запланированные задания в пакетном приложении иногда выдают ошибку

Question

У меня есть планировщик, чтобы запланировать выполнение заданий в определенное время. Он содержит около 10 заданий, которые должны быть выполнены в соответствии с заданным выражением cron. Но иногда не удается выполнить некоторые задания, выдавая исключение «CannotSerializeTransactionException», и это происходит чаще всего.

У нас есть platformTransactionManager, который возвращается в jobRepository, который создается динамически.

@Bean(name = "jpaTransactionManager")
    @Primary
    public PlatformTransactionManager jpaTransactionManager() throws SQLException{
        return new JpaTransactionManager(this.entityManagerFactory().getObject());
    }

Итак, я не могу установить уровень изоляции для jobRepository. Как решить проблему сейчас, чтобы устранить ошибку. Я пытался разобраться в проблеме, но не мог понять, что вызывает сбой работы.

    public void dailyStatusEmailNotificationJobRun() throws JobExecutionAlreadyRunningException, JobRestartException, JobInstanceAlreadyCompleteException, JobParametersInvalidException{
        final JobParameters jobParameters = new JobParametersBuilder().addDate(START_TIME, new Date(System.currentTimeMillis())).toJobParameters();
        jobLauncher.run(dailyStatusEmailNotifyJob, jobParameters);

    }```

I expect the jobs should run correctly.

The error trace thrown is:
[batch] 05.07.2019 09:00:00.270 [OUT] [ERROR] [            ] [         ] org.springframework.scheduling.support.TaskUtils$LoggingErrorHandler Unexpected error occurred in scheduled task.
