mac下使用cron定时调用java文件

1. 写sh文件，内容和执行命令行一致
2. 给sh文件加权限
3. 下载cron，将sh文件放进cron
4. 重启cron
   /* write an sh
   for example you want to execute java file price.class set at /Users/ABC/Desktop/
   you should set followings in your sh file
   */

cd /Users/ABC/Desktop
java price

/*
set name of sh as exe.sh
set authority to your sh file
*/

chmod +x exe.sh

/*
down cron from https://www.drupal.org/project/drupal , set it any place
in your terminal, to input:
*/

crontab -e

//then edit the file, put exe.sh into cron

*/1 * * * * /Users/ABC/Desktop/exe.sh

cron restart
