CronExpression replaces CronSequenceGenerator, which is based on and which has several known issues that none of the Spring team members felt comfortable solving. Then call the afterProperties method of ScheduledTaskRegistrar to schedule the task with new cron expressions. In Spring 5.3, we introduced the CronExpression class, which represents you guessed it a cron expression. Batch Stereotypes While the Job object may seem like a simple container for steps, you must be aware of many configuration options. If there is a change in the cron expression, it will stop all the scheduled task and rerun the configureTasks(ScheduledTaskRegistrar scheduledTaskRegistrar) concurrently again for each of the new cron expression. Configuring and Running a Job XML Java Both In the domain section, the overall architecture design was discussed, using the following diagram as a guide: Figure 1. Here the configureTasks will be called during the bootstrap only, but how do we do that now by stopping the existing triggers and creating new trigger task with new cron expressions?įirst I will maintain a database property where I will have the cron expression separated by the pipe symbol so that I can change the cron expression on the fly without changing the server.ĭuring the every trigger time I will check the cron expression modified by pulling the cron from data base. Now, to change the task to run at every 2, 7, or 9 minutes all the time and the stop the triggers added for evey 1, 5, or 10 minutes but without having to restart my server.
