启动时log4j报错，log4j应该怎么配置

<appender name="avatarAppender" class="org.apache.log4j.DailyRollingFileAppender">
    <param name="File" value="/data/applogs/tpfun-dealDuplicateCheck-job/logs/avatar.log" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="[tpfun-dealDuplicateCheck-job]%d %-5p [%c] %m%n" />
    </layout>
</appender>

<appender name="appAppender" class="org.apache.log4j.DailyRollingFileAppender">
    <param name="File" value="/data/applogs/tpfun-dealDuplicateCheck-job/logs/app.log" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="[tpfun-dealDuplicateCheck-job]%d %-5p [%c] %m%n" />
    </layout>
</appender>

<appender name="ibatisAppender" class="org.apache.log4j.DailyRollingFileAppender">
    <param name="File" value="/data/applogs/tpfun-dealDuplicateCheck-job/logs/ibatis.log" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="[tpfun-dealDuplicateCheck-job]%d %-5p [%c] %m%n" />
    </layout>
</appender>

<logger name="com.dianping.avatar" additivity="false">
    <appender-ref ref="CONSOLE" />
    <appender-ref ref="avatarAppender" />
</logger>

<logger name="com.ibatis" additivity="false">
    <level value="WARN" />
    <appender-ref ref="ibatisAppender" />
</logger>

<logger name="java.sql">
    <level value="WARN" />
</logger>

<logger name="org.springframework.jms">
    <level value="ERROR" />
</logger>

<logger name="org.springframework.context">
    <level value="INFO" />
    <appender-ref ref="CONSOLE" />
    <appender-ref ref="appAppender" />
</logger>

<root>
    <level value="INFO" />
    <appender-ref ref="CONSOLE" />
    <appender-ref ref="appAppender" />
</root>

这是我的配置文件，报错为
log4j:WARN Fatal parsing error 2 and column 72
log4j:WARN 在 publicId 和 systemId 之间需要有空格。
log4j:ERROR Could not parse url [file:/D:/workspace/tpfun-job/tpfun-dealDuplicateCheck-job/target/classes/log4j.xml].
org.xml.sax.SAXParseException; systemId: file:/D:/workspace/tpfun-job/tpfun-dealDuplicateCheck-job/target/classes/log4j.xml; lineNumber: 2; columnNumber: 72; 在 publicId 和 systemId 之间需要有空格。

解决方案

你贴的这个配置文件 没有publicId 和 systemId ，怎么就报log4j:WARN 在 publicId 和 systemId 之间需要有空格，让人怎么解决
