Mybatis入门：log4j配置、全局配置、mapper配置、测试类四部分

>log4j配置

#info,error. 
log4j.rootLogger=debug,stdout
# log4j.logger.org.apache.ibatis=debug
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

>全局配置

 

>mapper配置
