篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了连接Kafka 3.0中的主要问题-org.apache.kafka.common.KafkaException：无法加载SSL密钥库相关的知识，希望对你有一定的参考价值。
我正在尝试使用SSL连接到Kafka 3.0，但在加载SSL密钥库时遇到问题
我尝试了很多可能的值，但没有帮助
我尝试过更改位置，更改位置的值，但是仍然没有帮助

任何人都可以提供帮助，密钥库可能是什么问题？提示“无法加载类型为JKS的SSL密钥库/kafka.keystore.jks”
答案
原因：java.io.FileNotFoundException： kafka.keystore.jks（系统找不到指定的文件）
