在上面的代码中，我使用FileInputStream导入文件，但此代码无效。我没有上传文件，我得到错误消息。在这个项目中我使用spring框架和hibernate
在上面的代码告诉我问题在哪里

我的控制器代码在

之下

public static Vector read(File fileName) {
    Vector rowStore = new Vector();
    try {
        FileInputStream inputFile = null;
        try {
            inputFile = new FileInputStream("D:/" + fileName);
        } catch (Exception e) {
            throw new RuntimeException(e.getMessage());
        }
        POIFSFileSystem systemFile = new POIFSFileSystem(inputFile);
        HSSFWorkbook wb = new HSSFWorkbook(systemFile);
        HSSFSheet sheet = wb.getSheetAt(0);
        Iterator rows = sheet.rowIterator();
        if (!"".equals(rows.toString())) {
            while (rows.hasNext()) {
                HSSFRow row = (HSSFRow) rows.next();
                Iterator cells = row.cellIterator();
                Vector cellStore = new Vector();
                while (cells.hasNext()) {
                    HSSFCell cell = (HSSFCell) cells.next();
                    cellStore.addElement(cell);
                }
                rowStore.addElement(cellStore);
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    return rowStore;
}

在您说自己在Windows操作系统上的标签中，您的错误在路径定义中。在Windows中，Path由＆＃34; \＆＃34;声明。而不是＆＃34; /＆＃34;。

在java中，\符号是转义符号，所以你必须转义才能使用它（sry for the many＆＃34; escape＆＃34;：D）：代码看起来像这样：

inputFile = new FileInputStream("D:\\" + fileName);

在java中上传Excel文件时出错
