我想使用这个扩展：[Quarkus Smallrye响应式消息传递Kafka]
但在我的应用程序中，主题的名称是事先不知道的，它是根据运行时从用户那里收到的消息指定的。如何在没有注解的情况下以编程方式指定主题名称和与主题相关的设置？（仅用于向Kafka -> Produce发送消息）

@ApplicationScoped
public class PriceGenerator {

    private Random random = new Random();

    // Don't want to use this 
    // "generated-price" not known at build time
    @Outgoing("generated-price")                       
    public Multi<Integer> generate() {                  
        return Multi.createFrom().ticks().every(Duration.ofSeconds(5))
                .onOverflow().drop()
                .map(tick -> random.nextInt(100));
    }

}

或者，应在运行时以编程方式设置这些参数

mp.messaging.outgoing.generated-price.connector=smallrye-kafka
mp.messaging.outgoing.generated-price.topic=prices
mp.messaging.outgoing.generated-price.value.serializer=org.apache.kafka.common.serialization.IntegerSerializer

因为我不认识路，所以我使用了原生的Kafka驱动程序
