1 、功能描述 基于SSM的二手交易管理系统1拥有两种角色
管理员商品管理、订单管理、充值管理、用户管理等用户发布商品、查看闲置、充值账户、查看所有订单、发布求购信息、修改个人信息、关注列表等
1.1 背景描述 二手交易管理系统是一个基于SSMSpring SpringMVC MyBatis的Web应用程序旨在提供一个方便、高效的平台用于管理二手商品交易。该系统包括用户管理、商品管理、订单管理、支付管理等功能。 系统采用Spring框架作为整体架构通过SpringMVC模块进行请求处理和数据传递使用MyBatis作为持久层框架实现数据的持久化。系统还采用了MySQL数据库进行数据存储并使用Tomcat服务器进行部署。 用户管理模块负责管理用户信息包括用户注册、登录、找回密码等功能。商品管理模块负责管理二手商品信息包括商品的添加、修改、删除等功能。订单管理模块负责管理订单信息包括订单的生成、支付、发货等功能。支付管理模块负责管理支付信息包括支付方式的添加、修改、删除等功能。 该系统具有友好的用户界面和灵活的功能设计可满足不同用户的需求。通过该系统用户可以更加方便地进行二手商品交易提高交易的效率和安全性。
2、项目技术
后端框架SSMSpring、SpringMVC、Mybatis
前端技术Bootstrap、jsp、css、JavaScript、JQuery
2.1 SSM SSMSpringSpringMVCMyBatis是目前比较主流的Java EE企业级框架适用于搭建各种大型的企业级应用系统。其中Spring就像是整个项目中的粘合剂负责装配bean并管理其生命周期实现控制反转IoC的功能。SpringMVC负责拦截用户请求通过DispatcherServlet将请求匹配到相应的Controller并执行。而MyBatis则是对JDBC的封装让数据库底层操作变得透明通过配置文件关联到各实体类的Mapper文件实现了SQL语句映射。
2.2 mysql MySQL是一款Relational Database Management System直译过来的意思就是关系型数据库管理系统MySQL有着它独特的特点这些特点使他成为目前最流行的RDBMS之一MySQL想比与其他数据库如ORACLE、DB2等它属于一款体积小、速度快的数据库重点是它符合本次毕业设计的真实租赁环境拥有成本低开发源码这些特点这也是选择它的主要原因。
3、开发环境
JAVA版本JDK1.8IDE类型IDEA、Eclipse都可运行tomcat版本Tomcat 7-10版本均可数据库类型MySql5.x和8.x版本都可maven项目否硬件环境Windows 或者 Mac OS
