使用apache POI - FileNotFound读取excel 2003文件

我正在编写一些代码来将Excel文件导入数据库 . 文件可能很大（数千行），所以我使用的是Event API . POI版本是3.9

我打开这样的文件：FileInputStream fin = new FileInputStream（file）;

//create record listener
HSSFRecordListener mainListener =  new HSSFRecordListener("aaa.xls");
// create a new org.apache.poi.poifs.filesystem.Filesystem
POIFSFileSystem poifs = new POIFSFileSystem(fin);
// get the Workbook (excel part) stream in a InputStream
din = poifs.createDocumentInputStream("Workbook");

有些文件正在调用最后一行来抛出FileNotFoundException . 实际上，如果我用7zip打开这些文件，则没有 Workbook 条目，但是有 Book .

如果找不到 Workbook ，我试图通过打开 Book 条目来解决这个问题 .

try {
    din = poifs.createDocumentInputStream("Workbook");
} catch (FileNotFoundException e) {
    try {
        din = poifs.createDocumentInputStream("Book");
    } catch (FileNotFoundException e1) {                    
        FileNotFoundException e2 = new FileNotFoundException("Neither Workbook nor Book found in file!");                    
        e2.initCause(e1);
        throw e2;
    }
}

这导致另一个例外：

谷歌有一些关于POI 3.2和3.7中的 fixed 错误的信息，它们与异常 Not enough data (0) to read requested (2) bytes 有关，但它似乎是其他的东西 .

可以在Excel 2007中成功打开相同的文件 . 当我使用 Save As=>Excel 97/2003 手动保存它们时，7zip显示 Book 条目已被 Workbook 替换，我可以使用Apache POI成功导入它们 .

有没有人发现这个问题？如何解决它？

EDIT

问题是当我尝试打开以Microsoft Excel 5.0 / 95文件格式保存的文件时 .

要重现此问题，请创建新电子表格，输入任何数据，然后另存为=> Microsoft Excel 5.0 / 95工作簿（* .xls） .

有没有办法用apache POI读取这种格式，还是我必须强制我的用户在上传之前升级他们的工作簿？
