I think you might confuse Job and CronJob. A Job is the task that should be done. A CronJob is a single execution of that task. So if you want to execute a Job, you have to create an instance of a CronJob. You define the task a CronJob should execute by selecting the right Job instance. When this CronJob is started, the perform method of the corresponding AbstractJobPerformable class is called with the CronJob as parameter.
So how do you create parameters for an execution? Create a subtype of the type CronJob and add all your needed parameters as attributes. When you then create the CronJob, set all attributes accordingly. In the perform method you can then access the attributes of that CronJob instance.
You create the CronJob like this:
HelloWorldCronJobModel cronJob = modelService.create(HelloWorldCronJobModel.class);
JobModel myJob = cronJobService.getJob("myJob");
cronJob.setJob(myJob);
// Add own attribute to Job
cronJob.setGreetedPerson("John Doe");
modelService.save(cronJob);
cronJobService.performCronJob(cronJob);
When your perform method is called, access the attribute:
#Override
public PerformResult perform(MyCronJobModel myCronJob) {
LOG.info("Hello " + myCronJob.getGreetedPerson());
return new PerformResult(CronJobResult.SUCCESS, CronJobStatus.FINISHED);
}
