Grails：如何从控制器或服务访问i18n？ [英] Grails: How to access i18n from controller or service?

问题描述

我制作了这个控制器，它应该用来发送电子邮件。我需要访问i18n才能发送本地化的电子邮件。

  class MailController {
 
 MessageSource message $ 
 
 static transactional = false 
 
 public void sendEmail（）{
 String name =some name ...
 String subject = message（code：somemessagekey，args：[name]）
 //在这里做一些花哨的东西... 
 
 
  

然后是i18n文件（位于i18n文件夹中）：

 文件名：messages.properties 
内容： somemessagekey = Blabla {0}  -  blablabla 
  

运行这个之后，它会抛出（在集成测试中） ：

  groovy.lang.MissingPropertyException：没有这样的属性：class的messageSource：org.codehaus.groovy.grails.support.MockApplicationContext 
  

我不知道如何处理控制器中的本地化（我也在服务中尝试过，但是这更复杂）。

  def messageSource 
  

这样它就会被注入到你的控制器中。我认为在2.0版中，您可以按照您发布的方式进行操作，但即使如此，我认为还是值得尝试按照上述说明。

I have made this controller, which should be used to send emails. I need to access i18n in order to send localized emails.

class MailController {

    MessageSource messageSource 

    static transactional = false

    public void sendEmail() {
        String name = "some name..."
        String subject = message(code:"somemessagekey", args:[name])
        // do some fancy stuff here...
    }
}

There is the i18n file then (located in i18n folder):

file name: messages.properties
content: somemessagekey = Blabla {0} - blablabla

After I run this, it throws (in an integration test):

groovy.lang.MissingPropertyException: No such property: messageSource for class: org.codehaus.groovy.grails.support.MockApplicationContext

I am out of ideas how to handle that localization in controller (I also tried it in a service, but that is even more complicated).

解决方案

If you are using grails 1.3.7, you need to declare message source as :

def messageSource

This way it will be injected into your controller. I think in 2.0 you can do it the way you posted, but it even so, I think it is worth a try to declare it as stated above.
