java怎么利用map和list把excel中的表格中的数据输出到控制台？

求具体实现代码

Excel解析，2层for循环输出，Excel 2003用 jxl解析，2003以后用poi解析。

private void readBatchFile()
throws Exception {
File file = new File("C:\Users\Administrator\Desktop\test.xlsx");
InputStream in = new FileInputStream(file);
Workbook wb = WorkbookFactory.create(in);
Sheet sheet = wb.getSheetAt(0);
int rowNum = 1;
while (true) {
Row row = sheet.getRow(rowNum++);
if (row == null)
break;
Cell cell = row.getCell(0);
if (cell == null || StringUtils.isBlank(cell.getStringCellValue())) {
break;
}
int n = 0;
Cell c;
for(int i=0;i<10;i++){
c = row.getCell(i);
if (c != null) {
c.setCellType(Cell.CELL_TYPE_STRING);
String s = c.getStringCellValue();
System.out.println("第"+rowNum+"行，第"+i+"列数据："+s);
}
}

    }
}


    依赖jar包 :

poi-3.13.jar
poi-ooxml-3.13.jar
poi-ooxml-schemas-3.13.jar
xmlbeans-2.6.0.jar
