Java project packaged into executable jar with log4j writes the log in the directory where the JAR resides

Develop a demo when you want to output the log to the final packaged jar in the directory, from the online learning experiment after finishing the configuration as follows,

Log4j.properties

Log4j.rootlogger =Info,console,logfilelog4j.appender.console=Org.apache.log4j.ConsoleAppenderlog4j.appender.console.Threshold=INFOlog4j.appender.console.ImmediateFlush=trueLog4j.appender.console.Target=System.outlog4j.appender.console.layout=Org.apache.log4j.PatternLayoutlog4j.appender.console.layout.ConversionPattern=%d{yyyy-mm-dd HH:MM:SS} [%p]%m%Nlog4j.appender.logFile=Org.apache.log4j.FileAppenderlog4j.appender.logFile.ImmediateFlush=trueLog4j.appender.logFile.Append=falselog4j.appender.logFile.Encoding=utf-8Log4j.appender.logFile.File=JarDemo.loglog4j.appender.logFile.layout=Org.apache.log4j.PatternLayoutlog4j.appender.logFile.layout.ConversionPattern=%d{yyyy-mm-dd HH:MM:SS} [%p]%m%n

Main.java

Private Static Logger Logger = Loggerfactory.getlogger (Main.  Class);     Static {        new File (""). GetAbsolutePath ();         = (Fileappender) Org.apache.log4j.Logger.getRootLogger (). Getappender ("LogFile");         + File.separator + "JarDemo.log");    }

When finally packaged as a jar execution, a jarDemo.log log file is produced in the same directory as the jar file, and if run with idea, the log file will be at the root of the project where the source code is located.
