前言：
通过这几天在B站上学习的JSP，MVC开发模式，EL表达式，JSTL， 三层架构：软件设计架构 ，等JavaWeb知识，于是乎跟着视频做了一个用户信息管理系统，在此记录一下，以巩固所学知识。
一、需求分析：
1. 简单功能
1. 列表查询 2. 登录 3. 添加 4. 删除 5. 修改2. 复杂功能
1. 删除选中 2. 分页查询 好处： 1. 减轻服务器内存的开销 2. 提升用户体验 3. 复杂条件查询3.登录：
- 调整页面，加入验证码功能
- 代码实现
二、设计：
1. 技术选型：
Servlet+JSP+MySQL+JDBCTempleat+Duird+BeanUtilS+tomcat
2. 数据库设计：
drop database if exists day17;
create database day17;
use day17;
create table user(
id int primary key auto_increment,
name varchar(20) not null,
gender varchar(5),
age int,
address varchar(32),
qq varchar(20),
email varchar(50),
username varchar(20),
password varchar(32)
);
insert into user values(1,"小A","男",20,"北京","112233","[email protected]","小A","123456");
insert into user values(2,"小B","女",20,"上海","112234","[email protected]","小B","123456");
insert into user values(3,"小C","男",20,"北京","112235","[email protected]","小C","123456");
insert into user values(4,"小D","女",20,"上海","112236","[email protected]",null,null);
insert into user values(5,"小E","男",20,"北京","112237","[email protected]",null,null);
insert into user values(6,"小F","女",20,"上海","112238","[email protected]",null,null);
insert into user values(7,"小G","男",20,"北京","112239","[email protected]",null,null);
insert into user values(8,"小H","女",20,"上海","112240","[email protected]",null,null);
insert into user values(9,"小I","男",20,"北京","112241","[email protected]",null,null);
insert into user values(10,"小J","女",20,"上海","112242","[email protected]",null,null);
insert into user values(11,"小K","男",20,"北京","112243","[email protected]",null,null);
insert into user values(12,"小L","女",20,"上海","112244","[email protected]",null,null);
insert into user values(13,"小M","男",20,"北京","112245","[email protected]",null,null);
insert into user values(14,"小N","女",20,"上海","112246","[email protected]",null,null);
insert into user values(15,"小O","男",20,"北京","112247","[email protected]",null,null);
初始我设置系统有三位管理员：小A,小B,小C,密码为123456. （个人随机设置，可以改动）
其他记录为普通用户。
三、开发：
1. 环境搭建
1. 创建数据库环境（mysql8.0）
- 创建数据库:day17;
- user表:存取用户信息
2. 创建项目，导入需要的jar包
2. 编码

五. 部署运维
启动Tomcat服务器。。。。。。
