java.io.FileNotFoundException在提交多部分post请求时发生

我正在提交一个包含“文件”类型输入的多部分表单。 我正在使用此输入上载图像。表单提交给servlet，servlet随后将上传的文件信息传递给节点应用程序（使用API调用），节点应用程序存储文件

我的问题是，这不适用于我试图上传的大多数文件。在某些情况下，它确实有效，但我在这些文件中找不到任何独特之处

我得到的错误是：

[INFO] [talledLocalContainer] caused by: java.io.FileNotFoundException: < absolute-path-to-temp-dir>\temp\upload_1940e046_658b_40ae_9d6d_4a1ecac4e58d_00000083.tmp (The system cannot find the file specified)

当试图提交带有文件的表单时，我遇到了上述错误。在尝试调试代码时，我注意到在任何时间点目标目录中都没有具有给定名称的文件

我做错了什么

下面是堆栈跟踪-

问题可能在于您尝试上载的文件的大小

DiskFileItem dfi = (DiskFileItem) payload.get("file");

这意味着它将只能获取保存在磁盘上的文件（我相信只有10kb以上），因此您的问题可能是大小太小

试着改变

DiskFileItem dfi = (DiskFileItem) payload.get("file");

到

及

到

这将从磁盘和内存中获取文件数据，应该可以解决您的问题。

提供完整的堆栈跟踪。完成了，这有帮助吗？遗憾的是没有-但这实际上不是堆栈跟踪，只是一个合流日志。A表示代码中发生异常的位置。

DiskFileItem dfi = (DiskFileItem) payload.get("file");

FileItem dfi = (FileItem) payload.get("file");

builder.addBinaryBody("icon", dfi.getStoreLocation(), ContentType.create(dfi.getContentType()), dfi.getName());

builder.addBinaryBody("icon", dfi.get(), ContentType.create(dfi.getContentType()), dfi.getName());
