如何在Grails 3中使用外部.groovy配置文件 [英] How to use external .groovy config file in Grails 3

问题描述

第24.3节外部化配置表示 .properties 或 .yml 文件可以用于外部配置，但我希望我的外部配置是 .groovy 文件，就像我的 application.groovy code>我已经从 .yml 转换的文件。我怎么能做到这一点？

Section 24.3 in Externalized Configuration indicates a .properties or .yml file can be used for external config, but I would like my external config to be a .groovy file just like my application.groovy file which I have already converted from .yml. How can I make this happen?

Grails版本3.2.0.M2

我能够根据@Michal_Szulc提供的答案获得此项工作。

I was able to get this working based on the answer provided by @Michal_Szulc

Note that the ConfigSlurper needed the current environment to work correctly.  Also note that these changes are to be made to the my_grails_app/grails-app/init/my_grails_app/Application.groovy file, not the my_grails_app/grails-app/conf/application.groovy file which you may have if you converted from a .yml configuration to a .groovy configuration.

I found this thread and quotation by Graeme Rocher:

Grails 3使用Spring的属性资源概念，因此它将解析
属性从系统，环境和最后的
application.yml / application.groovy

Grails 3 uses Spring's property sources concept, so it will resolve properties from the system, the environment and finally the application.yml/application.groovy

和代码 Clyde Balneaves ：

and code by Clyde Balneaves:

class Application extends GrailsAutoConfiguration implements EnvironmentAware {
    static void main(String[] args) {
    GrailsApp.run(Application)
    }

    @Override
    void setEnvironment(Environment environment) {
    //Set up Configuration directory
    def krakenHome = System.getenv('KRAKEN_HOME') ?: System.getProperty('KRAKEN_HOME') ?: "/opt/kraken"

    println ""
    println "Loading configuration from ${krakenHome}"
    def appConfigured = new File(krakenHome, 'KrakenConfig.groovy').exists()
    println "Loading configuration file ${new File(krakenHome, 'KrakenConfig.groovy')}"
    println "Config file found : " + appConfigured

    if (appConfigured) {
        def config = new ConfigSlurper().parse(new File(krakenHome, 'KrakenConfig.groovy').toURL())
        environment.propertySources.addFirst(new MapPropertySource("KrakenConfig", config))
    }
    }
}
