log4j 每个日志条目带有时间戳
这是我的日志输出
INFO main digestemails - process inbox
INFO main digestemails - checking for emails in c:\development\DCMail\email\KN-Source
INFO main digestemails - digesting [email protected]
INFO main digestemails - extracting attachments
INFO main digestemails - no attachments or no attachments supported
INFO main digestemails - updating database
INFO main digestemails - email -> COMPLETED folder
INFO main digestemails -
我想要每个日志消息的时间戳，即
INFO 2008-12-25 13:14:00 digestemails - email -> COMPLETED folder
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=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
我该怎么做？
this is my log output
INFO main digestemails - process inbox
INFO main digestemails - checking for emails in c:\development\DCMail\email\KN-Source
INFO main digestemails - digesting [email protected]
INFO main digestemails - extracting attachments
INFO main digestemails - no attachments or no attachments supported
INFO main digestemails - updating database
INFO main digestemails - email -> COMPLETED folder
INFO main digestemails -
I would like a time stamp per log message ie
INFO 2008-12-25 13:14:00 digestemails - email -> COMPLETED folder
here is my log4j config file
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=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n

在 PatternLayout 中使用
%d。%d还可以采用%d{dd MMM yyyy HH:mm:ss,SSS}中的格式模式，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。Use
%din your PatternLayout.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.我的属性文件的摘录

您可以在 log4j javadoc 中找到更多转换字符的用法。例如，在 http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/PatternLayout.html。
