我们使用grails.config.locations从应用程序外部的文件中提取（可选）设置。有没有一种很好的方法来检测这个文件是在Bootstrap.groovy中还是在Config.groovy本身中加载的？
Config.groovy有这个：
<html>
<head>
<link type="text/css"rel="stylesheet" href="stylesheet.css">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
<title> Comment Post </title>

blank_field = true;

很高兴知道Grails是否在此文件中找到并阅读。
答案 0 :(得分：0)
您可能会在启用Grails调试模式时看到此信息，但您不想这样做。我正在使用以下策略。首先，我检查文件是否存在：
def externalConfigFile = "${userHome}/.grails/${appName}-config.groovy"
if (new File(externalConfigFile).exists()) {
grails.config.locations << "file:" + externalConfigFile
log.info "External configuration file found at ${externalConfigFile} ..."
}
然后在文件中我只记录它已运行：
log.info 'External config file was loaded.'
所以现在我可以在启动日志中看到我找到了一个外部配置文件，它是一个现有文件，该文件是由Grails运行的，所以它被加载了。
我还没有找到更好的东西。
