Disable the log from specific class/jar via logback.xml

In your logback.xml configuration adding the following element should work

<logger name="org.hibernate.engine.jdbc.spi.SqlExceptionHelper" level="OFF"/>

Add the following to your logback.xml configuration file:

<logger name="org.hibernate.engine.jdbc.spi.SqlExceptionHelper" level="OFF"/>

The instruction: level="OFF" tells Logback to disable all log output for a given logger.
