grails - grails如何在config.groovy之前加载外部配置文件

Question

Grails应用程序基于我的外部属性文件，然后我想在config.groovy(grails.plugins.springsecurity.providerNames)中加载适当的提供程序。这意味着根据外部配置中的属性在config.groovy中进行检查。有没有一种方法可以在config.groovy或其他建议之前加载外部配置？

Answer 1

看看Externalized Configs。特别，

Values that have the same name as previously defined values will overwrite the existing values, and the pointed to configuration sources are loaded in the order in which they are defined.

和 配置默认为

The configuration values contained in the locations described by the grails.config.locations property will override any values defined in your application Config.groovy file which may not be what you want. You may want to have a set of default values be be loaded that can be overridden in either your application's Config.groovy file or in a named config location. For this you can use the grails.config.defaults.locations property.
