我让kafka在远程服务器上运行，我使用springframework（java）生成和使用消息。为了在本地机器上进行测试，我只生成一个事件。下面是我如何生成消息的简化代码：

import org.springframework.kafka.core.KafkaTemplate;

...

@Autowired
KafkaTemplate<String, String> kafkaTemplate;

...

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

...

这里的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。。error:java.util.concurrent.executionexception：org.springframework.kafka.core.kafkaproducerexception:发送失败；嵌套异常为org.apache.kafka.common.errors.timeoutexception:自批创建加上延迟时间后，sampletopic-0的1条记录已过期30028毫秒
以下是获取错误之前获取的相关日志：
