为 Spring Kafka 设置 authorizationExceptionRetryInterval

Question

任何人都知道如何设置新属性：authorizationExceptionRetryInterval，而无需手动创建 ConcurrentKafkaListenerContainerFactory。

Answer 1

我想说...

@Component
class ContainerFactoryCustomizer {

    ContainerFactoryCustomizer(AbstractKafkaListenerContainerFactory<?, ?, ?> factory) {
        factory.setContainerCustomizer(
                container -> container.getContainerProperties()
                        .setAuthorizationExceptionRetryInterval(Duration.ofSeconds(10L)));
    }

}

但这不起作用，due to a bug (the container customizer is not set up)。

这是一个解决方法：

@SpringBootApplication
public class So60054097Application {

    public static void main(String[] args) {
        SpringApplication.run(So60054097Application.class, args);
    }

    @KafkaListener(id = "so60054097", topics = "so60054097", autoStartup = "false")
    public void listen(String in) {
        System.out.println(in);
    }

    @Bean
    public NewTopic topic() {
        return TopicBuilder.name("so60054097").partitions(1).replicas(1).build();
    }


    @Bean
    public ApplicationRunner runner(KafkaListenerEndpointRegistry registry) {
        return args -> {
            MessageListenerContainer container = registry.getListenerContainer("so60054097");
            container.getContainerProperties()
                    .setAuthorizationExceptionRetryInterval(Duration.ofSeconds(10L));
            container.start();
        };
    }
}

（将autoStartup设置为false；修复属性并启动容器）。
