javaweb之動態讀excel，導入excel，poi，jxl 支持判斷2003.2007及以上
今天發現以前的那個導入有問題，只是支持2003，並無支持2007及以上版本。poi 是支持目前excel的全部
java
版本的。只不過不一樣版本所使用的讀取方法名不同excel
也是發現網上不少的都是博文都是沒有判斷版本的，包括我以前借鑑的文章。code
File file = new File(path); getData(file, 0); //path是路徑，
重要代碼orm
public String[][] getData(File file, int ignoreRows)
throws FileNotFoundException, IOException {
List<String[]> result = new ArrayList<String[]>();
int rowSize = 0;
BufferedInputStream in = new BufferedInputStream(new FileInputStream(
file));
// 打開HSSFWorkbook
// POIFSFileSystem fs = new POIFSFileSystem(in);
// HSSFWorkbook wb = new HSSFWorkbook(fs);
// HSSFCell cell = null;
// HSSFWorkbook:是操做Excel2003之前（包括2003）的版本，擴展名是.xls
// XSSFWorkbook:是操做Excel2007的版本，擴展名是.xlsx
// Workbook wb = null;
int excel=0;
InputStream inp= in;
if(! inp.markSupported()) {
inp = new PushbackInputStream(inp, 8);
}
if(POIFSFileSystem.hasPOIFSHeader(inp)) {
System.out.println("2003及如下");
excel=2;
}
if(POIXMLDocument.hasOOXMLHeader(inp)) {
System.out.println("2007及以上");
excel=3;
}
// if (!path.endsWith(".xls")) {
// excel =1;
// }
