私はジョブコンテキスト（JobExecution）を使用して、プロセッサに巨大な定数データを渡します。ジョブが実行された後、Spring BatchはMeta-Dataテーブルに書き込みますが、SERIALIZED_CONTEXTはテーブルにとって大きすぎます。春バッチ - 'SERIALIZED_CONTEXT'列のデータが長すぎます
SERIALIZED_CONTEXTをメタテーブルに書き込むことをスキップする方法はありますか？または、メタテーブルに書き込む前にジョブのコンテキストをクリアする方法はありますか？
@Component
public class JobCompletionNotificationListener extends JobExecutionListenerSupport {
@Override
public void beforeJob(JobExecution jobExecution){
ExecutionContext jobContext = jobExecution.getExecutionContext();
jobContext.put("clientList", someHugeData);
}
}
