在调试我的服务器端代码时,我意识到我的删除行不起作用。我刚刚从我的插入中复制了这段代码,并将 session.saveORUpdate 替换为 session.delete。删除对象是否正确?我在这里做错了什么?

我没有任何例外。

public void delete(Object dataStore) throws DidNotSaveRequestSomeRandomError {
    Transaction txD;
    Session session;
    session = currentSession();

    //get first and then fallback to begin.
    if (session.getTransaction() != null
            && session.getTransaction().isActive()) {
        txD = session.getTransaction();
    } else {
        txD = session.beginTransaction();
    }

    try {
        session.delete(dataStore);
    } catch (MappingException e) {
        e.printStackTrace() ;
    }
    try {
        txD.commit();
        while (!txD.wasCommitted())
            ;
    } catch (ConstraintViolationException e) {
        log.error("Unable to delete data from "
                + dataStore.getClass().toString());
        txD.rollback();
        throw new DidNotSaveRequestSomeRandomError(dataStore,
                feedbackManager);
    } catch (TransactionException e) {
        log.debug("txD state isActive" + txD.isActive()
                + " txD is participating" + txD.isParticipating());
        log.debug(e);
        txD.rollback();
    } finally {
        session.flush();
        txD = null;
        session.close();
    }
}

编辑 :

我尝试将 session.flush 放在 session.delete 之后,但没有用。
