本系统实现简单的仓库管理功能，可以对仓库及产品信息进行登记、修改、删除等。
程序的基本功能：
1．增加、修改、删除一个仓库资料。
2．增加、修改、删除一个产品资料。
3．按条件显示仓库资料（条件有按编号、名称等）。
4．按条件显示产品资料（条件有按编号、名称等）。
5．查找指定产品的数量。
6 . 用户登录以及退出
基本要求就是这些，我们还在此基础对功能以及界面进行优化，以三颗松鼠为参考对象，进行设计。废话不多说先上运行截图。
一、登录界面
二、主页界面
三、部分功能展示
功能就不一一展示了。
接下来就是数据库方面的设计了。
数据库中的表太多，我们这里就展示一两个表吧。
源码展示（源码太多，这里只展示部分代码）
一、数据库链接
package com.szss.dao; import java.sql.*; public class GetConnection { private Connection con; //定义数据库连接类对象 private PreparedStatement pstm; private String user="sa"; //连接数据库用户名 private String password="123456"; //连接数据库密码 private String className="com.microsoft.sqlserver.jdbc.SQLServerDriver"; //数据库驱动 private String url="jdbc:sqlserver://localhost:1433;DatabaseName=db_supermarket"; //连接数据库的URL public GetConnection(){ try{ Class.forName(className); }catch(ClassNotFoundException e){ System.out.println("加载数据库驱动失败！"); e.printStackTrace(); } } /**创建数据库连接*/ public Connection getCon(){ try { con=DriverManager.getConnection(url,user,password); //获取数据库连接 } catch (SQLException e) { System.out.println("创建数据库连接失败！"); con=null; e.printStackTrace(); } return con; //返回数据库连接对象 } public void doPstm(String sql,Object[] params){ if(sql!=null&&!sql.equals("")){ if(params==null) params=new Object[0]; getCon(); if(con!=null){ try{ System.out.println(sql); pstm=con.prepareStatement(sql,ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY); for(int i=0;i<params.length;i++){ pstm.setObject(i+1,params[i]); } pstm.execute(); }catch(SQLException e){ System.out.println("doPstm()方法出错！"); e.printStackTrace(); } } } } public ResultSet getRs() throws SQLException{ return pstm.getResultSet(); } public int getCount() throws SQLException{ return pstm.getUpdateCount(); } public void closed(){ try{ if(pstm!=null) pstm.close(); }catch(SQLException e){ System.out.println("关闭pstm对象失败！"); e.printStackTrace(); } try{ if(con!=null){ con.close(); } }catch(SQLException e){ System.out.println("关闭con对象失败！"); e.printStackTrace(); } } }
二、主页界面显示
