如何在 Java 中格式化来自 Mysql 数据库的日期

Question

我有一个方法可以返回在特定日期内进行的交易。问题是我的项目要求我应该以一种也接受时间的格式提供开始和结束日期，但这不是我想要的，因为客户会发现输入时间也不友好。当我将信息保存到数据库中时，我没有及时保存它。我只保存了日期，这就是我在数据库中看到的，但我不知道为什么系统只有在我提供这种格式的东西时才能工作 “结束日期”：“2023-03-30T00：20：27.177Z”， “开始日期”：“2023-03-30T00:20:27.177Z” 但我需要的是这种格式的东西 "endDate": "yyyy-MM-dd", “开始日期”：“yyyy-MM-dd”

What I meant is if I used LocalDate instead of Date, will I be able to do this query?

@Query("select t from TransactionType t where t.transactionDate >= :startDate and t.transactionDate <= :endDate")
    List<TransactionType> getTransactionStatement(@Param("startDate") Date startDate, @Param("endDate") Date endDate
