Answer 1

You need to create the JsonValidator bean. You need to change yor SalecChannelEventProcessor to be:
#Component
#Slf4j
#RequiredArgsConstructor
public class SalecChannelEventProcessor {
private static final String MESSAGE_TYPE = "sales_channel_update";
#NonNull
private final ObjectMapper objectMapper;
#Bean
public JsonValidator jsonValidator(){
return new JsonValidator();
}
#SneakyThrows(JsonProcessingException.class)
public boolean isValid(EnvelopedMessage envelopedMessage) {
if (!MESSAGE_TYPE.equals(envelopedMessage.getType())) {
return false;
}
return jsonValidator().validate(envelopedMessage);
}
}
