Change logger to slf4j to make it able to run in native mode on spring-boot 4

Why are you only modifying the ClassPathMapperScanner.java?

@ridwannurhayat Spring is using commons-logging, while I personally prefer slf4j, would it make more sense to align it with its actual underlying usage? Maybe it doesn't quite matter. For some time I've been suggesting we dump mybatis logging entirely and move to slf4j, most modules already are using slf4j. But I did want to note that spring itself is not.

This will have to come at a later time. The logging is internal and should be removed or at least deprecated. All the others would need cleaned up. Consideration should be taken into account if we align to spring here rather than spring boot. Also note that mybatis internals is still going to use the logging abstracted away so this may not be worthwhile until we make a firm stance on mybatis after 3.6.0 release cycle.
