Grailsのブートストラップや仕事

Question

から呼び出されたときにエラーを与えて3メールプラグインのHTMLビューには、私は、電子メールテンプレートがgrails-app/view/email/expiry.gspであるGrailsのメールプラグイン

@Transactional 
@Slf4j 
class ExpireAlertService { 
    def mailService 
... 
... 
    void sendExpiryMails() { 

     def list = SomeDomain.list() 
     list.each { 
      log.debug('Sending Mail {}', it.id) 

      mailService.sendMail { 
       to 'to@somedomain.com' 
       from 'sender@mydomain.com' 
       subject "Expiry Alert !!!" 
       html view: "/email/expiry", model: [ 
         id    : id, 
         ... 

       ] 
      } 
     } 
    } 
} 

を使用してサービスを提供しています。このサービスがコントローラに注入され、何らかのアクションから呼び出されると、期待どおりに動作し、メールが送信されます。同サービスはBootstrap.groovyまたはスケジュールされたジョブで注入されたとき、それは例外がhtml view:"/email/expiry"ラインで発生

を実行したときしかし、私はこの例外を取得します。コントローラ以外のユースケースからのgspビューを解決するために必要なことはありますか？

私はすべてのヘルプは大歓迎ですorg.grails.plugins:mail:2.0.0.RC4

のGrails 3.1.1とメールプラグインを使用しています。

Answer 1

このエラーは、serverUrlが設定されていない場合に発生します。

def grailsApplication // injected 
... 
LinkGenerator grailsLinkGenerator = grailsApplication.mainContext.getBean("grailsLinkGenerator") 
grailsLinkGenerator.configuredServerBaseURL ?: grailsApplication.config.grails.serverUrl 

これはグローバルなものを設定しなくても当たり、環境ごとに設定SERVERURLを伝播：私のBootstrap.groovyでは、私はこれを使用しています。
