如何用Java代码实现进销存管理系统

本篇文章为大家展示了如何用Java代码实现进销存管理系统，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。

一、项目简述

本系统功能包括： 库存管理，入库管理，出库管理，往来管理，基础资料, 系统管理，消息中心，系统监控等等。

二、项目运行

环境配置： Jdk1.8 + Tomcat8.5 + Mysql + HBuilderX （ Webstorm也 行）+ Eclispe （ IntelliJ IDEA ,Eclispe,MyEclispe , Sts都支持）。

项目技术： Springboot + Maven + Mybatis-plus+ Vue + Redis + Shiro + Druid + logback 组成，B/S模萤；,其他：fastjson, poi, Swagger-ui, quartz, lombok （简化代码）等
