请帮助我为什么我无法从数据库中获取数据。

在这里，我试图将数据从控制器传递到存储库，以便从数据库中获取数据，但是在获取数据时，它显示了一个错误，即使在实体类中实现了序列化之后也无法反序列化

Answer 1

您需要使用整个查询，而不仅仅是from和where子句：

@Query(value = "SELECT * from Flight where departureCity= :departureCity and arrivalCity= :arrivalCity and dateOfDeparture= :dateOfDeparture",nativeQuery = true)
// Here --------^

Answer 2

它将起作用

@Query(value = "SELECT * from Flight where departureCity= :departureCity and arrivalCity= :arrivalCity and dateOfDeparture= :dateOfDeparture",nativeQuery = true)
List<Flight> findFlights(@Param("departureCity") String from,@Param("arrivalCity") String to,@Param("dateOfDeparture") Date departureDate);

我的想法是，如果我们使用列名驼峰式大小写，则数据库列应在下划线下，例如如果我们使用arrivalCity，则 数据库基础列arrival_city。因此，请也以这种方式检查。

 @Query(value = "SELECT * from Flight where departure_city= :departureCity and arrival_city= :arrivalCity and date_of_departure= :dateOfDeparture",nativeQuery = true)
List<Flight> findFlights(@Param("departureCity") String from,@Param("arrivalCity") String to,@Param("dateOfDeparture") Date departureDate);

Answer 3

@Query(value ="SELECT * from Flight  where DEPARTURE_CITY=:departureCity and ARRIVAL_CITY=:arrivalCity and DATE_OF_DEPARTURE=:dateOfDeparture", nativeQuery = true)
    List<Flight> findFlights(@Param("departureCity") String from, @Param("arrivalCity") String to,@Param("dateOfDeparture") Date departureDate);

一旦尝试
