在 WebLogic 14c (14.1.1.0.0）控制台配置MySQL数据源，如果选择的数据库驱动为：
com.mysql.jdbc.Driver
在数据源的 Target 服务运行时，会在服务日志里面打印如下的提示信息：
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.

在WebLogic安装目录下搜索，可以发现下面的驱动jar包
./Oracle/Middleware/Oracle_Home/oracle_common/modules/mysql-connector-java-commercial-8.0.14/mysql-connector-java-commercial-8.0.14.jar下载到本地，使用压缩软件打开jar包，可以在com.mysql.cj.jdbc的包路径下，找到Driver.class类文件。
如果本地应用程序项目使用JDK1.8或者JDK11开发，且需要部署在WebLogic 14c服务器上，建议开发人员在本地项目中也采用上面的驱动Jar包和数据库驱动。
