c.z.hikari.util.DriverDataSource - Registered driver with driverClassName=oracle.jdbc.driver.OracleDriver was not found, trying direct instantiation.

Hi there,

getting this warning message while starting micro service, which is running with spring boot & latest Hikari.

Is this something I should be worring about?

The driver class is in classpath, btw.

Cheers,

David

It’s not something to be worried about, but is a little odd. As per specification the driver jar should have a META-INF/services/java.sql.Driver file whose contents contains the name if the driver class. This is typically how the DriverManager registers drivers; by scanning all the jars in the class path and automatically registering them. For whatever reason, you driver is not getting registered. Could be a classloader thing. Either way, if direct instantiation works, the pool is good to go.
