我正在发展 Spring Boot + Apache Kafka + Apache Zookeeper 例子。我已安装/设置 Apache Zookeeper and Apache Kafka 在我的本地windows计算机上。我从link得到了一个参考：https://www.tutorialspoint.com/spring_boot/spring_boot_apache_kafka.htm 并按原样执行代码：
设置：https://medium.com/@shaaslam/installing-apache-kafka-on-windows-495f6f2fd3c8
错误：

花了几个小时后，我发现我应该用下面的 KafkaConsumerConfig 我也是。
通过以下更改，代码可以正常工作。

props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, "localhost:9092");

此问题可能是由于spring boot版本和kafka版本不匹配造成的。我可以用下面的矩阵来解析。
Spring 启动版本：

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.4.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

kafka版本maven依赖于spring启动版本

<dependency>
        <groupId>org.springframework.kafka</groupId>
        <artifactId>spring-kafka</artifactId>
    </dependency>

Kafka版本：Kafka2.12-2.2.0
zookeeper版本：apache-zookeeper-3.5.5
application.yml文件详细信息如下：

server:
  port: 9000
spring:
  kafka:
    consumer:
      bootstrap-servers:
      - localhost:9092
      group-id: group_id
      auto-offset-reset: earliest
      key-deserializer: org.apache.kafka.common.serialization.StringDeserializer
      value-deserializer: org.apache.kafka.common.serialization.StringDeserializer
    producer:
      bootstrap-servers:
      - localhost:9092
      key-deserializer: org.apache.kafka.common.serialization.StringDeserializer
      value-deserializer: org.apache.kafka.common.serialization.StringDeserializer
