Question

我在开发Spring Batch时正在学习。要求是;如果我必须在处理过程中终止该过程；批次应该可以从停下来的地方取货。批处理基于日期范围和处理从数据库表中读取数据并在处理完后写入另一个表。

我已将作业标记为restartable = true。出于测试目的，当我在本地完全杀死工作（流程）时。我使用下面的sql将job_execution_id和step_execution_id的状态更新为“ FAILED”

update batch_job_execution
set status = 'FAILED'
where job_execution_id = '226'

update batch_step_execution
set status = 'FAILED'
where step_execution_id = 1357

其中批处理作业的最后一个作业执行ID为226，作业实例ID为198，其对应的步骤执行为1357

但是工作仍然低于

org.springframework.batch.core.launch.support.SimpleJobLauncher.java line number 131

jobExecution = jobRepository.createJobExecution(job.getName(), jobParameters);

Exception thrown 

org.springframework.batch.core.repository.JobExecutionAlreadyRunningException: A job execution for this job is already running: JobInstance: id=198, version=0, Job=[XYZ]

尝试使我的春季批处理作业可重新启动
