Java 无法通过KAFKA api连接到EventHub

我通过kafka库连接事件中心时遇到以下异常

 Caused by: org.apache.kafka.common.protocol.types.SchemaException: Error reading field 'sasl_auth_bytes': Bytes size -1 cannot be negative

消费者属性如下所示：

bootstrap.servers=XXX-topics.servicebus.windows.net:9093
security.protocol=SASL_SSL
sasl.mechanism=PLAIN
sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required username="$ConnectionString" password="Endpoint=sb://XXXX-topics.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=**************************";

发布到基本计划事件中心时会发生此错误，因为基本计划不支持通过Kafka协议进行交互

---

升级到标准计划可以解决此问题。

您还需要使用ssl.ca.cert=

---

因为您使用的是SASL_SSL，而不是SASL_明文。我们需要使用SASL_SSL连接到azure事件中心。

您正在运行的客户端是什么？@Serkant Karaca Java code。。客户的意思是我没有得到它。我是说哪个卡夫卡客户和哪个版本？这个@Serkant Karaca是的，我现在可以连接了。问题在我的SharedAccessKey中。感谢您的更新。@PonmanikandanBoothalingam我收到了相同的问题，您是如何确定您的问题及其解决方案的？
