Aurora Mysql 5.7 LONG 类型的长度 (4) 无效

Question

我有一个使用 Hibernate 和 AWS Aurora Mysql 5.7 版本的 Spring Boot 应用程序。

我的存储库中有此查询：

    @Cacheable(cacheNames = "documents#chartprofitbyday")
    @Transactional(readOnly = true)
    @Query("SELECT new org.javatuples.Quartet(COALESCE(SUM(d.grossProfit),0),COALESCE(CAST(AVG(d.grossMargin) as big_decimal),0),MONTH(d.date),DAY(d.date)) FROM Document d WHERE d.type IN (:types) AND d.status<>'CANCELED' AND d.status<>'DECLINED' AND d.store.id=:storeId AND d.date>=:from AND d.date<=:until GROUP BY MONTH(d.date),DAY(d.date) ORDER BY MONTH(d.date),DAY(d.date)")
    List<Quartet<BigDecimal, BigDecimal, Integer, Integer>> chartProfitByDay(@Param("types") List<DocumentType> types, @Param("from") LocalDate from, @Param("until") LocalDate until, @Param("storeId") Long storeId);

有时（并非总是），我有这个例外：

我没有看到我的查询中哪里有长整型，grossProfit并且grossMargin在我的数据库中被声明为 DECIMAL(12,2) 。

您对如何理解和解决问题有什么建议吗？

Answer 1

您的storeId是 Long 类型。
@Param("storeId") Long storeId

List<Quartet<BigDecimal, BigDecimal, Integer, Integer>> chartProfitByDay(@Param("types") List<DocumentType> types, @Param("from") LocalDate from, @Param("until") LocalDate until, @Param("storeId") Long storeId);

我认为这个错误是因为你的storeId类型是 Long 并且你提供了 Integer。

List<Quartet<BigDecimal, BigDecimal, Integer, Long>>
