我正在使用grails「Promise」API來運行線程。在grails中運行線程groovy

線程正在執行以下操作

csv.splitEachLine(',') { row -> 
       insertRecord = Code.findByAni(row[0]) ?: new SurveyProActive(
         cid: row[1], 
         ani: row[0], 
         data_time: new Date(), 
         dnis: Code2.findById((Long) row[2])?.dialNumber, 

       ).save(failOnError: true, flush: true) 
      } 
     }

我只是沒有得到如何解決我所面臨的問題。

無論如何，我得到以下例外

你是如何制定你的承諾的？ 'Promises.task {}'或'Domain.async.task {}' –

Promise.task {//我的代碼 } –

時退房「多個異步調用格姆」一節在這裏：http://docs.grails.org/latest/guide/async.html#asyncGorm。它說Domain.async.task{}處理將新會話綁定到異步線程，而Promises.task不會。

如果你不能使用Domain.async.task{}你也可以嘗試Domain.withNewSession{}方法。
