Question

I am using spring batch to parse files and I have the following scenario:

I am running a job. This job has to parse a giving file. For unexpected reason (let say for pow

Answer 1

An updated work-around for Spring batch 4. Takes JVM start up time into account for broken jobs detection. Please note that this will not work when in a clustered environment where multiple servers start jobs.

@Bean
public ApplicationListener resumeJobsListener(JobOperator jobOperator, JobRepository jobRepository,
        JobExplorer jobExplorer) {
    // restart jobs that failed due to
    return event -> {
        Date jvmStartTime = new Date(ManagementFactory.getRuntimeMXBean().getStartTime());

        // for each job
        for (String jobName : jobExplorer.getJobNames()) {
            // get latest job instance
            for (JobInstance instance : jobExplorer.getJobInstances(jobName, 0, 1)) {
                // for each of the executions
                for (JobExecution execution : jobExplorer.getJobExecutions(instance)) {
                    if (execution.getStatus().equals(BatchStatus.STARTED) && execution.getCreateTime().before(jvmStartTime)) {
                        // this job is broken and must be restarted
                        execution.setEndTime(new Date());
                        execution.setStatus(BatchStatus.FAILED);
                        execution.setExitStatus(ExitStatus.FAILED);

                        for (StepExecution se : execution.getStepExecutions()) {
                            if (se.getStatus().equals(BatchStatus.STARTED)) {
                                se.setEndTime(new Date());
                                se.setStatus(BatchStatus.FAILED);
                                se.setExitStatus(ExitStatus.FAILED);
                                jobRepository.update(se);
                            }
                        }

                        jobRepository.update(execution);
                        try {
                            jobOperator.restart(execution.getId());
                        }
                        catch (JobExecutionException e) {
                            LOG.warn("Couldn't resume job execution {}", execution, e);
                        }
                    }
                }
            }
        }
    };
