从Excel

Question

我的代码如下：

public class DataHelper {
     public static List<HashMap<String,String>> data(String filepath,String sheetName) {
          List<HashMap<String,String>> mydata = new ArrayList<>();
          try {
             FileInputStream fs = new FileInputStream(filepath);
             XSSFWorkbook workbook = new XSSFWorkbook(fs);
             XSSFSheet sheet = workbook.getSheet(sheetName);
             //System.out.println(sheet.getLastRowNum()+"total no of row");
             Row HeaderRow = sheet.getRow(0);
             //System.out.println(sheet.getPhysicalNumberOfRows()+"get the total no of rows");
             for(int i=1;i<sheet.getPhysicalNumberOfRows();i++) {
                 Row currentRow = sheet.getRow(i);
                 HashMap<String,String> currentHash = new HashMap<String,String>();
                 //System.out.println(currentRow.getPhysicalNumberOfCells());
                 for(int j=0;j<currentRow.getPhysicalNumberOfCells();j++) {
                     Cell currentCell = currentRow.getCell(j);
                     switch (currentCell.getCellType()) {
                         case Cell.CELL_TYPE_STRING:
                         //      
                             currentHash.put(HeaderRow.getCell(j).getStringCellValue(), currentCell.getStringCellValue());

                         case Cell.CELL_TYPE_Numeric:
                             currentHash.put(HeaderRow.getCell(j).getStringCellValue(), currentCell.getStringCellValue());
                             break;  
                     }
                 }
                 mydata.add(currentHash);
             }
             fs.close();
          }
          catch (Exception e)
          {
             e.printStackTrace();
          }
          return mydata;
       }

在上面的代码中，当从excel表传递整数值时，它将它转换为double，因为我使用带有字符串参数的hashmap，我不能使用integer.parseint。那么如何将double值转换为int？

感谢。

如果您不想依赖于getCellStringValue上的Excel / POI格式，请执行以下操作：

    break;
case Cell.CELL_TYPE_Numeric:
    double x = currentCell.getNumericCellValue();
    //String value = Double.toString(x);
    String value = Long.toString(Math.round(x));
    currentHash.put(HeaderRow.getCell(j).getStringCellValue(), value);
    break;
