Question

您知道如何将此属性（Calendar数组）传递给@NamedNativeQuery吗？

'[“1996-01-01 12:00:00”，“1996-01-01 17:00:00”]'

我尝试了以下方式但不起作用。

@NamedNativeQuery(
      name = "BusinessHours.deleteBusinessHours",
      query = "delete from business_hours " +
              "where company_address_id = ?1 and " +
              "hours = [?2,?3]"
)

编辑： postgres中的原生查询是：

DELETE FROM business_hours 
WHERE company_address_id = 7 
AND hours = '["1996-01-01 18:15:00","1996-01-01 18:30:00"]'

据我从删除语句中了解到，business_hours.hours被输入为DB中的一个字符。所以你需要的是将数组序列化为符合数据库预期格式的String，然后通过单个占位符传递该String：

query = "delete from business_hours where company_address_id = ?1 and hours = ?2"
