在脚本中使用Grails服务 [英] Using a Grails service inside a script

问题描述

  includeTargets<<< p> grailsS​​cript（_ GrailsInit）
 
 target（loadGames：脚本描述在这里！）{
 def listFile = new File（'list.txt'）
 
 listFile.eachLine {
 def result = ctx.getBean（bggService）。search（it）
 println it ++ result.length（）
} 
 
 $ b $ setDefaultTarget（loadGames）
  

我见过十几个不同的网页，每个网页提供了 ctx appCtx 和 applicationContext （以及许多其他）作为建议，但是它们都不起作用。通常他们会抱怨我试图使用的上下文变量不存在。

为什么Grails不能在脚本中使用服务，方式与他们完全相同

在Grails脚本中使用Grails服务的正确方法是什么？

解决方案

通过 ApplicationContext 和 grailsApplication http://grails.org/doc/2.3.x/ref/Command%20Line/bootstrap.htmlrel =nofollow> bootstrap 命令。包括 _GrailsBootstrap 脚本，然后调用 configureApp（）或依赖它以使 ApplicationContext 可在脚本中找到：

  includeTargets<< grailsS​​cript（_ GrailsInit）
 includeTargets<< grailsS​​cript（_ GrailsBootstrap）
 
 target（loadGames：脚本描述在这里！）{
 depends（configureApp）
 
 def listFile = new文件（'list.txt'）
 
 listFile.eachLine {
 //一旦configureApp（）调用ApplicationContext可以作为appCtx访问
 def result = appCtx.getBean（bggService ）.search（it）
 println it ++ result.length（）
} 
} 
 
 setDefaultTarget（loadGames）
  




I'm trying to use a Grails service inside the following Grails script

includeTargets << grailsScript("_GrailsInit")

target(loadGames: "The description of the script goes here!") {
   def listFile = new File('list.txt')

   listFile.eachLine {
      def result = ctx.getBean("bggService").search(it)
      println it + " " + result.length()
   }
}

setDefaultTarget(loadGames)

I've seen about a dozen different webpages each offering a different combination of ctx appCtx, and applicationContext (as well as many others) as suggestions, however none of them work. Typically they complain that the context variable that I am trying to use does not exist.

Why can't Grails just use services inside a script in exactly the same way that they get used in controllers?

What is the right way to use a Grails service inside a Grails script?

解决方案

Getting hold of ApplicationContext and grailsApplication is possible though bootstrap command. Include _GrailsBootstrap script, then call configureApp () or depend on it in order to make ApplicationContext available in script:

includeTargets << grailsScript("_GrailsInit")
includeTargets << grailsScript("_GrailsBootstrap")

target(loadGames: "The description of the script goes here!") {
   depends(configureApp)

   def listFile = new File('list.txt')

   listFile.eachLine {
      //Once configureApp() called ApplicationContext can be accessed as appCtx
      def result = appCtx.getBean("bggService").search(it)
      println it + " " + result.length()
   }
}

setDefaultTarget(loadGames)
