我正在尝试使用Spring Cloud Stream和Kafka集成创建Spring Boot应用程序 . 我在Kafka中创建了一个带有1个分区的示例主题,并根据此处给出的指示从Spring Boot应用程序发布了该主题

http://docs.spring.io/spring-cloud-stream/docs/1.0.2.RELEASE/reference/htmlsingle/index.html

https://blog.codecentric.de/en/2016/04/event-driven-microservices-spring-cloud-stream/

Spring Boot App -

@SpringBootApplication
public class MyApplication {

    private static final Log logger = LogFactory.getLog(MyApplication.class);

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

Kafka 制片人班

@Service
@EnableBinding(Source.class)
public class MyProducer {

    private static final Log logger = LogFactory.getLog(MyProducer.class);

    @Bean
    @InboundChannelAdapter(value = Source.OUTPUT, poller = @Poller(fixedDelay = "10000", maxMessagesPerPoll = "1"))
    public MessageSource<TimeInfo> timerMessageSource() {
        TimeInfo t = new TimeInfo(new Timestamp(new Date().getTime())+"","Label");
        MessageBuilder<TimeInfo> m = MessageBuilder.withPayload(t);
        return () -> m.build();
    }

    public static class TimeInfo{

        private String time;
        private String label;

        public TimeInfo(String time, String label) {
            super();
            this.time = time;
            this.label = label;
        }

        public String getTime() {
            return time;
        }

        public String getLabel() {
            return label;
        }

    }
}

一切都运行良好,除非我想处理异常 .

如果Kafka主题发生故障,我可以看到在应用程序的日志文件中抛出了ConnectionRefused异常,但内置的重试逻辑似乎正在连续重试而不停止!

我没有异常处理和进行进一步的异常处理 . 我已经在上面的Spring Cloud Stream文档中阅读了Producer选项和Kafka的Binder选项,但是我看不到任何可能的自定义选项,以便让我捕获此异常 .

我是Spring Boot / Spring Cloud Stream / Spring Integration的新手(它似乎是 Cloud 流项目的底层实现) .

你还知道其他任何事情可以将这个异常级联到我的Spring Cloud Stream应用程序吗?
