不为log4j2添加RollingFile附加符

Question

我正在为我的web应用程序设置log4j2。问题是，这样配置的记录器没有使用Main和Err appender记录任何内容。如果通过调试器查看log4j2代码，就会发现在log4j2初始化期间没有添加这两个附加符。

以前，每个附加程序都有单独的记录器，但我们只需要一个记录器。这样做有可能吗？

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="trace" strict="true" name="log4j2 config">
  <Properties>
    <Property name="dataPattern">%d{yyyy-MM-dd HH:mm:ss,SSS} %-5p %c{3} - %m%n%ex</Property>
    <Property name="logDir">${web:rootDir}</Property>
    <Property name="moduleName">mod</Property>
    <Property name="logLevel">@log.level@</Property>
  </Properties>

  <Filter type="ThresholdFilter" level="all"/>
 <Appenders>
    <Appender type="Console" name="Out">
      <Layout type="PatternLayout" pattern="${dataPattern}"/>
    </Appender>

  <Appender type="RollingFile" name="Main" fileName="${logDir}/${moduleName}_main.log"
                   filePattern="${logDir}/${moduleName}_main.log.%i">
        <Layout type="PatternLayout" pattern="${dataPattern}"/>
        <Policies>
          <SizeBasedTriggeringPolicy size="8 MB"/>
        </Policies>
        <DefaultRolloverStrategy max="10" fileIndex="min"/>
    </Appender>

    <Appender type="RollingFile" name="Err" fileName="${logDir}/${moduleName}_err.log"
                   filePattern="${logDir}/${moduleName}_err.log.%i">
        <Layout type="PatternLayout" pattern="${dataPattern}"/>
        <Filter type="ThresholdFilter" level="error"/>
        <Policies>
          <SizeBasedTriggeringPolicy size="8 MB"/>
        </Policies>
        <DefaultRolloverStrategy max="10" fileIndex="min"/>
    </Appender>
 <Loggers>
      <Logger name="com.dsl.${moduleName}" level="${logLevel}">
          <AppenderRef ref="Main"/>
          <AppenderRef ref="Err"/>
      </Logger>
<Root level="${logLevel}">
        <AppenderRef ref="Main"/>
        <AppenderRef ref="Err">
            <Filter type="ThresholdFilter" level="error"/>
        </AppenderRef>      
    </Root>
  </Loggers>
</Configuration>

错误无法为元素RollingFile调用类class org.apache.logging.log4j.core.appender.RollingFileAppender中的工厂方法。java.lang.IllegalStateException：未找到org.apache.logging.log4j.core.appender.RollingFileAppender类的工厂方法

以及：

ERROR Null object returned for RollingFile in Appenders.
ERROR Null object returned for RollingFile in Appenders.
ERROR Unable to locate appender "Main" for logger config "root"
ERROR Unable to locate appender "Err" for logger config "root"
ERROR Unable to locate appender "Main" for logger config "com.dfs.acs"
ERROR Unable to locate appender "Err" for logger config "com.dfs.acs"

这似乎是Servlet3.0解析${web:rootdir}的问题。
