How can I get log4j to use a log4j.xml file and not write to console when using Spring?

I'm helping a friend with a project. He uses Spring; I am not. I gave him a log4j.xml file I use to enable logging to a file in a logs/ subdirectory. He tried the log4j.xml but his app is ignoring it (doesn't react to its presence or absence), sending output to the console. It appears Spring is auto-configuring log4j to do this. We also tried -Ddebug.log4j=true to find discern more about log4j's initialization when Spring is involved, but that parameter had no effect.

By default, log4j doesn't make any assumptions about its configuration, it definitely expects either a configuration file or a programmatic configuration.

It scans through the classpath for log4j.properties or log4j.xml. If you prefer a different path and different name, you need pass a system variable something like -Dlog4j.configuration=relative_path_to_file.xml

Right now in our project

we use below xml file

<appender name="EvolutionWebASYNC" class="org.apache.log4j.AsyncAppender">
    <appender-ref ref="logFileOut" />
</appender>

<appender name="logFileOut" class="org.apache.log4j.RollingFileAppender">
    <param name="File" value="C:/home/wasadmin/applogs/myproject/myproject.log" />
    <param name="Append" value="true" />
    <param name="Threshold" value="ALL" />
    <param name="MaxFileSize" value="10MB" />
    <param name="MaxBackupIndex" value="5" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern"
            value="%d %-5p - [TXID: %X{TXID}] [UID: %X{UID}] [ORGOID: %X{ORGOID}] [UA_ORGOID: %X{UA_ORGOID}] - %m%n" />
    </layout>
</appender>

<appender name="console" class="org.apache.log4j.ConsoleAppender">
    <param name="Target" value="System.out" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern"
            value="%d %-5p - [TXID: %X{TXID}] [UID: %X{UID}] [ORGOID: %X{ORGOID}] [UA_ORGOID: %X{UA_ORGOID}] - %m%n" />
    </layout>
</appender>

<root>
    <level value="DEBUG" />
    <appender-ref ref="EvolutionWebASYNC" /> 
</root>

I hope it helps !!!
