Question

我有一个应用程序，该应用程序是用KieSession状态满对象创建的，并处理规则，并将结果生成到Iterator中。但是，当我处理完同分会话后尝试返回结果时，我遇到了问题。

def ruleExucetion[T](originalData: Iterator[T], drtFile: String ): Iterator[T] = {
 val kSession = getKieSession(drtFile)
 val processedData = getDataModels(kSession, originalData)
 // processedData.size ==> printing the value, but after dispose function, I lost the Iterator data.
 kSession.dispose()
 return processedData
}

在这里，我如何处置/关闭连接而不会丢失processedData。我们可以为上面的Iterator设置（scala）紧急加载吗？

已编辑：

def getDataModels[T](kSession: KieSession, originalData: Iterator[T]): Iterator[T] = {
   val dataModels = originalData.map(dataModel => {
   kSession.insert(dataModel)
   dataModel
  })
  kSession.fireAllRules()
  return dataModels
}

下面是错误放样跟踪：-

ERROR ApplicationMaster: User class threw exception:       java.lang.IllegalStateException: Illegal method call. This session was previously disposed.

使用Scala关闭Drools Kiesession时数据丢失
