Java 实战项目之仓库管理系统的实现流程
作者：qq_1334611189
读万卷书不如行万里路，只学书上的理论是远远不够的，只有在实战中才能获得能力的提升，本篇文章手把手带你用java+SSM+jsp+mysql+maven实现一个仓库管理系统,大家可以在过程中查缺补漏，提升水平
一、项目简述
功能包括： 仓库管理，出入库管理，仓库人员管理，基本信息管理, 供应商信息，系统管理等等。
二、项目运行
环境配置： Jdk1.8 + Tomcat8.5 + mysql + Eclispe (IntelliJ IDEA,Eclispe,MyEclispe,Sts 都支持)
项目技术： JSP +Spring + SpringMVC + MyBatis + html+ css + JavaScript + JQuery + Ajax + layui+ maven等等。
