一、系统简介
本项目采用eclipse工具开发，jsp+servlet技术编写，样式采用了layui前段框架，数据库采用的是mysql，navicat开发工具。
系统一共分为3个角色分别是：管理员，仓管员，供应商
二、模块简介
管理员
1、登录
2、仓管员管理
3、仓库管理
4、供应商管理
5、商品管理
6、出库入库管理
仓管员
1、登录
2、个人信息维护
3、查看商品信息
4、库存预警
5、商品申请
6、商品供应记录
7、商品出库入库
供应商
1、登录注册
2、个人信息维护
3、商品出库入库申请
4、个人申请记录
获取方式：基于javaweb的仓库管理系统 - 九鸟网

四、代码简介
1、登录
login.jsp中，用户填写用户名和密码，点击登录按钮，提交登录的form表单，请求后台的loginservlet类里面的login方法，验证登录后，跳转指定的页面

}注册代码
用户点击注册按钮，跳转注册页面，填写注册表单，提交代码到SupplierServlet里面addSupplier方法中，后台进行数据库的插入操作，这边注册的是供应商，管理员需要审核通过后，供应商才能登陆
