Question

我想根据我指定的仅记录器名称将消息记录到文件中，因为记录器名称作为日志消息中的参数发送。默认情况下，无论记录器名称如何，我的所有日志文件都会被附加，因为我在root下添加了所有appender的ref。

我的log4j.xml如下所示。

<?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="ImmediateFlush" value="true" />
    <param name="Append" value="true" />
    <param name="File" value="C:/SSG_Admin.log" />
    <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">
    <param name="ImmediateFlush" value="true" />
    <param name="Append" value="true" />
    <param name="File" value="C:/SSG_Security.log" />
    <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="application_log" class="org.apache.log4j.DailyRollingFileAppender">
    <param name="ImmediateFlush" value="true" />
    <param name="Append" value="true" />
    <param name="File" value="C:/SSG_Core.log" />
    <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-ref ref="operator_log" />
    <appender-ref ref="security_log" />
    <appender-ref ref="application_log" />
</root>

记录器下的指定appender只能为我附加相应的文件。但是，无论记录器名称如何，所有文件都会被追加。我对记录器很新。有没有解决方案......

请您查看＆＃34;类别＆＃34;？以下是一个例子：

<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>

根据log4j.xml中的记录器名称记录到不同的文件
