(Team.class, id);
return team;
}

public void deleteTeam(int id) {
Team team = getTeam(id);
if (team != null)
getCurrentSession().delete(team);
}

@SuppressWarnings("unchecked")
public List<Team> getTeams() {
return getCurrentSession().createQuery("from Team").list();
}

}
