Java小项目之：旅游网站
旅游网站应用到的技术：
1．Hibernate
2．Tomcat Servlet
3．Jsp，javaScript，jquery , Ajax,EL表达式

前台功能：
1用户的注册和登录，
2旅游线路的报名（一人只能报一条线路）；
3用户对每条旅游线路的评论。
4查询一个城市的所有线路
5查询单一的一条线路

后台管理功能：
1旅游线路的增删改查
2对用户评论的删除或回复
3删除查询用户

部分代码展示：

import java.util.Set;

import org.hibernate.Transaction;

import util.HibernateUtil;

import dao.ManagerDAOImpl;
import entity.Manage;
