Answer 1

尝试使用Apache POI http://poi.apache.org/spreadsheet/index.html

Answer 2

For reading xlsx file we use following jars,

1.dom4j-1.6.1.jar 2.org-apache-commons-codec.jar 3.poi-3.7.jar 4.poi-ooxml-3.5-FINAL.jar 5.poi-ooxml-schemas-3.11-beta2.jar 6.stax-api-1.0.1.jar 7.xmlbeans-2.6.0.jar

This is function through which you can read the the xlsx file.

public static void readXLSX(String path) {
    File file = new File(path);
    String value = "";
    XSSFWorkbook wb = new XSSFWorkbook(new FileInputStream(path));
    XSSFSheet sheet = wb.getSheetAt(0);

    Row row;
    Cell cell;

    Iterator<Row> rowIterator = sheet.iterator();

    while (rowIterator.hasNext()) {
        row = rowIterator.next();
        Iterator<Cell> cellIterator = row.cellIterator();
        while (cellIterator.hasNext()) {
                    cell = cellIterator.next();
                    switch (cell.getCellType()) {
                        case Cell.CELL_TYPE_BOOLEAN:
                            value = "" + cell.getBooleanCellValue();
                            break;
                        case Cell.CELL_TYPE_NUMERIC:
                            value = "" + cell.getNumericCellValue();
                            break;
                        case Cell.CELL_TYPE_STRING:
                            value = "" + cell.getStringCellValue();
                            break;
                        case Cell.CELL_TYPE_BLANK:
                            value = " ";
                            break;
                        default:
                            break;
                    }
                    System.out.println("Value: "+value);
    }

}

Answer 3

The problem is that in Office '07 Microsoft changed its document format to something which is more or less a zip file that contains a large amount of XML. The Java Excel API relies on the old file format. To read something from Office '07, use Apache POI .

Answer 4

1. Don't read Microsoft formats. If you want an excel document read a CSV, comma separated list.
2. Your library doesn't seem to support xlsx
3. Take a look here Choosing an excel java api
