java读取xls文件

记录一下，一个简单的读取封装

拿来就能用，返回值是MAP的LIST集合

private static List<HashMap<Object, Object>> getlistitem()
throws IOException {
List<HashMap<Object, Object>> list = new ArrayList<HashMap<Object, Object>>();
File file = new File(
"C:\\Users\\Administrator\\Desktop\\新建文件夹 (4)\\xiugaimiaoshu.xlsx");
InputStream is = new FileInputStream(file);
XSSFWorkbook xssfWorkbook = new XSSFWorkbook(is);
// 获取每一个工作薄
for (int numSheet = 0; numSheet < xssfWorkbook.getNumberOfSheets(); numSheet++) {
XSSFSheet xssfSheet = xssfWorkbook.getSheetAt(numSheet);
if (xssfSheet == null) {
continue;
}
// 获取当前工作薄的每一行
for (int rowNum = 1; rowNum <= xssfSheet.getLastRowNum(); rowNum++) {
XSSFRow xssfRow = xssfSheet.getRow(rowNum);
if (xssfRow != null) {
HashMap<Object, Object> map = new HashMap<Object, Object>();
XSSFCell itemid = xssfRow.getCell(0);
XSSFCell sku = xssfRow.getCell(1);
map.put("sku", sku);
map.put("itemid", itemid);
list.add(map);
}
}
}
return list;
}
