log4j different modules output to different files

1. Achieve the goal

Log information for different businesses needs to be printed to a different file, generating a file every day or every hour. For example, the registered information is printed to Register.log, and a register-day is generated every morning. log files, logs of login information are printed into a login.log file, login-month day. Log.

2. Maven Configuration

3. Configuration files

By default, log4j resolves the src/main/resources/log4j.properties file, and the following is the contents of the Log4.properties file.

# # # #父级Loggerlog4j. rootcategory=info,stdout### Child Logger If the appender inside the parent logger (log4j.rootcategory set above) is output, the default is True # # # is true: sub-level logger output will also be in the parent logger inside Output # # # is false: Log log will only be in the current level of logger output, does not output log4j.addivity.org.apache=truelogdir=/users/zhengcanrui/work/test/logs in the parent logger log4j.appender.stdout= org.apache.log4j.consoleappenderlog4j.appender.stdout.layout= ORG.APACHE.LOG4J.PATTERNLAYOUTLOG4J.APPENDER.STDOUT.LAYOUT.CONVERSIONPATTERN=%P\:%D{YYYYMMDD HH\:mm\:ss}%c\:%m% n######## #自定义日志输出 ########## log4j.appender.file= Org.apache.log4j.dailyrollingfileappenderlog4j.appender.file.file=${logdir}/file.loglog4j.appender.file.layout =org.apache.log4j.patternlayoutlog4j.appender.file.layout.conversionpattern=%d-[ts]%p%t%c-%m%n# #register模块输出 # # # # is used to control the log information, such as: The following information is at least info will be output to the register file Log4j.logger.register=info,register log4j.appender.register= Org.apache.log4j.DailyRollingFileAppender log4j.appender.register.file=${logdir}/ Register.loglog4j.appender.register.datepattern= ' _ ' yyyy-mm-dd '. log' Log4j.appender.register.layout=org.apache.log4j.patternlayout Log4j.appender.register.layout.ConversionPattern =%d%p [%c%l%l]-%m%nlog4j.additivity.register=true # #login模块输出 Log4j.logger.login=info,login log4j.appender.login= Org.apache.log4j.DailyRollingFileAppender Log4j.appender.login.file=${logdir}/login.log

A few attributes to note:

log4j.additivity-Module Name: Sets whether the sub-logger is output in the parent logger.

Name of module: Log4j.appender. Module name. Properties.

4. Test class

ImportOrg.apache.log4j.Logger;Importorg.slf4j.LoggerFactory;/*** Created by Zhengcanrui on 16/7/27.*/ Public classLoggerutil {Private Static FinalLogger file = Logger.getlogger ("File"); Private Static FinalLogger Register = logger.getlogger ("register"); Private Static FinalLogger login = Logger.getlogger ("Login"); Private Static FinalLogger Goldcoin = Logger.getlogger ("Goldcoin"); Private Static FinalLogger recharge = Logger.getlogger ("Recharge"); Private Static FinalLogger JJJ = Logger.getlogger (loggerutil.class. GetName ()); Private Static FinalLogger FILE = Logger.getlogger ("Appender1"); Private StaticOrg.apache.log4j.Logger log = Logger.getlogger (loggerutil.class);  Public Static voidLoginfo (String log) {file.info (log); }     Public Static voidRegisterinfo () {Register.info ("[Register] DDD" ); }     Public Static voidLogininfo () {Login.info ("[Login] 222" ); }     Public Static voidMain (string[] args) {/*Loginfo ("11");        Registerinfo (); Logininfo ();*/        /*login.info ("[login] greatly greatly greatly");        Register.debug ("2222"); Register.info ("[Register] everyone for all");*/        //jjj.info ("test"); //Log.info (222);File.info ("334343"); Register.info ("2222"); }}

Results:

1) Console

info:20160801 12:27:57 appender1:334343INFO:20160801 12:27:57 register:2222

2) Generate file

3) Contents of the file
