Java Log4j2登录到用户主文件夹

我试图将log4j2日志保存到用户主文件夹中，因为用户无权写入应用程序的安装位置

这是我的log4j设置的相关部分。不幸的是，它没有解析user.home，因此它创建了应用程序正在运行的文件夹$user.home

有办法解决这个问题吗？

我解决了这个问题。您应该使用

${sys:user.home}

而不是

${user.home}

<appenders>
    <appender name="Console" type="Console" target="SYSTEM_OUT">
        <layout type="PatternLayout" pattern="${patternlayout}" />
    </appender>

    <!-- Log su file ogni giorno, e mantenimento degli ultimi 5 files -->
    <RollingFile name="File" fileName="${filename}" filePattern="${filenamePattern}" bufferedIO="true" immediateFlush="true" append="true">
        <PatternLayout pattern="${patternlayout}" />
        <Policies>
            <TimeBasedTriggeringPolicy />
        </Policies>
        <DefaultRolloverStrategy>
            <Delete basePath="${user.home}/niro/logs" maxDepth="2">
                <IfFileName glob="niroDesk*.log.gz" />
                <IfLastModified age="7d" />
            </Delete>
        </DefaultRolloverStrategy>
    </RollingFile>

    <appender name="AsyncFile" type="async" blocking="true" bufferSize="128">
        <appender-ref ref="File" />
    </appender>
</appenders>
<loggers>
    <root level="error">
