我试图从 Micronaut kafka 实现中获取非阻塞响应，但是返回值不起作用。
public class ProductManager implements IProductManager{
private final ApplicationContext applicationContext;
public ProductManager(ApplicationContext applicationContext) {
this.applicationContext = applicationContext;
}
@Override
public ProductViewModel findFreeText(String text) {
final ProductViewModel model = new ProductViewModel();
IProductProducer client = applicationContext.getBean(IProductProducer.class);
client.findFreeText(text).subscribe(item -> {
System.out.println(item);
});
return model;
}
}
订阅方法不起作用，调试器永远不会到达这一点。我想从 kafka 监听器获取值
卡夫卡制作人
@KafkaClient
public interface IProductProducer {
@Topic(ProductTopicConstants.GET_FREE_TEXT_SEARCH)
Flowable<ProductViewModel> findFreeText(String text);
}
卡夫卡监听器
@KafkaListener(offsetReset = OffsetReset.EARLIEST)
public class ProductListener {
private static final Logger LOG = LoggerFactory.getLogger(ProductListener.class);
@Topic(ProductTopicConstants.GET_FREE_TEXT_SEARCH)
public Flowable<Product>> findByFreeText(String text) {
LOG.info("Listening value = ", text);
return Flowable.just(new Product("This is the test", 0,"This is test description"));
}
}
