MyBatis日志实现

maven项目resources文件夹下log4j.properties　　

　　其作用是输出controller包下参与Mybatis的类的SQL语句输出。如果包名不一样，请根据自己的项目情况调整。

# Global logging configuration
log4j.rootLogger=ERROR, stdout
# MyBatis logging configuration...
log4j.logger.controller=TRACE
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

mybatis-config.xml文件添加

　　<setting name="logImpl" value="STDOUT_LOGGING"/>
