我正在尝试使用 Apache Commons Streaming API 从 Excel 电子表格中获取信息。我不断收到以下错误:

    }


    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {

        doPost(request, response);

    }


    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        processRequest(request, response);
    }


}

这就是我的表单的外观:

<form action="ReportServlet" method="post" enctype="multipart/form-data">
                    <input type="file" name="file"/> 
                    <br />
                    <input type="submit" value="Upload Report" name="upload_report_btn" />
                </form>

我正在使用玻璃鱼。有什么想法为什么我不断收到此消息吗？

最佳答案

在您的循环中，您似乎假设到达的第一个也是唯一的多部分对象将是电子表格文件。表格本身也会出现。线索就是消息

Unable to read entire header; 13 bytes read; expected 512 bytes

请注意，表单的上传值为Upload Report，长度恰好为13 个字节。

如果您使用基于浏览器的调试工具(例如 Firebug 或 Fiddler)，您可以很容易地看到这一点。您的工具集中应该包含这些工具之一。

关于java - FileUpload (Apache Commons) 和 Java POI IOException : Unable to read entire header，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/11074683/
