JAVAWeb采购管理系统

采购管理系统

项目构思

简易的管理系统，结构为 Servlet + JSP + MySQL，使用，搭建起了这个项目，源码中有很详细的注释，如果刚开始学习JavaWeb的内容，学一下Servlet SSM ，再搭配这个项目，岂不是美滋滋，有需要就拿去，如果能够有帮助，在fork的同时也赏一个Star吧！

接下来就介绍一下过程：

1. 数据库连接

在这个项目中，并不是单独编写Java程序来连接数据库，而是使用c3p0-config.xml文件来配置数据库连接池，使用 QueryRunner 来执行数据库操作

在运行项目之前，需要在图中所示文件中设置你自己的本地数据库名称和密码，否则，无法连接数据库

运用技术：
SSM + redis + jsp + bootstrap(前台) + layui/bootstrap(后台) + jquery
实现功能：
首页：商品信息+视频播放+广告轮播
用户模块：个人信息+粉丝数量/关注数量
商品模块： 商品分类+商品详情+商品列表分页
资讯模块： 外链接
动态留言模块：发布动态+评论+图片发布
支付模块：微信支付+易宝支付

代码已经上传github，下载地址： https://github.com/21503882/

2. JAR文件

在构建项目时，需要导入所需的Library

3. 建表

在创建数据库时，也需要一张表来配合运行项目，在项目中也给出了这张表的结构

4. 建包

采用MVC设计模式，建包时我分成了这几个方面：

dao
page
product
service
servlet
以及在测试时的用例：demo

接下来介绍这几个包的内容：

1. dao包：
   内含有一个Java文件：ProductDao，编写对于数据库的操作，增删改查之类

2. page包：
   查询后的数据需要分页显示，否则看起来很麻烦，page包中包含有一个Java文件：PageBean，配合content.jsp文件将查询结果分页显示

3. product包：
   内含有Product类，将商品的基本信息封装，便于其他类使用

4. service包
   内含有一个Java文件：ProductService，实现了ProductDao类中定义的方法，并封装，降低程序中的代码重复性，更加简洁

5. servlet包
   内含有ProductServlet，实现了ProductService类中定义的方法，并和JSP页面进行通信

6. demo包
   在完成项目后，需要测试用例来进行测试

5. MVC模式

MVC模式：Model，View，Controller：

Model：ProductDao类，PageBean类和Product类作为基本的模型

View：JSP文件，系统的页面

Controller：ProductServlet，作为用户输入和数据库操作的控制者

这样就使得代码较为简洁

6. 运行前需要的准备

在Github上fork项目，并且clone至本地后，用IDEA打开，并按照这篇配置教程来配置web项目
【JavaWeb】IDEA如何创建及配置Web项目（多图）

配置后，将src目录下的 c3p0-config.xml 文件中的数据库信息改为自己的数据库信息，运行Tomcat，岂不是美滋滋
