使用scala关闭drools会话时数据丢失

我有一个应用程序，它是用kiesessionstatefull对象创建的，它处理规则，并将结果生成到迭代器中。但是，当我试图在处理完会话后返回结果时，我面临着一些问题

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，我如何处理/关闭连接而不丢失

processedData

。我们可以为上述迭代器设置（scala）急切加载吗

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
}

以下是错误桩跟踪：-

你面临什么问题？你失去了什么连接？@EstebanAliverti:是的，在kiesession中面临连接失败的问题<代码>java.lang.IllegalStateException:非法方法调用。此会话以前已被释放。没有堆栈跟踪，也不知道您的

getDataModels（）

方法在做什么，这对您很难有帮助。@EstebanAliverti我添加了堆栈跟踪详细信息
