CMD:

connectstandalone/grid/1/mukul/confluent-5.0.0/etc/kafka/connect-standalone.properties/grid/1/mukul/confluent-5.0.0/etc/kafka-connect-jdbc/source-quickstart-sqlite.properties

在启动日志中，它清楚地显示了加载JDBC连接器：

[2018-08-09 06:59:30,072] INFO Loading plugin from: /grid/1/mukul/confluent-5.0.0/share/java/kafka-connect-jdbc (org.apache.kafka.connect.runtime.isolation.DelegatingClassLoader:218)

但它失败了，但有以下例外：

Invalid value java.sql.SQLException: No suitable driver found for jdbc:mysql://10.32.177.178:3306/test&user=xxxx&password=xxxx for configuration Couldn't open connection to jdbc:mysql://10.32.177.178:3306/test&user=xxxx&password=xxx

也尝试过更改插件目录，但没有成功。尝试将合流共享/*移动到/usr/share/java，但也没有成功

从URL下载JAR：

放置在插件目录中

运行连接

开始从MySql中提取数据还需要一段时间。

可能会晚一点。当我使用kafka jdbc连接器连接DB2时，我遇到了同样的问题“找不到驱动程序…”

第一种可能的解决方案：

我通过将DB2驱动程序放置在jdbc连接器所在的确切位置来解决这个问题。 在卡夫卡连接中：

find/-name kafka connect jdbc\*.jar

从上述命令找到位置后，在该位置复制DB2 jar：

cp{yourdb2jarlocation}/DB2.jar{copy the location from'find'command}

范例

cp/Download/db2.jar/Users/share/java/kafka connect java/

重新启动kafka connect，它将获取DB2驱动程序

第二种可能的解决方案：

下载JT400JAR（jdk-8）并将其放在其他jdbc驱动程序（DB2、SQL等）旁边

快乐编码：）

你指的是哪个插件目录？如何确定正在使用哪个目录？@ValerianPereira:您需要将Jar复制到etc/kafka/connect-distributed.properties文件中提到的plugin.path=share/java目录，或者您可以使用etc/kafka/connect-standalone.properties文件中的plugin.path配置来实现独立模式。感谢您的帮助@mukul我已经修复了这个问题。JAR被很好地放置在share/javadir中，但是，为了使更改生效，我没有重新启动服务。
