在启动日志中，它清楚地显示了正在加载 JDBC 连接器:

In the startup logs, it clearly shows loading JDBC Connectors:

[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)

但它失败并出现以下异常:

But it fails with following exception:

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
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=xxxx
You can also find the above list of errors at the endpoint `/{connectorType}/config/validate`
    at org.apache.kafka.connect.util.ConvertingFutureCallback.result(ConvertingFutureCallback.java:79)
    at org.apache.kafka.connect.util.ConvertingFutureCallback.get(ConvertingFutureCallback.java:66)
    at org.apache.kafka.connect.cli.ConnectStandalone.main(ConnectStandalone.java:110)

也尝试更改插件目录，但没有奏效.也尝试将融合的 share/* 移动到/usr/share/java 但它也没有奏效.

Tried changing the plugin directories too but it didn't work. Tried moving the confluent share/* to /usr/share/java too but it also didn't work.

推荐答案

1. 从 URL 下载 JAR:https://dev.mysql.com/downloads/connector/j/5.1.html

放入插件目录

需要开始从 MySql 中提取数据.

It will take start pulling data from MySql.
