java - 发出 http ://apache. org/xml/features/xinclude testing log4j 2

Question

我正在测试 Log4j2，但我不知道自己做错了什么，因为我从 Apache 下载了库并将它们放在了类路径中。我也添加了 xercesImpl、xalan、xml-apis、serializer、xsltc，但异常仍然存在。我显示堆栈跟踪和配置文件:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="DEBUG">
    <Properties>
        <Property name="log-path">C:/Logs/</Property>
    </Properties>
    <Appenders>
        <RollingFile name="RollingFile" fileName="${log-path}/myexample.log"
            filePattern="${log-path}/myexample-%d{yyyy-MM-dd}-%i.log">
            <PatternLayout>
                <pattern>%d{dd/MMM/yyyy HH:mm:ss,SSS}- %c{1}: %m%n</pattern>
            </PatternLayout>
            <Policies>
                <SizeBasedTriggeringPolicy size="1 KB" />
            </Policies>
            <DefaultRolloverStrategy max="4" />
        </RollingFile>
    </Appenders>
    <Loggers>
        <Logger name="root" level="debug" additivity="false">
            <appender-ref ref="RollingFile" level="debug" />
        </Logger>
        <Root level="debug" additivity="false">
            <AppenderRef ref="RollingFile" />
        </Root>
    </Loggers>
</Configuration>

就我而言，从类路径中删除过时的 xercesImpl-2.6.2.jar 会有所帮助。
