我们正在使用 CommandLineJobRunner 来执行 Spring Batch 作业。我们在命令行上使用 -next:
java -Dlog4j.configuration=file:./prop/log4j.properties -Dlogfile=logfile_load_data -jar EtlLoadData.jar loaddata_etl_config.xml loaddata_etl_job -next
我们开始出现错误:
Job Terminated in error: A job instance already exists and is complete for parameters={run.id=10}. If you want to run this job again, change the parameters.
org.springframework.batch.core.repository.JobInstanceAlreadyCompleteException: A job instance already exists and is complete for parameters={run.id=10}. If you want to run this job again, change the parameters.

我认为如果您使用该-next
选项运行,这应该不是问题。有任何想法吗?
作为临时解决方法,我清理了数据库中的 SpringBatch 表,但我不希望这种情况再次发生。
