Question

我有以下SpringData存储库查询：

    @Query("SELECT new com.mypackage.MobileCaseList(c.ident, concat(c.subtype, ' - ', c.contactName), c.type, coalesce(c.updateTimestamp,c.insertTimestamp) )" +  
            "FROM MobileCase c WHERE c.mobileUser.ident = ?1 AND c.origin = 'SOURCE' ORDER BY c.appointmentFrom NULLS LAST") 
    List<MobileCaseList> findCasesForUser(String userIdent);

遵循运行时代码：

    List<MobileCaseList> result = caseRepo.findCasesForUser(userIdent);

直到现在这个工作正常 - 不知道是什么导致了例外。在我的电脑（localhost）上它仍然有用！？但是在Ubuntu服务器上，查询执行失败并出现以下错误：

任何想法，建议......？

Answer 1

正如@leonardoborges所写，这个问题was described as bug，应该从版本1.10.3开始修复。这里没有更多关于这个问题的补充。

Answer 2

您可以使用 nativequery=true

编写本机查询

QueryException：“select new”查询不允许使用ResultTransformer
