在groovy类中访问grailsApplication或Service

问题描述

我试图在 依赖注入不适用于 src下的常规类/常规。您可以像这样使用 ApplicationHolder 访问 grailsApplication 。

  import org.codehaus.groovy.grails.commons.ApplicationHolder 
 $ b $ def grailsApplication = ApplicationHolder.application 
  

您可以像这样访问所有服务：

  def allServicesArtefacts = grailsApplication.services 
  

I am trying to access grailsApplication in groovy class under src/groovy but I get a null pointer exception. I also tried to inject a service into the same class and same result. How can I access grailsApplication or a service from groovy class? (I am using Grails 1.3.7)

解决方案

Dependency injection does not work for groovy classes under src/groovy. You can get the access to grailsApplication using ApplicationHolder like this:

import org.codehaus.groovy.grails.commons.ApplicationHolder

def grailsApplication = ApplicationHolder.application

You can access all services like this:

def allServicesArtefacts = grailsApplication.services
