Today, I will talk to you about what log modules there are in MyBatis, which may not be well understood by many people. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.

The package where the log function code is located

Org.apache.ibatis.logging

Loading order of the log module

Mybatis does not have its own log module. It uses third-party logs (there are also jdk's own logs). The loading order of slf4J → commonsLoging → Log4J2 → Log4J → JdkLog
