MySQL currently provides the java driver Connection/J, can be downloaded from the MySQL official website, and find the mysql-connector-java-3.0.15-ga-bin.jar file, this driver is pure java driver, do not need to do other configuration.
Step 2: dynamically specify classpath
If you need to dynamically specify the classpath for execution, use the-cp method during execution. Otherwise, add the above. jar file to the classpath environment variable.
Step 3: load the driver
Try {
Class. forName ("com. mysql. jdbc. Driver ");
System. out. println ("Success loading Mysql Driver! ");
}
Catch (Exception e)
{
System. out. println ("Error loading Mysql Driver! ");
E. printStackTrace ();
}
