일괄 처리 프로그램이 LazyInitializationException 예외를 발생시킵니다. 이것은 매번 발생하지 않습니다. 거의 발생하지 않으며 배치를 다시 실행하면 레코드가 오류없이 처리됩니다.org.hibernate.LazyInitializationException : 프록시를 초기화 할 수 없음 - 세션 없음 - 드물게 발생 함
는 I는 I 레코드의 실제 수보다 큰 수로 (100)로부터 플러시 레코드의 수를 증가하면 다음 코드
private void flushHibernateCache() {
final String CM_FLUSH_HBM_CHACHE = "flushHibernateCache";
final String CM_CLEAR_HBM_CHACHE = "clearHibernateCache";
BigInteger sessionLimit = getParameters().getSESSION_FLUSH_LIMIT();
if (notNull(sessionLimit) && recordsProcessed.mod(sessionLimit).intValue() == 0) {
FrameworkSession session = (FrameworkSession) SessionHolder.getSession();
session.flush(CM_FLUSH_HBM_CHACHE);
session.clear(CM_CLEAR_HBM_CHACHE);
}
}
을 사용하여 처리 된 모든 100 개 개의 레코드에 대한 캐시 플러시있어 처리하려면 오류없이 일괄 처리가 실행됩니다.
