java - Kafka 订阅者客户端 0.10.2 - Spring 集成 - INVALID_TOPIC_EXCEPTION

Question

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 连接登录。鉴于以下相同。

如果我在这里缺少任何必要的配置，请告诉我。

即使主题存在，我也会在记录器中收到警告。

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

由于哪个主题未分配给我的消费者组。

Answer 1

您的主题名称是“notification.email.click”(包括引号)。双引号 (") 不是主题名称的合法字符。

根据Kafka文档，主题命名的合法字符包括:

1. ASCII 字母数字
2. .
3. _
4. -

source code for 0.10.2定义以下合法字符:

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