いつかこの問題が発生しています。春バッチ - ItemWriter - DataIntegrityViolationException - レコードをスキップ - 再試行 - 動作していません
私は3.0.7
問題がItemWriter内の1つのレコードにorg.springframework.dao.DataIntegrityViolationExceptionの場合で、スプリングバッチを使用しています、チャンク内のレコードの残りの部分（チャンクサイズ= 10）ですskipPolicy（すべての例外に対してtrueを返す）を提供した後でも、DBに挿入されません。
チャンク全体をコミットしている間にスキップされる例外（スキップされたもの）があれば、現在のトランザクションはロールバックされます。チャックサイズ（コミット間隔）は1にリセットされます。チャンクのレコードが個別に再試行されて問題のあるレコードが見つかると、そのレコードだけがDBに入りません。残りのレコードはDBに格納されます。
しかし、これは起こっていません。チャンクトランザクションはロールバックされますが、個々のレコードは再試行されません。
私は、skipPolicy（shouldSkipメソッド）とskipListener（onSkipInWriteメソッド）にデバッグポイントを置いていますが、フローはデバッグポイントに来ていません。
私は以下
（ライタから同じを呼び出す）DAO層はHibernateでCrudRepositoryを使用していますが、私のコードです：
/**
* @return processCRMRecords
*/
@Bean
public Step processCRMRecordsStep() {
return stepBuilderFactory.get("crm-sr-files-processing-step").<CRMSrRecord, SRRecordEO> chunk(10)
.reader(crmSrMultiFileReader(null, null)).processor(crmSrRecordProcessor()).writer(crmRecordWriter())
.faultTolerant().skipPolicy(skipSRPolicy()).listener(listener).build();
}
/**
* @return SkipPolicy
*/
@Bean
public SkipPolicy skipSRPolicy() {
return new RecordVerificationSkipper();
}
SkipPolicy：
public class RecordVerificationSkipper implements SkipPolicy {
Logger logger = LoggerFactory.getLogger(RecordVerificationSkipper.class);
/**
*
*/
public RecordVerificationSkipper() {
//
}
/* (non-Javadoc)
* @see org.springframework.batch.core.step.skip.SkipPolicy#shouldSkip(java.lang.Throwable, int)
*/
@Override
public boolean shouldSkip(Throwable t, int skipCount) {
return true;
}
}
SkipListener：
@Override
public void onSkipInWrite(S item, Throwable t) {
if (item instanceof IRecordString) {
logger.info(((IRecordString) item).getRecordAsString());
}
}
例外：
