kafka报java.io.EOFException错误解决方案

在项目中使用kafka来获取第三方推送的生产端数据进行消费，在项目运行过程中发现consumer.poll(1000)方法一直报java.io.EOFException错误，如下所示：

看网上说是kafka版本问题，我这边看了下项目kafka使用的是kafka-clients-0.10.0.0.jar，
依赖是

	    <dependency>
			<groupId>org.apache.kafka</groupId>
			<artifactId>kafka-clients</artifactId>
			<version>0.10.0.0</version>
		</dependency>

使用这个kafka-clients依赖会有一个问题，那就是代码中ConsumerRecords<String, String> records = kafkaConsumer.poll(1000);会进入死循环且报java.io.EOFException错误，于是试了好几个kafka-clients版本都不行，最后注释掉kafka-clients依赖换个kafka依赖：

		<!--<dependency>-->
			<!--<groupId>org.apache.kafka</groupId>-->
			<!--<artifactId>kafka-clients</artifactId>-->
			<!--<version>0.10.0.0</version>-->
		<!--</dependency>-->
		<dependency>
			<groupId>org.apache.kafka</groupId>
			<artifactId>kafka_2.12</artifactId>
			<version>2.1.0</version>
		</dependency>

代码中对应修改一下这个poll()方法，改为ConsumerRecords<String, String> records = kafkaConsumer.poll(Duration.ofMillis(1000));再次启动项目就不会无限的循环报错了。

至于kafka怎么使用论坛有好多帖子，就不一一赘述了。这次只是记录本项目中的报错以及修复过程，积累一些经验供以后参考。
