Spring Data JPA @Query ArrayList as @Param

您好我有以下问题，我需要在JpaRepository中编写一个@Query，它将返回事务列表。我当前的查询如下所示：

@Query("SELECT t FROM Transaction t WHERE t.property IN :property AND (t.createdAt BETWEEN :dateFrom AND :dateTo) GROUP BY t.transactionType")
    List<Transaction> getAllByPropertyAndDatesBetweenGroupedByTransactionType(@Param("property")List<Property> property, @Param("dateFrom") Date dateFrom, @Param("dateTo") Date dateTo);

此处传递的所有参数均有效，但我收到错误：

"exception": "org.springframework.dao.InvalidDataAccessResourceUsageException",
    "message": "could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet",

当我正确指定所有内容时，为什么会出现此错误？

2 个答案:

答案 0 :(得分：0)

在这里，在您的查询中，您将传递Array List作为一个无法生成的参数，因为ArrayList可以包含重复数据。所以我更喜欢Set而不是ArrayList，你可以使用param的oreder数而不是@Param注释。

@Query("SELECT t FROM Transaction t WHERE t.property IN (?1) AND t.createdAt BETWEEN ?2 AND ?3 GROUP BY t.transactionType")
List<Transaction> getAllByPropertyAndDatesBetweenGroupedByTransactionType(Set<Property> property, Date dateFrom, Date dateTo);

答案 1 :(得分：0)

当您编写自定义SQL查询以从存储库获取结果时，它将返回List array而不是Object的{​​{1}}。< / p>

因此，在您使用List<YourClass/Entity>方法的情况下，方法的返回类型将为getAllByPropertyAndDatesBetweenGroupedByTransactionType()而不是List<Object[]>。

然后，您可以迭代List<Transaction>并根据需要处理每个元素。
