项目描述：一个简单的超市管理系统，能够实现用户登入和注册功能，共分为前台和后台两个主要界面，普通用户界面操作权限收到限制，只能对商品和销售记录进行简单查询操作，后台中可以进行商品的删除、修改、查询，可以查看用户信息，可以修改用户信息。具体的代码如下：

 TooLUtil工具类：在该类中定义一些方法，用于判断字符串是否为空、获取当前时间、对时间进行格式转化，同时获取当前用户登入，具体代码如下所示：

package cn.qinlimei.goodmanager.utils;import javax.xml.crypto.Data;import java.text.Format;import java.text.SimpleDateFormat;import java.util.Date;/** * 在该类中定义一些方法，用于判断字符串是否为空、获取当前时间、对时间进行格式转化 * 获取当前用户登入 */public class ToolUtil { //判断字符串是否为空 public static boolean isEmpty(String str){ if(str!=null&& !"".equals(str.trim())){//字符串两端的空格去掉 return false;//不是空的返回false } return true;//空的话就返回真 } //获取当前系统时间所对应的毫秒值 public static Long getTime(){ long time=System.currentTimeMillis(); return time; } //将一个long类型的毫秒值转换成指定格式的日期字符串 public static String getDataByTime(long time){ SimpleDateFormat format=new SimpleDateFormat("yyyy-MM-dd"); Date date=new Date(time); String value=format.format(date); return value; }}
