在域对象和静态范围中获取 grails 2.0.0M1 配置信息? [英] getting grails 2.0.0M1 config info in domain object, and static scope?

问题描述

如何从域对象或静态范围获取 Config.groovy 信息?我现在正在使用 ConfigurationHolder.config.*，但不推荐使用它和 ApplicationHolder，所以我想做对了"......但是 grailsApplication 对象在 DO/静态范围内不可用.

How do I get to the Config.groovy information from a domain object, or from a static scope? I'm using ConfigurationHolder.config.* now, but that and ApplicationHolder are deprecated so I'd like to 'do it right' ... but the grailsApplication object isn't available in a DO/static scope.

推荐答案

我会将 grailsApplication 添加到域类的元类中 - 这是我正在考虑为 2.0 final 做的事情.现在，把它放在 BootStrap.groovy 中，例如

I'd add the grailsApplication to the metaclass of domain classes - this is something I'm thinking about doing for 2.0 final. For now, put it in BootStrap.groovy, e.g.

class BootStrap {

   def grailsApplication

   def init = { servletContext ->
      for (dc in grailsApplication.domainClasses) {
         dc.clazz.metaClass.getGrailsApplication = { -> grailsApplication }
         dc.clazz.metaClass.static.getGrailsApplication = { -> grailsApplication }
      }      
   }
}

然后你可以从 grailsApplication.config 访问配置，通过 grailsApplication.mainContext.getBean('foo') 或 grailsApplication.mainContext 访问 Spring bean.foo.

Then you can access the config from grailsApplication.config, and Spring beans via grailsApplication.mainContext.getBean('foo') or just grailsApplication.mainContext.foo.
