英文:
Unable to separate log file on Log4J2
问题
以下是翻译好的内容：
我想要根据我提供的RequestId来分离日志，每个线程一个日志文件。
然而，有一个我不知道的问题。也许，我犯了错误。
无法创建文件 C:\XXXX\XXXXXX\XXXX\logs${ctx:RequestId}.log，java.io.IOException: 文件名、目录名或卷标语法不正确
在 java.io.WinNTFileSystem.canonicalize0(Native Method)
在 java.io.WinNTFileSystem.canonicalize(WinNTFileSystem.java:428)
在 java.io.File.getCanonicalPath(File.java:618)
在 java.io.File.getCanonicalFile(File.java:643)
在 org.apache.logging.log4j.core.util.FileUtils.makeParentDirs(FileUtils.java:142)
这是我的 log4j.xml 配置文件：
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="debug">

<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern=""/>
</Console>

I would like to separate logs with each thread which I gave as RequestId.
However, there is a problem I do not know. Maybe, I made mistake/s.
Unable to create file C:\XXXX\XXXXXX\XXXX\logs${ctx:RequestId}.log java.io.IOException: The filename, directory name, or volume label syntax is incorrect
