"Loading class com.mysql.jdbc.Driver ... is deprecated" message

I got an error

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.

Could someone explain why?

Solution

  • It isn't an error; it is a warning (or advisory) message resulting from a

    Class.forName("com.mysql.jdbc.Driver")

    call. Your code continues to run despite the message.

    It is mainly telling you that the name of the driver class has changed to com.mysql.cj.jdbc.Driver. So, instead use:

    Class.forName("com.mysql.cj.jdbc.Driver")

    It is also letting you know that since Java 6 (JDBC 4.0) it is usually not necessary to manually load the driver class using Class.forName anyway, because JDBC is now able to load the correct driver itself (provided that the driver .jar is available on the class path).
