mysqlCDC运行报错 ERROR com.zaxxer.hikari.pool.HikariPool - connection-pool-s201:3306 - Exception during pool initialization.

[frankandroid]

mysql版本：5.7.16
用的connector版本是8.0.16

mysql
mysql-connector-java
8.0.16

按照wiki代码运行报错[flink-akka.actor.default-dispatcher-6] ERROR com.zaxxer.hikari.pool.HikariPool - connection-pool-s201:3306 - Exception during pool initialization.

mysql可正常连接访问，但是运行代码报错
