Java Kafka订阅服务器客户端0.10.2-Spring集成-无效\u主题\u异常

我正在尝试使用Spring集成订阅Kafka服务器。我可以在应用程序日志中看到kafka connect日志。考虑到以下相同的情况

如果我缺少任何必要的配置，请告诉我

即使主题存在，我仍在日志中收到以下警告

WARN org.apache.kafka.clients.NetworkClient Error while fetching metadata with correlation id 3 : {"notification.email.click"=INVALID_TOPIC_EXCEPTION}

---

由于该主题未关联到我的消费者组

正如文档所述，当 “客户端试图对无效主题执行操作。”

这通常发生在客户端由于许多原因无法发布时

• 未创建主题
• 客户端和kafka服务器之间的防火墙配置
• 等

---

因为在您的情况下，您的配置是未知的。您可以从调试上述原因开始。

）不是主题名称的法定字符

根据卡夫卡文件，主题命名的法定字符包括：

ASCII字母数字

定义了以下法律特征：

val legalChars = "[a-zA-Z0-9\\._\\-]"
private val maxNameLength = 249
private val rgx = new Regex(legalChars + "+")
