MySQL :: MySQL Connector/J 8.0 Developer Guide :: 4.3.1.3 Changes in the Connector/J API https://dev.mysql.com/doc/connector-j/8.0/en/connector-j-api-changes.html
This section describes the changes to the Connector/J API going from version 5.1 to 8.0. You might need to adjust your API calls accordingly:
-
The name of the class that implements
java.sql.Driverin MySQL Connector/J has changed fromcom.mysql.jdbc.Drivertocom.mysql.cj.jdbc.Driver. The old class name has been deprecated. -
The names of these commonly-used interfaces have also been changed:
-
ExceptionInterceptor: from
com.mysql.jdbc.ExceptionInterceptortocom.mysql.cj.exceptions.ExceptionInterceptor -
StatementInterceptor: from
com.mysql.jdbc.StatementInterceptorV2tocom.mysql.cj.interceptors.QueryInterceptor -
ConnectionLifecycleInterceptor: from
com.mysql.jdbc.ConnectionLifecycleInterceptortocom.mysql.cj.jdbc.interceptors.ConnectionLifecycleInterceptor -
AuthenticationPlugin: from
com.mysql.jdbc.AuthenticationPlugintocom.mysql.cj.protocol.AuthenticationPlugin -
BalanceStrategy: from
com.mysql.jdbc.BalanceStrategytocom.mysql.cj.jdbc.ha.BalanceStrategy.
-
信息: Loading XML bean definitions from class path resource [Beans.xml]
Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.
