How-To: Defining a Job (with input data)

A Job Class

   
public class PrintPropsJob implements Job {

	public PrintPropsJob() {
		// Instances of Job must have a public no-argument constructor.
	}

	public void execute(JobExecutionContext context)
			throws JobExecutionException {

		JobDataMap data = context.getMergedJobDataMap();
		System.out.println("someProp = " + data.getString("someProp"));
	}

}

Defining a Job Instance

   
// Define job instance
JobDetail job1 = JobBuilder.newJob(MyJobClass.class)
    .withIdentity("job1", "group1")
    .usingJobData("someProp", "someValue")
    .build();

Also note that if your Job class contains setter methods that match your JobDataMap keys (e.g. “setSomeProp” for the data in the above example), and you use the default JobFactory implementation, then Quartz will automatically call the setter method with the JobDataMap value, and there is no need to have code in the Job’s execute method that retrieves the value from the JobDataMap.
