트랜잭션 메소드가 서로 호출되지만 커밋해야하는 트랜잭션이 커밋되거나 적어도 삽입 로그가 커밋 된 것처럼 보입니다. 여기에 통화 hierachy은 다음과 같습니다Spring Propagation.REQUIRES_NEW @ 트랜잭션 트랜잭션 종료 후 로그에 트랜잭션 커밋이 나타납니다.

것은 만 내가 ENTITY_CHANGED_IN_REVISION 테이블의 로그에 삽입을받을 루트/초기 메소드 호출/EntityChange 엔티티의 반환 후 :
이 시점 :
@Override
@Transactional
public DataProcessingStatistics copyInitialRevision() {
try {
DataProcessingStatistics statistics = new DataProcessingStatistics();
transaction(statistics);
statistics.printResult();
return statistics; // only after that return insert log appear
} catch (Exception e) {
e.printStackTrace();
throw new RuntimeException(e);
}
}
이 로그는 반환 후에 나타납니다

Hibernate: insert into ENTITY_CHANGED_IN_REVISION (ENTITY_ID, ENTITY_NAME, GROUP_ENTITY_ID, GROUP_NAME, REV_ID, REVISION_TYPE, ID) values (?, ?, ?, ?, ?, ?, ?)

대신 "500 행 덩어리를 저장"방법에서 복귀 한 후이를 reveiving의 @Transactional입니다 (전파 = Propagation.REQUIRES_NEW) :
@Override
@Transactional(propagation=Propagation.REQUIRES_NEW)
public <E> void save500(final List<E> rows, ListSaver<E> saver) {
if (rows == null || rows.size() == 0) {
return;
}
if (rows.size() > 500) {
throw new IllegalStateException("(auditTableRows.size() > 500)");
}
saver.save(rows); // invokes EntityChangeServiceImpl.saveFromRow
}
...
@Service
public class EntityChangeServiceImpl implements EntityChangeService {
@Override
@Transactional
public void saveFromRow(EntityAuditTableRow auditTableRow) {
Revision revision = revisionsService.load(auditTableRow.getAuditTableRow().getRevision().getId());
EntityChange entityChange = create(auditTableRow);
save(entityChange);
revision.getEntitiesChanges().add(entityChange);
revisionsService.save(revision);
}
