一个ssm综合小案例-商品订单管理-第一天

项目需求分析:

功能需求:登录,商品列表查询,修改

 

项目环境及技术栈:

项目构成及环境:
本项目采用 maven 构建
环境要求:
IDEA  Version: 2017.2.5
Tomcat Version: 8.5.x      >
用到的技术
IOC 容器 spring,
前端web控制层 springmvc,
持久层: mybatis  --> mysql 
技术栈: J2EE 一系列规范

正式开发:
1、使用 IDEA + maven 搭建整合的 ssm 框架
File --> New Project (注意勾选 Create from archetype 使用模板方便自动生成 webapp 等目录)
特别需要注意的是应该选 maven-archetype-webapp
这个而不应该选另外一个cocoon-22-archetype-webapp

 

一路 next 点击创建后 稍微等待一下,等待 mvn 后台构建项目,如果中间被打断很可能会出现未知的异常

接下来,就是配置 pom.xml 项目管理文件了,这部分如果不知道如何操作可以单独学习一下 maven 项目管理

主要是 依赖包(dependency)的配置以及 properties (项目构建编码,jar 包版本号等属性)

web.xml 配置文件

 

 

 

 

mapper.xml 文件编写

<sql id="where_name_password">
<where>
<if test="name!=null and name!='' and password!=null and password!=''">
name=#{name} and password=#{password}
</if>
<!--可惜没有 else 所以这里换成 choose when otherwise 进行判断-->

</where>

 

 

mysql  脚本

drop schema if exists gom;
CREATE SCHEMA gom;
use gom;


drop table if exists t_user;
-- 用户表
create table t_user(
  id int auto_increment primary key,
  email varchar(25),
  name varchar(20),
  password varchar(20),  
  -- md5 存储,
  reg_ip varchar(30),
  reg_date datetime
) ;


-- 登录日志信息表
-- 如果已经有 user_id 存在于 loginfo表则更新之,否则插入

drop table  if exists t_loginfo;
create table t_loginfo(
  user_id int,
  login_ip varchar(30),
  login_date datetime,
  FOREIGN KEY(user_id) references t_user(id)

--  在未开发注册页面之前插入一条测试数据alter
insert into t_user(id,email, name , password , reg_ip  ,  reg_date )
