As the error indicates, your application does not have permissions to use transactions.如错误所示，您的应用程序无权使用事务。 Using transactions requires special permissions that you can enable via ACLs.使用事务需要您可以通过 ACL 启用的特殊权限。
See the docs for more details on what permission you need to grant: https://docs.confluent.io/current/kafka/authorization.html#enabling-authorization-for-idempotent-and-transactional-apis有关您需要授予的权限的更多详细信息，请参阅文档： https : //docs.confluent.io/current/kafka/authorization.html#enabling-authorization-for-idempotent-and-transactional-apis
