public static List<List<Object>> read2007Excel(File file) throws FileNotFoundException, IOException
{
List<List<Object>> list =new LinkedList<List<Object>>();
FileInputStream fs = new FileInputStream(file);
XSSFWorkbook xwb = new XSSFWorkbook(fs);
//得到Excel工作表对象
XSSFSheet sheet=xwb.getSheetAt(0);
//获取行对象
XSSFRow row=null;
//获取单元格对象
XSSFCell cell=null;
Object object="";
for(inti=sheet.getFirstRowNum()i<sheet.getPhysicalNumberOfRows();i++)
{
row=sheet.getRow(i);
if(row==null)
{
continue;
}
List<Object> linked = new LinkedList<Object>();
for(int j= 0; j < row.getLastCellNum();j++)
{
cell=row.getCell(j);
if(cell==null)
{
continue;
}

object=cell.toString();
linked.add(object);
System.out.print(object+" ");
}
System.out.println();
list.add(linked);
}

return list;

你不是读取excel2007么，怎么不是.xlsx文件而是.tmp文件啊。。
