HQL中的java.lang.NullPointerException查詢

我有一個HQL查詢，我通過傳遞一個列表來檢查某些細節！確切的數組列表。下面是HQL查詢。HQL中的java.lang.NullPointerException查詢

<prop key="GET_HOTEL_TAX_RECORDS"> 
<![CDATA[ 
    select 
     HotelLevelTax 
    from HotelLevelTax ht 
    left join ht.hotel as h 
    left join ht.tax as t 
    where h.id in (:hotelId) and t.id in (:taxId) order by ht.id 
]]> 
</prop>

下面是我用來傳輸兩個參數數組列表的代碼。

if(searchCriteria.getHotel().getId() != null && searchCriteria.getTax().getId() != null){ 
    params.put("hotelId", searchCriteria.getHotel().getId()); 
    params.put("taxId", searchCriteria.getTax().getId()); 
}else{ 
    params.put("hotelId", hotels); 
    params.put("taxId", tax); 
} 

Query k = queryManager.getQuery(GET_HOTEL_TAX_RECORDS, params, em);

我從給定參數的getQuery行中得到一個空指針異常！在第一次運行時，searchCriteria參數爲null，所以else會被執行！我找不到在這裏發生nullpointer異常！

謝謝。

這是我的堆棧跟蹤！
