java - ServletFileUpload 异常

Question

情况:我正在上传一个包含几千条记录的文件。最大文件大小为 100 kB，没有问题。但是，当文件大小超过 100 kB 时出现异常。

问题:我在以下行遇到异常:

List<DiskFileItem> items = upload.parseRequest(request);

我得到的异常是:

Error while processing multipart request:org.apache.commons.fileupload.FileUploadBase$IOFileUploadException: Processing of multipart/form-data request failed. D:\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\DNDUtility\upload_tmp\upload_172408d6_14c27eae211__8000_00000001.tmp (The system cannot find the path specified) : Processing of multipart/form-data request failed. D:\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\DNDUtility\upload_tmp\upload_172408d6_14c27eae211__8000_00000001.tmp (The system cannot find the path specified)

我什至将 ServletUpload.MaxFileSize() 设置为 1 MB。但是，如果我尝试上传超过 100 kB 的文件，则会出现异常。

Answer 1

试试这个(将其设置为 3MB):

ServletFileUpload upload = new ServletFileUpload(new DiskFileItemFactory(3000 * 1024, tmpDir));
