### 输出到日志文件 ###
##  其中File 可以采用绝对路径 亦可以采用相对路径 catalina.home 是tomcat目录  如果没有logs文件夹 将会报错  ##
##  更加倾向于将日志文件放在  tomcat的日志目录下${catalina.home}/logs/salesmanb2bError.log ##
##  绝对路径如：e:/salesmanb2bError.log ##
log4j.logger.daily=INFO,D
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ${catalina.home}/logs/helloworld/helloworld.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = INFO
log4j.appender.D.layout = org.apache.log4j.PatternLayout
