1. Write a class that handles timed tasks:@Repository Public class Quartzscore { publicvoid Runscore () { System.out.println ("timed task is executing ... "); System.out.println ("Current time:" +new SimpleDateFormat ("yyyy mm month DD Day HH:MM:SS"). Format (new Date ()));} }2.

IntroductionA timed task (cron Job) is used to schedule commands that need to be executed periodically. With it, you can configure certain commands or scripts to run periodically over a set period of time. Cron is one of the most useful tools in Linux or Unix-like systems. The Cron Service (daemon) runs in the background of the system and continuously checks the/etc/crontab file and the/etc/cron.*/directory. It will also check the/var/spool/cron/direc

Linux timed Execution Task command overview: at and crontabThere are two ways to implement tasks on a regular basis under Linux: at command and Crontab. If we just want to have a specific task run once, you can use the at Monitor program, and if it's an unattended operation, you can use the Cron service.This article describes two methods for performing tasks under Linux: At command, and the crontab service.(1) at commandIf we just want to have a speci

specified in the hh:mm (hour: minute) of the day. If the time has passed, then it will be executed the next day. Of course, you can use Midnight (late night), noon (noon), Teatime (tea time, usually 4 o'clock in the afternoon) and other vague words to specify the time. The user is also able to use the 12-hour timekeeping system, which is either a AM (morning) or PM (afternoon) After the time to indicate whether it is morning or afternoon. You can also specify a specific date for the execution o

Original address: http://blog.chinaunix.net/uid-7552018-id-182133.htmlToday I made a backup script of the database, and by the way the system had to learn the settings of the timed execution script under Linux. Linux scheduled execution is mainly used in the crontab file to add a custom plan to execute, the setup is slightly more complicated than Windows (because there is no graphical interface), but it is not very complex, basically used once to reme

Accustomed to scheduling tasks using Windows, it is not appropriate to use crontab in Linux to manage timed Tasks . So the basic usage is summarized as follows.Create a simple scheduled taskOutput the current time per minute and output to the Time.log file in the user's home directory.'date' >>/home/xxx/time. LogThe path to the Crontab program is/usr/bin/crontab.The scheduled tasks for each user can be queried in the/var/spool/cron/crontabs/dir
