春天的日期冬眠的查詢

我有一種方法從數據庫中獲取教育事件。不知道爲什麼它無法運行。看起來查詢僅在某些情況下失敗，但無法真正找出破壞它的輸入參數。我無法從日誌中獲得關於位置1853處的語法錯誤的任何提示。您是否有任何想法導致問題或如何進一步調試該方法？春天的日期冬眠的查詢

public List<EE> findEEs(S s, List<EM> eMs, E e) { 
    TypedQuery<EE> query = entityManager.createQuery(
     "select distinct ee from EE ee left join ee.lSE lse " 
      + "where ee.eM in (:em) " 
      + "and (ee.scope = :publicScope " 
      + "or (ee.scope = :limitedScope and (ee.hE= :e or :e in lse)) " 
      + "or (ee.scope = :localScope and ee.hE = :education)) " 
      + "and ee.status = :status and ee.startDate > :now " 
      + "and (ee.groupSize = 0 or (ee.groupSize > 0 " 
      + " and ee.groupSize > (ee.numberOfStudents + ee.reservedSeats))) " 
      + "and ee.id not in (select pee.eE.id from PEE pee " 
      + "where studentStatus.s = :s and eE.eM in (:em))", 
     EE.class); 

    query.setParameter("s", s); 
    query.setParameter("em", eMs); 
    query.setParameter("publicScope", PUBLIC); 
    query.setParameter("limitedScope", LIMITED); 
    query.setParameter("localScope", LOCAL); 
    query.setParameter("e", e); 
    query.setParameter("status", CONFIRMED); 
    query.setParameter("now", new DateTime()); 

    return query.getResultList();

日誌顯示這一點：

你確定你的'：em'參數永遠不是空的嗎？你正在使用什麼版本的休眠？它是'> ='3.6.1嗎？ –

請增加休眠日誌記錄（查詢+綁定參數）...爲一個失敗的....我懷疑joda（？）DateTime是責怪.. – xerx593

@AbdullahKhan，其實這是一個很好的觀點。：em參數確實有時是空的，但不應該查詢返回空結果列表而不是失敗？ – krltos

從逗號分隔的列表的docs

必須有至少一種元素限定用於IN的設定值的表達。

確保您傳入的參數至少有一個值。

也查看相關question。
