logback groovy中的變量替換

Question

我正在使用logback.xml，並且變量以類似以下的字符串加載：

<FileNamePattern>${logDirectory}/${logFileName}.%d{yyyy-MM-dd}.%i.html</FileNamePattern>

在調用我的jar之前，在.bat文件中設置了logDirectory和logFileName的位置。

set logFileName=foobar

但是現在，我處理了常規問題。 它很棒，而且比xml更可讀。 但是變量不再擴展。

appender("FILE", RollingFileAppender) {
file = "${logDirectory}/${logFileName}.html"
    rollingPolicy(TimeBasedRollingPolicy) {
        fileNamePattern = "${logDirectory}/${logFileName}.%d{yyyy-MM-dd}.%i.html"
        ...
    }
...
} 

路徑現在為null/null ：'（

最壞：以下測試引發異常：

if ("${logConsole}" == "true") {

有人看到如何使它起作用嗎？

-編輯添加完整的logback.groovy

/*
 * The configuration use the following variables :
 * logDirectory => The log folder
 * logFileName => The log file name
 * logConsole => true console activation.

logger("org", INFO)
logger("net", INFO)
logger("freemarker", INFO)

// We don't care about the bean creation at least it's more than a warn
logger("org.springframework.beans.factory", WARN)

root(OFF, ["FILE"])

if (LOG_CONSOLE == "true") {
    root(OFF, ["FILE","STDOUT"]);
}

System.getProperty()調用將檢索在Java命令行上使用-D設置的屬性，而在.bat文件中，您將設置外殼程序/環境變量。

嘗試在logback.groovy文件中使用System.getenv() 。
