Java 以不同方式管理的调试模式事务

我想从带有特定sql语句的列表中删除对象。 示例：包含消息列表的档案

我希望删除邮件后，列表会自动刷新。情况确实如此，但当我使用远程Java应用程序启动应用程序时，我必须使用实体管理器手动刷新档案。我想知道为什么在调试代码时会有这样的差异

我使用weblogic作为应用服务器

谢谢

BenefitDossier dossier = dossierRepo.getDossierByDossierId(dossierIdentifier, CREATED);

// perform the removing
messageRepository.removeOrUpdateMessagesFromDossier(dossier.getDossierId(), COMPLETENESS_RECOGNITION);

dossierRepo.refresh(dossier); // need to add this statement only in debug mode

return dossier;


@PersistenceContext(unitName = "dmb-jta")
protected EntityManager em;

public void removeOrUpdateMessagesFromDossier(DisBenMessageCategory category, String dossierNr) {
    if (category.preserveHistory()) {
        updateMessagesRemovalTimestamp(category, dossierNr);
    } else {
        removeMessages(category, dossierNr);
    }
}

private void removeMessages(DisBenMessageCategory category, String dossierNr) {
    StringBuilder updateStmt = new StringBuilder();
    updateStmt.append("DELETE FROM DisBenMessage msg ");
    updateStmt.append("WHERE msg.benefitDossier.dossierId = :dossierNr ");
    updateStmt.append("AND msg.category = :category ");

    Query query = em.createQuery(updateStmt.toString());
    query.setParameter("dossierNr", dossierNr);
    query.setParameter("category", category);

    int updateCount = query.executeUpdate();
    LOG.debug("Deleted " + updateCount + " messages.");
}

你能完全分享你的代码吗？这段代码很难说什么。希望它能帮助理解，谢谢。如果你禁用所有断点，这种情况还会发生吗？@farrellmr确实，当我禁用断点时，档案会很好地刷新。当应用程序服务器必须在断点处停止太长时间时，会丢失一些东西吗？交易失败？EntityManager不刷新？谢谢你，我认为这是一个时间问题——对于调试器来说，事务发生得太快了
