Am citit stabilit pe baza consistenta de validare blog și vreau să valideze printr-un dispecerat de interceptare. Am urmat exemplul, dar eu folosesc reactive depozit și nu funcționează pentru mine. Am încercat atât de bloc si nu se blocheaza. cu bloc se aruncă eroare, dar fără bloc nu executa nimic. aici este codul meu.
class SubnetCommandInterceptor : MessageDispatchInterceptor<CommandMessage<*>> {
@Autowired
private lateinit var privateNetworkRepository: PrivateNetworkRepository
override fun handle(messages: List<CommandMessage<*>?>): BiFunction<Int, CommandMessage<*>, CommandMessage<*>> {
return BiFunction<Int, CommandMessage<*>, CommandMessage<*>> { index: Int?, command: CommandMessage<*> ->
if (CreateSubnetCommand::class.simpleName == (command.payloadType.simpleName)){
val interceptCommand = command.payload as CreateSubnetCommand
privateNetworkRepository
.findById(interceptCommand.privateNetworkId)
// ..some validation logic here ex.
// .filter { network -> network.isSubnetOverlap() }
.switchIfEmpty(Mono.error(IllegalArgumentException("Requested subnet is overlap with the previous subnet.")))
// .block() also doesn't work here it throws error
// block()/blockFirst()/blockLast() are blocking, which is not supported in thread reactor-
