使用mysql-connector-java 6.0.3的时候，数据源建立失败

[89333367]

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>6.0.3</version>
</dependency>

使用这个驱动的时候，数据源建立失败

如果使用

<dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.39</version>
        </dependency>

这个驱动就可以

从6.0开始mysql driver的class变成com.mysql.cj.jdbc.Driver了，楼主确定驱动没有写错？

升级驱动6.0.3，druid1.0.23后出现一个NPE

Loading class com.mysql.jdbc.Driver'. This is deprecated. The new driver class iscom.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

原因应该是没有“com.mysql.jdbc.MySQLConnection”类了。
不过项目启动任然是成功的。
