Hibernate 4和Postgres 9：Criteria.list（）拋出異常

我遇到了涉及postgres jdbc驅動程序版本9.1-901.jdbc3的奇怪問題。這裏是吾道Hibernate 4和Postgres 9：Criteria.list（）拋出異常

@Override 
    public List<Products> getProductsListByIds(List<String> ids, Integer storeId) { 
    Criteria criteria = getSession().createCriteria(Products.class) 
    .add(Restrictions.eq("storeId", storeId)) 
    .add(Restrictions.in("productId", ids)) 
    .add(Restrictions.isNotEmpty("createdAt")) 
    .add(Restrictions.isNotEmpty("updatedAt")) 
    .add(Restrictions.isNotNull("id")) 
    return criteria.list(); 
    }

當我運行SQL語句返回96分的結果和我猜的100 Hibernate有固定列表大小（即我多少IDS通過限制），並返回在4個空對象名單。作爲結果的Postgres JDBC驅動程序時，它試圖映射空到時間戳與下面的異常失敗：

有沒有辦法告訴Hibernate只加載導致它變得不填充空值的元素休息？

Hibernate沒有固定的列表大小，它只是執行查詢。它不能將行值轉換爲時間戳。可能是行有日期類型。當我在數據庫中設置了非空限制之後，當行包含零值（00/00/00 ...）時，我在mysql中出現了類似的錯誤。

我不知道是怎麼回事上，但看起來像是司機的問題。我更新到9.2版，但仍然出現錯誤。當我運行簡單選擇它返回數據罰款。所以只是爲了它，我已經將列從非null更改爲null，然後將created_at設置爲null。一切都很順利。然後我使用to_timestamp函數更新了created_at。它開始再次失敗。我完全迷失在這裏。 – Mike

我不認爲isNotEmpty是像createdAt這樣的時間戳字段的有效限制。

根據文檔，它僅適用於收集財產。

約束集合值屬性爲非空

你應該在這裏使用isNotNull。

public List<Products> getProductsListByIds(List<String> ids, Integer storeId) { 
    Criteria criteria = getSession().createCriteria(Products.class) 
     .add(Restrictions.eq("storeId", storeId)) 
     .add(Restrictions.in("productId", ids)) 
     .add(Restrictions.isNotNull("createdAt")) 
     .add(Restrictions.isNotNull("updatedAt")) 
     .add(Restrictions.isNotNull("id")) 
    return criteria.list(); 
}

另一個側面說明：Postgres的驅動程序9.1.901似乎有些系列的性能問題，我建議移動到9.1.902最新版本或9.1.903
