What is the purpose of the LogFactory and Log interface in MyBatis?

In MyBatis, LogFactory is a factory class used to create Log instances, while the Log interface is used to log information. LogFactory is responsible for creating Log instances based on the specified logging framework type (such as log4j, slf4j, etc.) in the configuration file, and then logging information through Log instances to help developers locate issues while debugging programs. By using LogFactory and the Log interface, MyBatis achieves unified management and extension of logging, allowing developers to flexibly choose and switch between different logging frameworks, facilitating customization and extension of logging records.
