MyBatis version

Database vendor and version

Any

Test case or example project

None

Steps to reproduce

1. Change to JKD14 as follow:

sqlSessionFactory.getConfiguration().setAutoMappingUnknownColumnBehavior(AutoMappingUnknownColumnBehavior.WARNING);
sqlSessionFactory.getConfiguration().setLogImpl(Jdk14LoggingImpl.class); // Change to JDK14

2. Run an application

Expected result

Output a log using the logger of JDK14(via specified log implementation).

Actual result

But output a log using the logger of SLF4J(In my application, SLF4J's provider is log4j). this changes cannot apply to some class.

In this current implementation, the logger initialization has been performed before applying a logger configuration.

For example:

mybatis-3/src/main/java/org/apache/ibatis/session/AutoMappingUnknownColumnBehavior.java

Line 65 in d5f024c

private static final Log log = LogFactory.getLog(AutoMappingUnknownColumnBehavior.class);

mybatis-3/src/main/java/org/apache/ibatis/executor/loader/javassist/JavassistProxyFactory.java

Line 47 in d5f024c

private static final Log log = LogFactory.getLog(JavassistProxyFactory.class);

Loggers of these classes has been initialized before applying logger configuration because the Configuration class refers these classes.
