异步Logger Log4j2：异步和同步混合

Question

我通过使用-DLog4jContextSelector = org.apache.logging.log4j.core.async.AsyncLoggerContextSelector -DAsyncLogger.RingBufferSize = 524288尝试了异步记录器 系统属性和异步记录器正常运行，但是当我删除系统属性并使用xml配置时，似乎记录器未配置为异步记录器，而是普通记录器。 在使用xml配置Async记录器时需要帮助，以便可以同步配置某些记录器，而另一些可以配置为Async。

<Configuration status="debug">
    <Appenders>
        <Console name="Console-Appender" target="SYSTEM_OUT" >
            <PatternLayout>
                <pattern>
                    [%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
                </pattern>>
            </PatternLayout>
        </Console>        
        <RollingRandomAccessFile name="Rolling-Random-Access-File-Appender"

                                  immediateFlush="false" append="false">
