Question

我正在尝试在Spring Boot中开发一个Kafka Consumer。我可以在Kafka Tool中设置Kafka群集，并可以手动从中读取消息。我也在Spring Boot中使用相同的配置，但最终出现以下错误和此警告。

Answer 1

Kerberos与SSL不同。 SSL用于加密，Kerberos用于身份验证。

请参见Configuring Kafka Clients (for SSL)。

请参见Authentication using SASL/Kerberos和Configuring Kafka Clients

无效的密钥库格式，BootStrap代理已断开连接
