我正在使用React JS，并且已经从Material UI导入了一个名为（https://material-ui.com/api/table-pagination/）的组件，我想修改labelDisplayedRows的默认值，现在就像这个：

({ from, to, count }) => ${from}-${to} of ${count}

我想编辑输出的“ of”，但这是一个函数，所以我不知道该怎么做。如果它是一个像labelRowsPerPage这样的简单节点，我将通过编写来修改它

<TablePagination
                    labelRowsPerPage="text text text"
/>

我该怎么办？先感谢您

我正在尝试从 H2 db 表中获取一些值。做我需要的查询是这样的：

SELECT cast(creationDate as date) as DATE, SUM(paymentValue) as TOTAL,fxRate 
FROM payment 
group by DATE

其中“creationDate”、“paymentValue”、“fxRate”是“payment”表的列。CreationDate 是一个时间戳，所以我只需要从中获取日期。当我尝试用 Java 编写它时

 @Query("SELECT cast(creationDate as date) as daydate , SUM(paymentValue) as value1, fxRate as value2 FROM payment " + 
            "group by cast(creationDate as date)")
    List<Payment> findPaymentValuePerDay ();

我收到错误 [Ljava.lang.Object; cannot be cast to ...entity.Payment.

我还尝试使用一个名为 GraphDto 的不同对象，它具有属性 daydate、value1 和 value2

@Query("SELECT cast(creationDate as date) as daydate , SUM(paymentValue) as value1, fxRate as value2 FROM payment " + 
            "group by cast(creationDate …
