Question

我正在寻找连接 mysql --> debezium --> kafka（融合云）。我想知道是否有人可以帮助我解决此错误消息：

<块引用>

未能找到任何实现连接器且名称与 io.debezium.connector.mysql.MySqlConnector 匹配的类。

我的 kafka worker 文件中有 debezium 的 jar 文件：

<块引用>

plugin.path=/home/ec2-user/kafka/plugins

插件文件夹内容如下：

-antlr4-runtime-4.7.2.jar

-debezium-api-1.5.3.Final.jar

-debezium-connector-mysql-1.5.3.Final.jar

-debezium-core-1.5.3.Final.jar

-debezium-ddl-parser-1.5.3.Final.jar

-failureaccess-1.0.1.jar

-guava-30.0-jre.jar

-mysql-binlog-connector-java-0.25.1.jar

-mysql-connector-java-8.0.21.jar

当我启动分发器时，我看到添加了插件：

但是，当我运行 curl 命令时：

<块引用>

curl -s -X POST -H 'Content-Type: application/json' --data @debe-connector.json http://localhost:8083/connectors -v

我收到错误：

<块引用>

未能找到任何实现连接器且名称与 io.debezium.connector.mysql.MySqlConnector 匹配的类。

知道我可能遗漏了什么吗？

谢谢，

您需要将debezium mysql connector的所有jar文件放在一个目录中

/home/ec2-user/kafka/plugins/debezium-connector-mysql

而不是刚好

/home/ec2-user/kafka/plugins

什么会导致这个 debezium kafka 连接器错误？
