Spring批处理非法状态（仅在竞争条件下发生）>；：作业执行已在运行

在我的Spring批处理应用程序中，我使用PostgreSQL作为作业存储库，并使用以下登录来重新启动未完成的作业：

try {
    jobRegistry.register(new ReferenceJobFactory(documetPipelineJob));

    List<String> jobs = jobExplorer.getJobNames();
    for (String job : jobs) {

    Set<JobExecution> jobExecutions = jobExplorer.findRunningJobExecutions(job);

    for (JobExecution jobExecution : jobExecutions) {

        jobExecution.setStatus(BatchStatus.STOPPED);
        jobExecution.setEndTime(new Date());
        jobRepository.update(jobExecution);

        Long jobExecutionId = jobExecution.getId();
        jobOperator.restart(jobExecutionId);
    }
    }
} catch (Exception e) {
    LOGGER.error(e.getMessage(), e);
}

试试看{
jobRegistry.register（新引用jobFactory（documetPipelineJob））；
List jobs=jobExplorer.getJobNames（）；
for（字符串作业：作业）{
设置jobExecutions=jobExplorer.findRunningJobExecutions（作业）；
for（作业执行作业执行：作业执行）{
jobExecution.setStatus（BatchStatus.STOPPED）；
jobExecution.setEndTime（新日期（））；
jobRepository.update（作业执行）；
Long jobExecutionId=jobExecution.getId（）；
jobOperator.restart（jobExecutionId）；
}
}
}捕获（例外e）{
LOGGER.error（e.getMessage（），e）；
}

但此逻辑失败，出现以下异常：

2018-08-01 14:33:21.777错误32306---[main] c、 v.p.d.service.batch.BatchServiceImpl:非法状态（仅发生 在竞争条件下）：作业执行已与一起运行 名称=documetPipelineJob和参数=

这里可能有什么问题，如何解决

看起来像

jobRepository.update（作业执行）不向数据库提交更改。如何正确提交对数据库的更改？顺便说一句-此逻辑在内存数据库中使用H2时运行良好。
为了解决此问题，我添加了
incrementer（new RunIdIncrementer（））
：

我还扩展了重启逻辑，以停止运行以下步骤：

try {
    jobRegistry.register(new ReferenceJobFactory(documetPipelineJob));

    List<String> jobs = jobExplorer.getJobNames();
    for (String job : jobs) {

    Set<JobExecution> jobExecutions = jobExplorer.findRunningJobExecutions(job);

    for (JobExecution jobExecution : jobExecutions) {

        Collection<StepExecution> stepExecutions = jobExecution.getStepExecutions();
        for (StepExecution stepExecution : stepExecutions) {
        BatchStatus status = stepExecution.getStatus();
        if (status.isRunning() || status == BatchStatus.STOPPING) {
            stepExecution.setStatus(BatchStatus.STOPPED);
            stepExecution.setEndTime(new Date());
            jobRepository.update(stepExecution);
        }
        }

        jobExecution.setStatus(BatchStatus.STOPPED);
        jobExecution.setEndTime(new Date());
        jobRepository.update(jobExecution);

        Long jobExecutionId = jobExecution.getId();

        jobOperator.restart(jobExecutionId);
    }
    }
} catch (Exception e) {
    LOGGER.error(e.getMessage(), e);
}

try {
    jobRegistry.register(new ReferenceJobFactory(documetPipelineJob));

    List<String> jobs = jobExplorer.getJobNames();
    for (String job : jobs) {

    Set<JobExecution> jobExecutions = jobExplorer.findRunningJobExecutions(job);

    for (JobExecution jobExecution : jobExecutions) {

        Collection<StepExecution> stepExecutions = jobExecution.getStepExecutions();
        for (StepExecution stepExecution : stepExecutions) {
        BatchStatus status = stepExecution.getStatus();
        if (status.isRunning() || status == BatchStatus.STOPPING) {
            stepExecution.setStatus(BatchStatus.STOPPED);
            stepExecution.setEndTime(new Date());
            jobRepository.update(stepExecution);
        }
        }

        jobExecution.setStatus(BatchStatus.STOPPED);
        jobExecution.setEndTime(new Date());
        jobRepository.update(jobExecution);

        Long jobExecutionId = jobExecution.getId();

        jobOperator.restart(jobExecutionId);
    }
    }
} catch (Exception e) {
    LOGGER.error(e.getMessage(), e);
}

@Override
protected JobRepository createJobRepository() throws Exception {
    JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
    factory.setDataSource(dataSource);
    factory.setTransactionManager(transactionManager);
    factory.setIsolationLevelForCreate("ISOLATION_READ_UNCOMMITTED");
    factory.afterPropertiesSet();
    return factory.getObject();
}
