本人在运行mybatis相关代码时，因为这个问题弄了很久才发现，在网上相关的资料比较少，在此分享给大家！欢迎吐槽！！！

错误日志配置：

1. # Global logging configuration
2. log4j.rootLogger=DEBUG, stdout
3. # Console output...
4. log4j.appender.stdout=org.apache.log4j.ConsoleAppender
5. log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
6. log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

正确日志配置：

1. # Global logging configuration
2. log4j.rootLogger=ERROR, stdout
3. # MyBatis logging configuration...
4. log4j.logger.com.itheima=DEBUG
5. # Console output...
6. log4j.appender.stdout=org.apache.log4j.ConsoleAppender
7. log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
8. log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

原因：少配置的部分是（正确配置部分）第三/第四行代码，以及第二行DEBUG（错误）和ERROR（正确）不同
