上班打卡--- 通过批处理命令执行jar文件来记录上班时间

如果 一个程序员要记录自己上班工作时间的话 ,还需要靠手动去记录, 那就有点 不够范了, 程序员自然要有自己的极客范儿 , 下面就跟我一起来(zhuangbi);

先列一下整体的步骤:

1: 先做一个jar文件, 通过执行这个jar文件可以将上下班时间 写入数据库中;

2: 再写一个批处理脚本,能通过批处理命令来执行这个jar文件;

3: 将批处理文件做开机启动执行处理;

1: 先写一个可执行jar:

原理: 通过jdbc操作数据库,

那就上代码吧:

执行Maven clean  >> Maven install >> Maven package ;

使用这个带依赖关系的jar包,并更名为daka.jar ;

先使用 cmd 命令行执行一下 ;

执行结果如下, 没有报错说明执行成功了;

2: 写批处理脚本;

echo off
cd/d "C:\Users\Administrator\Desktop"
java -jar daka.jar
pause

上面脚本的注释:

1: echo off  :关闭打印输出;

2: cd/d 打开目录 "C:\Users\Administrator\Desktop"  目录文件路径;

3: java -jar daka.jar  执行 daka.jar 的 cmd命令 ;

4: pause 暂停 ; 不然的话 就会一闪而过 ;

OK  执行结果如下:

3: 再下面一步: 设置成为开机启动时执行:

将脚本放到开机启动的文件夹下即可开机启动:

如果找不到路径 有肯能是隐藏了; 需要显示隐藏文件;
