log4j配置文�g的位�|?class文�g的根目录�?或者源文�g�Ҏ��目录�?

monster — Fri, 15 Jun 2007 06:32:00 GMT

log4j配置文�g的位�|�应该放在class文�g的根目录�?或者源文�g�Ҏ��目录�?,不要攑֜�子目录下,否则会由于找不到log4j配置文�g而出�?
一个quartz用的log4j配置文�g内容如下:

#DEBUG用来定义输出�U�别�Q�比DEBUG高的都可以输出，后面的stdout�Q�File��出日志的输出地方
log4j.rootLogger=DEBUG, stdout,FILE
#定义stdout输出的格�?br>log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%c{1} - %m%n
#定义文�g输出的格�?br>log4j.appender.FILE=org.apache.log4j.FileAppender
log4j.appender.FILE.File=d:\\log.txt
log4j.appender.FILE.Append=true
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.ConversionPattern=[send mail info] %d - %c -%-4r [%t] %-5p %c %x - %m%n

#其中�Q�Log4j提供的appender有以下几�U�：
#org.apache.log4j.ConsoleAppender�Q�控制台�Q�，
#org.apache.log4j.FileAppender�Q�文�Ӟ��Q?nbsp;
#org.apache.log4j.DailyRollingFileAppender�Q�每天��生一个日志文�Ӟ��Q?nbsp;
#org.apache.log4j.RollingFileAppender�Q�文件大��到达指定尺寸的时候��生一个新的文�Ӟ��Q?nbsp;
#org.apache.log4j.WriterAppender�Q�将日志信息以流格式发送到��L��指定的地方）

#其中�Q�Log4j提供的layout有以下几�U�：
#org.apache.log4j.HTMLLayout�Q�以HTML表格形式布局�Q�，
#org.apache.log4j.PatternLayout�Q�可以灵�z�d��指定布局模式�Q�，
#org.apache.log4j.SimpleLayout�Q�包含日志信息的�U�别和信息字�W�串�Q�，
#org.apache.log4j.TTCCLayout�Q�包含日志��生的旉��、线�E�、类别等�{�信息）

# 下面是步骤，�?0�?

#1 定义了两个输出端
#log4j.rootLogger = debug, A1, A2
#2 定义A1输出到控制器
#log4j.appender.A1 = org.apache.log4j.ConsoleAppender
#3 定义A1的布局模式为PatternLayout
#log4j.appender.A1.layout = org.apache.log4j.PatternLayout
#4 定义A1的输出格�?br>#log4j.appender.A1.layout.ConversionPattern = %-4r [%t] %-5p %c - %m%n
#5 定义A2输出到文�?br>#log4j.appender.A2 = org.apache.log4j.RollingFileAppender
#6 定义A2要输出到哪一个文�?br>#log4j.appender.A2.File = D:\\hello.log
#7 定义A2的输出文件的最大长�?br>#log4j.appender.A2.MaxFileSize = 1KB
#8 定义A2的备份文件数
#log4j.appender.A2.MaxBackupIndex = 3
#9 定义A2的布局模式为PatternLayout
#log4j.appender.A2.layout = org.apache.log4j.PatternLayout
#10 定义A2的输出格�?br>#log4j.appender.A2.layout.ConversionPattern = %d{yyyy-MM-dd hh:mm:ss}:%p %t %c


#log4j.appender.R=org.apache.log4j.RollingFileAppender   //指定以文件的方式输出日志
#log4j.appender.R.File=c:/sys.html   //文�g位置
#log4j.appender.R.MaxFileSize=500KB   //文�g最大尺�?nbsp;
#log4j.appender.R.MaxBackupIndex=1   //备䆾�?nbsp;
#log4j.appender.R.layout=org.apache.log4j.HTMLLayout   //文�g的格式�ؓHtml格式
#log4j.appender.R.layout=org.apache.log4j.PatternLayout
#log4j.appender.R.layout.ConversionPattern=%d{yyyy-MM-dd   HH:mm:ss,SSS}   [%t]   [%c]   [%p]   -   %m%n

#输出格式
#%m 输出代码中指定的消息
#%p 输出优先�U�，即DEBUG�Q�INFO�Q�WARN�Q�ERROR�Q�FATAL
#%r 输出自应用启动到输出该log信息耗费的毫�U�数
#%c 输出所属的�cȝ��Q�通常��是所在类的全�?br>#%t 输出产生该日志事件的�U�程�?br>#%n 输出一个回车换行符�Q�Windows�q�_��?#8220;\r\n”�Q�Unix�q�_��?#8220;\n”
#%d 输出日志旉��点的日期或时��_��默认格式为ISO8601�Q�也可以在其后指定格式，比如�Q?d{yyy MMM dd HH:mm:ss,SSS}�Q�输出类��|��2002�q?0�?8�?22�Q?0�Q?8�Q?21
#%l 输出日志事�g的发生位�|�，包括�cȝ��名、发生的�U�程�Q�以及在代码中的行数。�D例：Testlog4.main(TestLog4.java:10)
