Question

我让Kafka运行在远程服务器上，并且我正在使用spring框架（java）生成和使用消息。为了在我的本地计算机上进行测试，我仅产生1个事件。这是我如何产生消息的简化代码：

import org.springframework.kafka.core.KafkaTemplate;

...

@Autowired
KafkaTemplate<String, String> kafkaTemplate;

...

kafkaTemplate.send("sampletopic", "1234").get();

...

此处有效负载只是一个用户ID字符串。执行send函数时，出现以下错误：

kafka ..错误：java.util.concurrent.ExecutionException： org.springframework.kafka.core.KafkaProducerException：发送失败；嵌套的异常是org.apache.kafka.common.errors.TimeoutException： 1个样本的主题0记录已过期：自30028毫秒过去了批量创建加上持续时间

以下是我收到错误之前得到的相关日志：
