篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了库存物资管理系统相关的知识，希望对你有一定的参考价值。

一、实验思路

在数据库中建立两个表，flow表存放出入库的单据，Warehouse表存放商品的信息。FlowBean类和WarehouseBean类处理所用到的变量；通过FlowDao类和WarehouseDao类进行连接；通com.servlet包中的类进行增删改查的操作.

结构及数据库表如下图所示：

四、遇到的问题

今天连接数据库时总是提示client dose not support authentication protocol requested by server;consider upgrading mysql client

后来通过cmd黑框修改了密码的格式SET PASSWORD FOR -> ‘root‘@‘localhost‘ = OLD_PASSWORD(‘11111‘);问题得到解决；

连接数据库时出现No suitable driver found for jdbc:sql://localhost:3307/choose?useSSL=false错误。后来通过查询在数据库后面加上了

?characterEncoding=utf8&useSSL=true一行代码解决了此问题。
