У меня есть метод, который использует findById()
метод Spring Data JPA.Однако этот метод возвращает ClassCastException
в строке номер 1 метода getSupportedKey (), где я вызываю findById ():
MySupportedKey cannot be cast to java.util.Optional
private MySupportedKey getSupportedKey(String tenant, String key) {
Optional<MySupportedKey> mySupportedKeyOptional = mySupportedKeyRepository.findById(new MySupportedKeyId(tenant, key));
MySupportedKey mySupportedKey= null;
if(mySupportedKeyOptional !=null) {
mySupportedKey= mySupportedKeyOptional.orElse(null);
}
return mySupportedKey;
}
Я долго бился, но я неполучить что-нибудь.Пожалуйста, помогите мне в решении этой проблемы.Я использую spring-data-jpa: 2.0.8.RELEASE .
Добавление исходного кода репозитория:
public interface MySupportedKeyRepository extends JpaRepository<MySupportedKey, MySupportedKeyId> {
List<MySupportedKey> findByIdTenant(@NotNull String tenant);
}
Добавление полной трассировки стека ошибок:
