java - BufferSize 在 log4j xml 配置中的位置

Question

我的 log4j.xml 配置中有以下内容:

<appender name="FileAppender" class="org.apache.log4j.DailyRollingFileAppender">
    <param name="File" value="${MDCapture.logfile.dir}/${APP_NAME}.log"/>
    <param name="BufferedIO" value="false"/>
    <param name="DatePattern" value="'.'yyyy-MMM-dd"/>
    <layout class="org.apache.log4j.TTCCLayout">
        <param name="DateFormat" value="ISO8601"/>
    </layout>
</appender>

<appender name="AsyncAppenders" class="org.apache.log4j.AsyncAppender">
    <appender-ref ref="FileAppender"/>
    <param name="BufferSize" value="1000" />
</appender>

当我运行它时，我收到以下警告:

08-Apr-2013 14:22:15 log4j:WARN Continuable parsing error 18 and column 13 log4j:WARN The content of element type "appender" must match "(errorHandler?,param*,rollingPolicy?,triggeringPolicy?,connectionSource?,layout?,filter*,appender-ref*)".

我是否需要如下移动:

<appender name="FileAppender" class="org.apache.log4j.DailyRollingFileAppender">
    <param name="File" value="${MDCapture.logfile.dir}/${APP_NAME}.log"/>
    <param name="BufferedIO" value="false"/>
    <param name="DatePattern" value="'.'yyyy-MMM-dd"/>
    <!-- HERE -->
    <param name="BufferSize" value="1000" /> 
    <!-- END HERE --> 
    <layout class="org.apache.log4j.TTCCLayout">
        <param name="DateFormat" value="ISO8601"/>
    </layout>
</appender>

Answer 1

嗯，我只看到13行代码，但是

<appender name="AsyncAppenders" class="org.apache.log4j.AsyncAppender">
    <appender-ref ref="FileAppender"/>
    <param name="BufferSize" value="1000" />
</appender>

有<appender-ref>和 <param>标签顺序错误。

WARN 元素类型“appender”的内容必须匹配“(errorHandler?,param*,rollingPolicy?,triggeringPolicy?,connectionSource?,layout?,filter*,appender-ref *)".
