我的本机 Sql 查询正在工作，但 Hql 没有工作

Question

我正在使用休眠。我有一个清单。我在 dao 层上使用了 hql。但我的名单不存在。但我打开了 show_sql=true。然后本机sql正在工作。为什么我的原生 sql 能用，hql 不能用。

休眠查询

customers = entityManager.createQuery(
                    "SELECT c FROM LoungeCustomerCash c where c.operationDate between :beginDate and :endDate and c.boardingPass.operatingCarrierDesignator= :iataCode ORDER BY c.operationDate DESC")
                    .setParameter("iataCode", iataCode).setParameter("beginDate", beginDate)
                    .setParameter("endDate", endDate).getResultList();

原生 Sql 查询：

select loungecust0_.id as id2_59_, loungecust0_.CREATEDATE as CREATEDATE3_59_, loungecust0_.CREATEUSER as CREATEUSER4_59_, loungecust0_.UPDATEDATE as UPDATEDATE5_59_, loungecust0_.UPDATEUSER as UPDATEUSER6_59_, loungecust0_.VERSION as VERSION7_59_, loungecust0_.BOARDINGPASSID as BOARDINGPASSID14_59_, loungecust0_.customerType as customerType8_59_, loungecust0_.fullName as fullName9_59_, loungecust0_.LOUNGESERVICEID as LOUNGESERVICEID15_59_, loungecust0_.operationDate as operationDate10_59_, loungecust0_.price as price11_59_, loungecust0_.bankName as bankName12_59_ from LNCUSTOMER loungecust0_ cross join LNBOARDINGPASS boardingpa1_ where loungecust0_.service_type='CASH' and loungecust0_.BOARDINGPASSID=boardingpa1_.id and (loungecust0_.operationDate between to_timestamp('23/09/2018 11:09:02,660000000','DD/MM/RRRR HH24:MI:SSXFF')  and to_timestamp('23/12/2018 11:09:02,660000000','DD/MM/RRRR HH24:MI:SSXFF') ) and boardingpa1_.operatingCarrierDesignator='LH' order by loungecust0_.operationDate DESC

Answer 1

尝试使用接受结果类作为第二个参数的重载 createQuery 方法：

List<Customer> customers = entityManager.createQuery("...query ...", Customer.class)
            // set parameters
            .getResultList();
