excel 2003导入升级到excel 2007

jxl不支持excel 07导入，将POI及jxls升级到较新的版本

 

1.在项目中增加已下jar包：

 

poi-ooxml-3.7.jar

poi-ooxml-schemas-3.7.jar

poi-3.7.jar（替换，将原有poi包删除）

jxls-core-1.0.jar（同上）

jxls-reader-1.0.jar（同上）

commons-jexl-2.1.1.jar（同上）

 

2.修改导入将jxl替换为poi，需使用poi的包

JXL导入

Workbook wb = Workbook.getWorkbook(in);
 Sheet sheet = wb.getSheet(sheetIndex);
 int rows = sheet.getRows(); //多少行
 int cols = sheet.getColumns(); //多少列
 String[][] content = new String[rows - begin][cols];
 for ( int i = begin; i < rows; i++) {
 for ( int j = 0 ; j < cols; j++) {
 Cell cell = sheet.getCell(j, i);
 content[i - begin][j] = cell.getContents();
 }
 }

POI导入

Workbook wb = new XSSFWorkbook(in);
 Sheet sheet = wb.getSheetAt(sheetIndex);
 int rows = sheet.getLastRowNum()+ 1 ; //多少行
 int cols = sheet.getRow(begin).getLastCellNum(); //多少列
 String[][] content = new String[rows - begin][cols];
 Cell tempCell = null ;
 for ( int i = begin; i < rows; i++) {
 Row r = sheet.getRow(i);
 for ( int j = 0 ; j < cols; j++) {
 tempCell = r.getCell(j);
 String str = "" ;
 if (tempCell.getCellType()==HSSFCell.CELL_TYPE_STRING){
 str = tempCell.getStringCellValue();
 } else if (tempCell.getCellType()==HSSFCell.CELL_TYPE_NUMERIC){
 str = String.valueOf(tempCell.getNumericCellValue());
 }
 content[i - begin][j] = str;
 }
 }

3.将模板导出的HSSFWorkbook workbook;改为org.apache.poi.ss.usermodel.Workbook workbook;

原

HSSFWorkbook workbook;
 String templateFileName = sc.getRealPath( "/" ) + templatePath;
 try {
 in = new BufferedInputStream( new FileInputStream(templateFileName));
 XLSTransformer transformer = new XLSTransformer();
 workbook = transformer.transformXLS(in, map);
 OutputStream out = response.getOutputStream();
 workbook.write(out);
 out.flush();

改

org.apache.poi.ss.usermodel.Workbook workbook;
 String templateFileName = sc.getRealPath( "/" ) + templatePath;
 try {
 in = new BufferedInputStream( new FileInputStream(templateFileName));
 XLSTransformer transformer = new XLSTransformer();
 workbook = transformer.transformXLS(in, map);
 OutputStream out = response.getOutputStream();
 workbook.write(out);
 out.flush();

	private static Workbook create(InputStream inp) throws IOException, InvalidFormatException {
		if (!inp.markSupported()) {
			inp = new PushbackInputStream(inp, 8);
		}
		if (POIFSFileSystem.hasPOIFSHeader(inp)) {
			return new HSSFWorkbook(inp);
		}
		if (POIXMLDocument.hasOOXMLHeader(inp)) {
			return new XSSFWorkbook(OPCPackage.open(inp));
		}
		throw new IllegalArgumentException("你的excel版本目前poi解析不了");
	}
