In addition to the root logger, you can configure individual loggers with their own appenders. Assuming you are calling your loggers ClassA and ClassB you can do:

<root>
     <appender-ref ref="CommonAppender" />
</root>
<logger name="ClassA">
     <appender-ref ref="AppenderA" />
</logger>
<logger name="ClassB">
     <appender-ref ref="AppenderB" />
</logger>

This is further described here.
