### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.err
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### direct messages to file mylog.log ###

log4j.appender.file.File=d:\\mylog.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### set log levels - for more verbose logging change 'info' to 'debug' ###
### fatal error warn info debug trace
log4j.rootLogger=info, stdout

 或者：（推荐）参考：https://www.cnblogs.com/xiaobaizhiqian/p/7956690.html

### 配置根 ###
log4j.rootLogger = debug,console ,fileAppender,dailyRollingFile,ROLLING_FILE,MAIL,DATABASE

### 设置输出sql的级别，其中logger后面的内容全部为jar包中所包含的包名 ###
log4j.logger.org.apache=dubug
