Question

我有一个类为我解析xsl文件并用xsl的头部映射它。

我有另一个类，它是xsl每行的对象，并使用标题来知道哪个单元格通过我之前映射的标题获取哪个属性...

由于某些原因我在其中一个标题上出现错误NoSuchElementException，并且没有拼写错误...它之前有效，我现在不知道什么是错的。

这是控制xsl：

的DataSource.scala类（它的特性）

import java.io.File

import com.github.tototoshi.csv.CSVReader
import jxl.{Cell, Workbook}

import scala.collection.mutable

trait DataSource {

  def read (fileName: String): Seq[Map[String, String]]
}



object CsvDataSource extends DataSource {
  import com.github.tototoshi.csv.CSVFormat
  import com.github.tototoshi.csv.Quoting
  import com.github.tototoshi.csv.QUOTE_MINIMAL

  implicit object VATBoxFormat extends CSVFormat {
    val delimiter: Char = '\t'
    val quoteChar: Char = '"'
    val escapeChar: Char = '"'
    val lineTerminator: String = "\r\n"
    val quoting: Quoting = QUOTE_MINIMAL
    val treatEmptyLineAsNil: Boolean = false
  }

  override def read(file: String): Seq[Map[String, String]] = {
    val reader = CSVReader.open(file, "UTF-16")(VATBoxFormat)
    reader.readNext()
    val country = reader.readNext().get(5)
    reader.readNext()
    reader.iteratorWithHeaders.toSeq.map(c => c + ("country" -> country))
  }
}

object ExecDataSource extends DataSource {
  override def read(file: String): Seq[Map[String, String]] = {
    val workbook = Workbook.getWorkbook(new File(file))
    val sheet = workbook.getSheet(0)

    val rowsUsed: Int = sheet.getRows

    val headers = sheet.getRow(3).toList
    //    println(headers.map(_.getContents))
    val country = sheet.getCell(5, 1).getContents

    (4 until rowsUsed).map { i =>
      val c = headers.zip(sheet.getRow(i)).map{case (k,v) => (k.getContents, v.getContents)}.toMap
      c + ("country" -> country)
    }
  }
}

这是PurchaseInfo类，它正在创建excel的每一行的对象：

case class PurchaseInfo(
                         something1: String,
                         something2: String,
                         something3: String,
                         something4: String) {
}


object PurchaseInfo {

    private def changeDateFormat(dateInString: String): String = {
    //System.out.println(dateInString)
    val formatter: SimpleDateFormat = new SimpleDateFormat("MMM dd, yyyy")
    val formatter2: SimpleDateFormat = new SimpleDateFormat("dd/MM/yyyy")
    val date: Date = formatter.parse(dateInString)
    return formatter2.format(date).toString
  }

    def fromDataSource (ds: DataSource)(fileName: String): Seq[PurchaseInfo] = {

      ds.read(fileName).map { c =>
        PurchaseInfo(
          something1 = c("Supplier Address Street Number"),
          something2 = c("Supplier Address Route"),
          something3 = c("Supplier Address Locality"),
          something4 = c("Supplier Address Postal Code")
        )
      }
    }
}

（iv在buyInfo中删除了一些var以使问题更短）

现在，这是我在运行代码时遇到的错误（来自运行我的操作的diff类，这是一个我使用selenium的自动化项目）

有人能看到这个问题......？我不知道为什么他找不到＆＃34;供应商地址街道号码＆＃34;，在xsl我有这个标题完全一样：/
