我已經在我的存盤庫中定義了這個函式，當我測驗它并且所有欄位都包含值時，它在我的資料庫中運行良好。
@Query(value="SELECT employee_id,\n"
"SUM(january) as january,SUM(february) as february, SUM(march) as march, SUM(april) as april, SUM(may) as may, SUM(june) as june, SUM(july) as july, SUM(august) as august, sum(september) as septebmer, sum(october) as october, sum(november)as november\n"

但是，當我嘗試通過控制器回傳結果時，它會回傳一些空欄位（ december 和 september ）
this is the result in my database :
id jan feb ................................december
14 21 20 23 22 22 22 21 23 22 21 22
15 21 20 1 0 0 0 0 0 0 0 0
16 21 20 23 21 5 22 21 23 22 21 22
17 21 20 1 0 0 0 0 0 0 0 0
18 10 0 0 0 0 0 0 0 0 0 0
19 21 20 23 21 22 22 21 23 22 21 22
20 0 0 23 21 22 22 21 23 22 0 0
21 0 0 0 21 22 22 21 23 22 21 22
22 0 0 23 21 22 22 21 23 22 21 22
23 0 0 23 21 22 22 21 23 22 21 22
這是 POSTMAN 中的回應 JSON：

最后：這是我的 WorkdaysRepartition 界面
public interface WorkdaysRepartition {
Long getEmployee_id();
Long getJanuary();
Long getFebruary();
Long getMarch();
Long getApril();
Long getMay();
Long getJune();
Long getJuly();
Long getAugust();
Long getSeptember();
Long getOctober();
Long getNovember();
Long getDecember();
}
任何解決方案？
