发际线与我作队-团队作业（五）：冲刺总结4

冲刺总结4--数据库

我组采用的数据库是Mysql

MySQL所使用的 SQL 语言是用于访问数据库的最常用标准化语言。MySQL 软件采用了双授权政策，分为社区版和商业版，由于其体积小、速度快、总体拥有成本低，尤其是开放源码这一特点，一般中小型网站的开发都选择 MySQL 作为网站数据库。
工具准备
- 安装Mysql
- 安装XAMPP

数据库设置

文件类

/*Table structure for table `t_file` */

DROP TABLE IF EXISTS `t_file`;

CREATE TABLE `t_file` (
  `id` int(4) NOT NULL auto_increment,
  `title` varchar(50) default NULL,
  `remark` varchar(1000) default NULL,
  `url` varchar(200) default NULL,
  `inputdate` varchar(50) default NULL,
  `fromuser` int(4) default NULL,
  `touser` int(4) default NULL,
  `status` int(4) default NULL,
  `typeid` int(4) default NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

/*Data for the table `t_file` */

insert  into `t_file`(`id`,`title`,`remark`,`url`,`inputdate`,`fromuser`,`touser`,`status`,`typeid`) values (1,'档案管理','档案管理','2013-03-29-14-46-42F.chm','2013-03-29 14:46:45',3,4,2,1);

共设置了九个文件属性，包括编号、标题、备注、文件名、上传时间、发送者、接受者、文件状态和文件类别
文件类别包括加密和普通

/*Table structure for table `t_filetype` */

DROP TABLE IF EXISTS `t_filetype`;

CREATE TABLE `t_filetype` (
  `id` int(4) NOT NULL auto_increment,
  `typename` varchar(50) default NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

/*Data for the table `t_filetype` */

insert  into `t_filetype`(`id`,`typename`) values (1,'加密'),(2,'普通');

用户类

/*Table structure for table `t_user` */

DROP TABLE IF EXISTS `t_user`;

CREATE TABLE `t_user` (
  `id` int(4) NOT NULL auto_increment,
  `username` varchar(50) default NULL,
  `password` varchar(50) default NULL,
  `realname` varchar(50) default NULL,
  `role` varchar(50) default NULL,
  `departmentid` int(4) default NULL,
  `zhiwei` varchar(50) default NULL,
  `tel` varchar(50) default NULL,
  `email` varchar(50) default NULL,
  `zuzhiid` int(4) default NULL,
  `sex` varchar(50) default NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

/*Data for the table `t_user` */

insert  into `t_user`(`id`,`username`,`password`,`realname`,`role`,`departmentid`,`zhiwei`,`tel`,`email`,`zuzhiid`,`sex`) values (1,'admin','1','管理员','0',NULL,'','13800000000','admin@163.com',NULL,'男'),(2,'xiaoming','1','王明','1',1,'','13800000000','xiaoming@163.com',1,'男'),(3,'xiaohong','1','小红','2',1,'初级职员','13800000000','xiaohong@163.com',1,'女'),(4,'xiaowang','1','小王','2',1,'','13800000000','xiaowang@163.com',1,'男'),(5,'xiaoli','1','小李','1',2,'初级职员','13800000000','xiaoli@163.com1',2,'男');

- 共设置了11个用户属性，包括序号、用户名、密码、真实姓名、角色、单位、职位、电话、邮箱、组织、性别

单位类

- 设置了两个单位

/*Table structure for table `t_department` */

DROP TABLE IF EXISTS `t_department`;

CREATE TABLE `t_department` (
  `id` int(4) NOT NULL auto_increment,
  `departmentname` varchar(50) default NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

/*Data for the table `t_department` */

insert  into `t_department`(`id`,`departmentname`) values (1,'单位1'),(2,'单位2');

登录验证

//获取登录页面的账号、密码
	String username = request.getParameter("username");
	String password = request.getParameter("password");
	String role = request.getParameter("role");
	ResultSet rs = null;
	try{
		String sql = "select * from t_user where  username='"+username.trim()+"'";
		rs = stmt.executeQuery(sql);
	if (rs.next()) {
			if (rs.getString("password").equals(password)&&rs.getString("role").equals(role)) {//账号验证成功
				session.setAttribute("username", username);
				session.setAttribute("realname",rs.getString("realname"));
				session.setAttribute("role",rs.getString("role"));
				session.setAttribute("id", rs.getString("id"));
				session.setAttribute("departmentid",rs.getString("departmentid"));
				response.sendRedirect("../../index.jsp");	
			}else{//账号验证失败跳转登录界面
				response.sendRedirect("../../login.jsp?info=0");
			}
		}else{//账号验证失败跳转登录界面
			response.sendRedirect("../../login.jsp?info=1");
		}
	} catch (Exception e) {
		out.println(e.getMessage());
	} finally {
		if (rs != null) {
			try {
				rs.close();
			} catch (Exception e) {
				e.printStackTrace();
			}
		}
		if (stmt != null) {
			try {
				stmt.close();
			} catch (Exception e) {

		}
		if (conn != null) {
			try {
		conn.close();
			} catch (Exception e) {
		e.printStackTrace();
