读取Excel文档时出现问题(Java代码)

我有一些Java代码读取Excel数据。 在运行Java代码时,它显示以下错误。 帮我解决同样的问题。 另外,我需要知道其他读取.xlsx文件的方法。

(小编辑)我如何用各自的列打印行。 例如:

Age 19 20 21 Salary 35k 20k 40k . . . 

线程“main”中的exceptionorg.apache.poi.poifs.filesystem.OfficeXmlFileException:提供的数据似乎位于Office 2007+ XML中。 您正在调用处理OLE2 Office文档的POI部分。 您需要调用POI的不同部分来处理org.apache.poi.poifs.storage中的org.apache.poi.poifs.storage.HeaderBlock。(HeaderBlock.java:131)中的数据(例如XSSF而不是HSSF)。 .HeaderBlock。(HeaderBlock.java:104)org.apache.poi.poifs.filesystem.POIFSFileSystem。(POIFSFileSystem.java:138)org.apache.poi.hssf.usermodel.HSSFWorkbook。(HSSFWorkbook.java:322)在ExcelRead.main的org.apache.poi.hssf.usermodel.HSSFWorkbook。(HSSFWorkbook.java:303)(ExcelRead.java:18)

Java代码如下:

 import java.io.File; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.IOException; import java.util.Iterator; import org.apache.poi.hssf.usermodel.HSSFSheet; import org.apache.poi.hssf.usermodel.HSSFWorkbook; import org.apache.poi.ss.usermodel.Cell; import org.apache.poi.ss.usermodel.Row; public class ExcelRead { public static void main(String[] args) { try { FileInputStream file = new FileInputStream(new File("C:/Users/vinayakp/Desktop/Book.xlsx")); HSSFWorkbook workbook = new HSSFWorkbook(file); HSSFSheet sheet = workbook.getSheetAt(0); Iterator rowIterator = sheet.iterator(); while(rowIterator.hasNext()) { Row row = rowIterator.next(); Iterator cellIterator = row.cellIterator(); while(cellIterator.hasNext()) { Cell cell = cellIterator.next(); switch(cell.getCellType()) { case Cell.CELL_TYPE_BOOLEAN: System.out.print(cell.getBooleanCellValue() + "\t\t"); break; case Cell.CELL_TYPE_NUMERIC: System.out.print(cell.getNumericCellValue() + "\t\t"); break; case Cell.CELL_TYPE_STRING: System.out.print(cell.getStringCellValue() + "\t\t"); break; } } System.out.println(""); } file.close(); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException ae) { ae.printStackTrace(); } } } 

删除previus导入类后,再添加

 import org.apache.poi.ss.usermodel.Cell; import org.apache.poi.ss.usermodel.Row; import org.apache.poi.ss.usermodel.Sheet; import org.apache.poi.ss.usermodel.Workbook; import org.apache.poi.ss.usermodel.WorkbookFactory; private static void read(String path){ Workbook workbook = null; FileInputStream fis = null; try { File source = new File(path); if(source.exists()){ fis = new FileInputStream(source); workbook = WorkbookFactory.create(source); }else{ JOptionPane.showMessageDialog(null, "File path is not exist.", "Error", JOptionPane.ERROR_MESSAGE); } Sheet sheet = null; int lastRowNum = 0; int numSheets = workbook.getNumberOfSheets(); for(int i = 0; i < numSheets; i++) { sheet = workbook.getSheetAt(i); if(sheet.getPhysicalNumberOfRows() > 0) { lastRowNum = sheet.getLastRowNum(); int lastCellNum = 0; for(Row row : sheet) { Employee emp = new Employee(); int numOfCell = row.getPhysicalNumberOfCells(); System.out.println("numOfCell:: "+numOfCell); String stringValues [] = new String[numOfCell]; for(Cell cell : row) { // cell = row.getCell(cellIndex); int cellIndex = cell.getColumnIndex(); logger.info("cellIndex:: "+ cellIndex); switch (cell.getCellType()) { case Cell.CELL_TYPE_FORMULA: // printValue = "FORMULA value=" + cell.getCellFormula(); stringValues[cellIndex] = cell.getCellFormula(); break; case Cell.CELL_TYPE_NUMERIC: //printValue = "NUMERIC value=" + cell.getNumericCellValue(); System.out.println("Value is numeric:: "+ cell.getNumericCellValue()); stringValues[cellIndex] = String.valueOf(cell.getNumericCellValue()); break; case Cell.CELL_TYPE_STRING: // printValue = "STRING value=" + cell.getStringCellValue(); stringValues[cellIndex] = cell.getStringCellValue(); break; case Cell.CELL_TYPE_BLANK: // printValue = "STRING value=" + cell.getStringCellValue(); stringValues[cellIndex] = cell.getStringCellValue(); break; default: } } } } } } } catch (InvalidFormatException e) { logger.error(e.getMessage()); e.printStackTrace(); } catch (FileNotFoundException e) { e.printStackTrace(); logger.error(e.getMessage()); } catch (IOException e) { logger.error(e.getMessage()); e.printStackTrace(); } catch (Exception e) { logger.error(e.getMessage()); e.printStackTrace(); } finally { if (fis != null) { try { fis.close(); fis = null; } catch (IOException ioEx) { logger.error(ioEx.getMessage()); } } } } 

如果要读取.xls文件,则必须使用HSSF (它仅支持.xls格式),但对于.xlsx文件,必须使用XSSF或其他更高版本的API。

您正在使用错误的类来读取文件HSSFWorkbook是用于旧的Excel格式。 请改用XSSFWorkbook

 try { System.out.println("destDir==> "+destDir); XSSFWorkbook workBook = new XSSFWorkbook(destDir); XSSFSheet sheet = workBook.getSheetAt(0); totalRows = sheet.getPhysicalNumberOfRows(); System.out.println("total no of rows >>>>"+totalRows); } catch (IOException e) { e.printStackTrace(); }
