在 maven 项目中将 log4j.properties 放在哪里？

Question

I know it's a cliché question and I readed all the documents and I tried many solutions but always no solution worked for me.! but I put the log4j.properties in the src/main/resources and also in src/main/java and I've added PropertyConfigurator.configure("log4j.properties"); to my class but when I turn my project to a Runnable JAR it shows me:

C:\Users\eya\Desktop>java -jar RestCallAutomation.jar
log4j:WARN No appenders could be found for logger (com.infosquare.restautomation.AppController).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

log4j:ERROR Ignoring configuration file [log4j.properties].

here is the architecture of my project: maven project Architecture

and here is the log4j.properties:

# Root logger option
log4j.rootLogger=INFO, file, stdout

# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=logging.log
log4j.appender.file.MaxFileSize=10MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

**UPDATE: **

when I open the jar using WinRar it shows me that it contains the log4j.properties and log4j jar so it s not a resources problem!

Answer 1

first of ALL: It called: log4j.properties not Log4j.properties !!

Second: instead of PropertyConfigurator.configure("log4j.properties"); it should be: PropertyConfigurator.configure(getClass().getResource("/log4j.properties"));

Answer 2

Check your resource directory in maven build. It should be something like this.

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
.......
     <build>
        <resources>
            <resource>
                <directory>src/main/resources</directory>
            </resource>
        </resources>
     </build>
</project>

This way log4j.properties file will be in the classpath directory.
