Log4net recommends using only four levels, with the highest to lowest priority being ERROR, WARN, INFO, and DEBUG
#这里定义能显示到的最低级别, if you define it to the INFO level, you will not see the DEBUG level information~!
log4j.rootLogger=DEBUG
#将DAO层log记录到DAOLog, in allLog
log4j.logger.DAO=DEBUG,A2,A4
#将逻辑层log记录到BusinessLog, in allLog
log4j.logger.Businesslog=DEBUG,A3,A4
#A1 - Print to the screen

ConversionPatternparameter
Format Name Meaning
%c The full name of the class to which the output log information belongs
%d outputs the date or time of the log time point, the default format is ISO8601, or you can specify the format after it, for example: %d{yyy-MM-dd HH:mm:ss }, and the output is similar: 2002-10-18- 22:10:28
%f The class name of the class to which the output log information belongs
%l The location where the output log event occurs, that is, the statement that outputs the log information is on the line of the class it is in
%m outputs the information specified in the code, such as the message in log(message).
%n outputs a carriage return newline, "rn" for Windows and "n" for Unix
%p output priority, i.e. DEBUG, INFO, WARN, ERROR, FATAL. If the output is called debug(), then DEBUG, and so on
%r outputs the number of milliseconds it took from the start of the application to the output of the log information
%t outputs the name of the thread that generated the log event
#1 defines two outputs
log4j.rootLogger = INFO, A1, A2,A3
#2 Define the A1 output to the controller
log4j.appender.A1 = org.apache.log4j.ConsoleAppender
#3 Define the layout mode of A1 as PatternLayout
log4j.appender.A1.layout = org.apache.log4j.PatternLayout
#4 Define the output format of A1
log4j.appender.A1.layout.ConversionPattern = %-4r [%t] %-5p %c - %m%n
#5 Define A2 output to file
log4j.appender.A2 = org.apache.log4j.RollingFileAppender
#6 Define which file A2 wants to output to
log4j.appender.A2.File = F:nepalonclassesexample3.log
#7 Define the maximum length of the output file for A2
log4j.appender.A2.MaxFileSize = 1KB
#8 Define the number of backup files for A2
log4j.appender.A2.MaxBackupIndex = 3
#9 Define the layout pattern of A2 as PatternLayout
log4j.appender.A2.layout = org.apache.log4j.PatternLayout
#10 Define the output format of A2
log4j.appender.A2.layout.ConversionPattern = %d{yyyy-MM-dd hh:mm:ss}:%p %t %c - %m%n |
