javaweb之动态读excel，导入excel，poi，jxl 支持判断2003.2007及以上

摘要: javaweb之动态读excel，导入excel，poi，jxl 支持判断2003.2007及以上

今天发现之前的那个导入有问题，只是支持2003，并没有支持2007及以上版本。poi 是支持目前excel的所有

版本的。只不过不同版本所使用的读取方法名不一样

也是发现网上很多的都是博文都是没有判断版本的，包括我之前借鉴的文章。

File file = new File(path);
getData(file, 0); //path是路径，

重要代码

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));

// 打开HSSFWorkbook
//		POIFSFileSystem fs = new POIFSFileSystem(in);
//		HSSFWorkbook wb = new HSSFWorkbook(fs);
//		HSSFCell cell = null;

//		HSSFWorkbook:是操作Excel2003以前（包括2003）的版本，扩展名是.xls
//		XSSFWorkbook:是操作Excel2007的版本，扩展名是.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及以下");
excel=2;
}
if(POIXMLDocument.hasOOXMLHeader(inp)) {
System.out.println("2007及以上");
excel=3;
}

//		if (!path.endsWith(".xls")) {
//			excel =1;
//		}
//
