MySQL Connector/J 8.0 Developer Guide  /  ...  /  Changes in the Connector/J API

4.3.1.3 Changes in the Connector/J API

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.Driver in MySQL Connector/J has changed from com.mysql.jdbc.Driver tocom.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.ExceptionInterceptor to com.mysql.cj.exceptions.ExceptionInterceptor

  • StatementInterceptor: from com.mysql.jdbc.StatementInterceptorV2 to com.mysql.cj.interceptors.QueryInterceptor

  • ConnectionLifecycleInterceptor: from com.mysql.jdbc.ConnectionLifecycleInterceptor tocom.mysql.cj.jdbc.interceptors.ConnectionLifecycleInterceptor

  • AuthenticationPlugin: from com.mysql.jdbc.AuthenticationPlugin to com.mysql.cj.protocol.AuthenticationPlugin

  • BalanceStrategy: from com.mysql.jdbc.BalanceStrategy to com.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.
