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;
}
}
