根据log4j.xml中的记录器名称登录到不同的文件

Question

我想只根据我指定的记录器名称将消息记录到文件中，因为记录器名称是作为日志消息中的参数发送的。默认情况下，所有日志文件都会被追加，而与记录器名称无关，因为我在根目录下添加了所有追加器的ref。

我的log4j.xml如下。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration debug="true">
<!-- ========== appenders start here ========= -->

<appender name="operator_log" class="org.apache.log4j.DailyRollingFileAppender">

    <param name="DatePattern" value="'.'yyyy-MM-dd" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%d{DATE}|%5p|%m%n" />
    </layout>
</appender>

<appender name="security_log" class="org.apache.log4j.DailyRollingFileAppender">

    </layout>
</appender>

记录器下的指定附加器只应该为我附加相应的文件。但是，所有文件都会被附加，而不管记录器名称如何。我对记录器很陌生。有什么解决方案吗...

你能查一下“类别”吗？以下是一个示例：

<appender name="myFile" class="org.apache.log4j.RollingFileAppender">
    <param name="Threshold" value="INFO" />
    <param name="File" value="/abc/logs/myLog.log"/>
    <param name="Append" value="true" />
    <param name="MaxFileSize" value="10MB" />
    <param name="MaxBackupIndex" value="100" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%r %d %-5p  [%c{1}] %m %n" />
    </layout>
</appender>

<category name="com.myFile.crs" additivity="false">
    <priority value="info" />
    <appender-ref ref="myFile" />
</category>
