题目：设计一个简单的网上名片管理系统，实现名片的增、删、改、查及回收站等操作。

1．用户登录与注册模块
系统的使用者必须是注册用户，一个注册用户需要注册的信息有：用户登录名、密码、用户真实名字等信息。该模块具有两个功能：
（1）用户登录：在登录时，如果用户名和密码正确，进入系统页面。
（2）用户注册：新用户应该先注册，然后再登录该系统。

2．名片管理模块
一个名片包含信息有：序号（id）、姓名（name）、性别（sex）、电话（tel）等有关信息，需要完成对名片有关的管理操作，主要有：
（1）增加名片：增加名片信息到数据库内。
（2）修改名片：修改名片信息。
（3）查询名片：以模糊查询方式查询名片。
（4）删除名片：名片的删除由2种方式，即把名片移到回收站，把名片彻底删除。
（5）浏览/查询：可以模糊查询、浏览目前有效的名片。

3．回收站管理模块
（1）还原：把回收站中的名片还原回收。
（2）彻底删除：把名片彻底从回收站删除。
（3）浏览/查询：可以模糊查询、浏览回收站中的名片。

注：序号（id）在此名片表中具有唯一性，不可重复。

1.系统设计前准备：

    （1）所用技术：HTML+JSP+MySQL+JDBC(可使用CSS和JavaScript优化美观页面)

    （2）使用环境：Eclipse

    （3）MySQL端口号：13306(此为自己设置的，大部分为3306)

    （4）创建数据库（root01）

             该数据库下有三个表，如下：


名片表(idcard)，回收站表(recycle)

账号密码表(root01_01)

 2.注册页面：
