java水果商城管理系统（界面框架代码） 前提 - 实现前的准备，需要配置jdbc，导入jdbc驱动jdbc驱动包下载地址：[http://junruocdn.zmide.com/mysql-connector-java-5.1.30.jar](http://junruocdn.zmide.com/mysql-connector-java-5.1.30.jar)注意：如果失效了请之行百度下载！ ## 正文开始 描述 - 本项目模拟真实的超市管理模式，以管理员为面向对象，所要实现的功能是基本的增删改查，具体实现步骤如下： 管理员登录 进入欢迎界面 进入仓库管理界面 管理员进行增删改查 ### 1，定义欢迎界面Welcome.java 描述 - 本界面 主要针对按钮进行了部分优化并设置了面板的背景显示 用户通过点击“进入系统”按钮进入到“登录界面 ```java package com.fruit.main;
