I have been trying to use Spring Data Redis but it fails for queries with List in them and just won't work. I tested it with normal fields such as ID and it works fine without issues, would appreciate it if someone can look at my code, thanks!
I have the following model:
@RedisHash("Flight")@Data@NoArgsConstructor@AllArgsConstructorpublic class Flight implements Serializable { @Id private String id; @Indexed private List<String> dayOfWeek;}But when I try to define a query in my repository as follows:
@Repositorypublic interface FlightRepository extends CrudRepository<Flight, String> { List<Flight> findFlightsByDayOfWeek(List<String> dayOfWeek);}It throws the following exception when called:
Exception in thread "main" org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [byte] for value 'Monday'; nested exception is
