在我的项目中，我使用Log4j处理所有日志记录。我使用的配置：
<Appenders>
<Console name="STDOUT" target="SYSTEM_OUT">
<PatternLayout pattern="%d - %-5p %-10c - %m%n"/>
</Console>
<File name="file" fileName="logs/TAF_${sys:current_date}.log">
<PatternLayout>
<Pattern>%d{yyyy-mm-dd_HH:mm:ss.SSS} - %-5p %-10c - %m%n</Pattern>
</PatternLayout>
</File>
</Appenders>
<Loggers>
<Root level="trace">
<AppenderRef ref="file" level="DEBUG"/>
<AppenderRef ref="STDOUT" level="DEBUG"/>
</Root>
</Loggers>
我得到的错误：

第一个错误是在荷兰语中，它翻译为：“文件名，目录名或卷标语法不正确。”
此Log4J配置文件在Ubuntu环境下使用，并且运行良好。现在，我已将Win10计算机添加到池中，但是收到此错误。
我在做什么错了？
我试图将路径设置为绝对路径“ c：/ Project / logs / TAF _ $ {sys：current_date} .log”，但它没有解决问题。每个用户都具有对日志目录的读/写访问权限。
我尝试过的其他东西： Log4j logfile error FileNotFoundException
@edit： 对于我所看到的，似乎log4j试图创建一个名为“ TAF _ $ {sys：current_date} .log”的文件。当然，那是行不通的，因为{和}对文件名无效。删除“ _ $ {sys：current_date}”后，我便可以创建日志文件。如何再次使用该表达式来添加当前日期/时间？
@ edit2：找到了答案here。我需要在代码中设置系统属性“ current_date”。
