JobExecutionResult process(Job job, JobExecutionContext context)
JobExecutionContext.result().succeeded()If the job has not been processed completely, but might be rescheduled "failed" should be returned. This result can be generated by calling
JobExecutionContext.result().failed(). If the job processing failed and should not be rescheduled, "cancelled" should be returned. This result can be generated by calling
JobExecutionContext.result().cancelled(). If the executor decides to process the job asynchronously it should return
nulland notify the job manager by using the
JobExecutionContext.asyncProcessingFinished(JobExecutionResult)method of the processing result. If the processing fails with throwing an exception/throwable, the process will not be rescheduled and treated like the method would have returned a "cancelled" result. Additional information can be added to the result by using the builder pattern available from
job- The job
context- The execution context.
