我最近开始使用 Kafka，我尝试创建一个 Kafka 连接以连接到 oracle，但我做不到。我找到的信息是关于融合的，但这在 Windows 中不起作用......我如何配置一个或用 java 创建它？

我用于我的测试独立连接： cmd .\windows\connect-standalone.bat .\config\connect-standalone.properties .\config\connect-bbdd.properties ->

name=jdbc-conector 
connector.class=io.confluent.connect.jdbc.JdbcSourceConnector 
tasks.max=1 
connection.url=dbc:oracle:thin@localhost:xe 
connection.user: user 
connection.password: pwd 
mode = bulk 
topic.prefix=test
table.whitelist: mytable

错误：

你得到的这个错误：

No suitable driver found for jdbc:oracle:thin@localhost:xe 
for configuration Couldn't open connection to jdbc:oracle:thin@localhost:xe

是因为您没有使 Oracle JDBC 驱动程序可用。请参阅https://www.confluent.io/blog/kafka-connect-deep-dive-jdbc-source-connector#jdbc-drivers。

该confluent命令不能在 Windows 中本地运行，不。

但是connect-distributed，或者connect-standalone不仅在 Confluent 中，而且如果您确实在 Windows 上下载了 Confluent 平台中提供的 JDBC 连接器，它应该既可以工作又可以加载它。

否则，如果您只有 Apache Kafka，则需要单独下载 JDBC 连接器并通过plugin.pathConnect 配置文件中提到的属性自行设置。
