JSP上传内容类型为“application/octet-stream”的文件

Question

我正在开发一个项目，该项目使用内容类型“application/octet-stream”上载一些二进制数据，并且需要将其保存在BLOB列Oracle数据库。

我可以使用Commons fileupload吗？
这个任何示例代码？我只能找到内容类型为“multipart/form-data”的代码。

private byte[] getByteArrayFromUploadFile(HttpServletRequest request)throws Exception{ 
    ServletFileUpload upload = new ServletFileUpload(); 

    // Parse the request 
    FileItemIterator iter = null; 
    try{ 
     iter = upload.getItemIterator(request); 
    }catch (Exception e) { 
     System.out.println("Error occured during getting iterator"); 
    } 
    byte[] readBytes = null; 
    while (iter.hasNext()) { 
     FileItemStream item = null; 
     try{ 
      item = iter.next(); 
     }catch (Exception e) { 
      System.out.println("Error occured during Iteration");     
     } 

     String name = item.getFieldName(); 

     if (!item.isFormField()) { 
      BufferedInputStream stream = new BufferedInputStream(item.openStream()); 
      readBytes= new byte[stream.available()]; 
      System.out.println("total Number of Bytes:"+ readBytes.length);    
      stream.read(readBytes); 
     } 
    } 
    return readBytes; 
}
