用struts+hibernate实现案例

log4j.rootLogger=error, stdout, R
  log4j.appender.stdout=org.apache.log4j.FileAppender
  log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
  
  log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss}  %p %c{1}.%M(%L) | %m%n
  log4j.appender.stdout.MaxFileSize=30MB
  log4j.appender.stdout.MaxBackupIndex=1  
  log4j.appender.stdout.file=d:\\output.log

  # Pattern to output the caller's file name and line number.
 

  log4j.appender.R=org.apache.log4j.RollingFileAppender
  log4j.appender.R.File=example.log
  log4j.appender.R.MaxFileSize= 100KB

  # Keep one backup file
  log4j.appender.R.MaxBackupIndex=1

  log4j.appender.R.layout=org.apache.log4j.PatternLayout
  log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
