This article is about how Springboot implements scheduled tasks. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Scheduled task

The timing here is marked in the method + comments, if you want to modify the time of the generation environment, it is not very flexible, later add Quartz+boot, using the principle of database configuration and reflection.

Note: the cron expression of java is not quite the same as that of Linux. Note that java is 6 bits and linux is 5 bits.

Startup class

@ SpringBootApplication@EnableSchedulingpublic class Oss6Application {public static void main (String [] args) {SpringApplication.run (Oss6Application.class, args);}}

Service class

@ Servicepublic class ScheduledService {/ * second (seconds), minute (minutes), hour (hours), day of month (day), month (month), day of week (day of the week). * 0 * MON-FRI * [00 MON-FRI *] 5 14 minutes 18 * *?] every day at 14:00 sharp, and 18:00 sharp Every 5 minutes * [0 15 10? * 1-6] every month from Monday to Saturday at 10:15 * [0 02? * 6L] at 2 am on the last Saturday of every month * [0 02 LW *?] at 2 am on the last working day of each month * [0 02-4? * " 1] between 2: 00 a.m. and 4: 00 a.m. on the first Monday of every month Execute every hour on the hour. * / / @ Scheduled (cron = "0 * MON-SAT") / / @ Scheduled (cron = "0meme 1meme 2jue 3" 4 * MON-SAT ") / / @ Scheduled (cron =" 0-4 * MON-SAT ") @ Scheduled (cron =" 0amp 4 * MON-SAT ") / / execute public void hello () {System.out.println (" hello... ") every 4 seconds. Thank you for your reading! This is the end of this article on "how to achieve scheduled tasks in Springboot".
