here is my log4j config file
这是我的 log4j 配置文件
log4j.rootLogger=debug, stdout, R
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=c:\development\DCMail\logs\digestlogfolder\digest-logfile.log
log4j.appender.R.MaxFileSize=100KB
# Keep one backup file
log4j.appender.R.MaxBackupIndex=1

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

Use %din your PatternLayout.
%d在您的 PatternLayout 中使用。
Also %dcan take a format pattern as in %d{dd MMM yyyy HH:mm:ss,SSS}you can pick and choose the elements that you want. When the format pattern is omitted the date will be in ISO8601 format.
也%d可以采用格式模式，因为%d{dd MMM yyyy HH:mm:ss,SSS}您可以选择所需的元素。当省略格式模式时，日期将采用 ISO8601 格式。

You can find more conversion characters usage in log4j javadoc.For example, at http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/PatternLayout.html.
