I've attempted to follow the examples given here: How to send FormData objects with Ajax-requests in jQuery? However when I submit the data it gets rejected with the following stacktrace: Caused by: org.apache.commons.fileupload.FileUploadException: the request was rejected because no multipart boundary was found.

Spring MVC file upload controller - I'd like the controller to be called as soon as the upload starts

阅读更多关于 Spring MVC file upload controller - I'd like the controller to be called as soon as the upload starts

问题 Using a naked servlet's doPost, when a file upload starts, doPost is immediately called. I can then stream the files from the request object using the commons FileItemIterator. Using Spring MVC, I can't seem to get the controller method to fire until after the file(s) have all been received by the server, which is not ideal. I want my servlet/controller method to process as many files as it can and perform some rollback operations if an upload is interrupted. I can't do that with Spring MVC

This just won't work. The problem is that I do not know enough to even know what is supposed to happen. I can't debug this code. I'd like to store upload to temporary folder "temp" and then to move them to "applets". Please help? The servlet is obviously being accessed, but I can't find the uploaded files... Thanks in advance. Form (which is created using a scriptlet - I put this here if that could cause problems): <% out.write("<p>Upload a new game:</p>"); out.write("<form name=\"uploadForm\" action=\"game.jsp\" " + "method=\"POST\" enctype=\"multipart/form-data\">" + "<input type=\"file\"

I'm developing a spring mvc app with framework 3.2.3.RELEASE In my app I handle Multipart with StandardServletMultipartResolver, but with apache commons-fileupload 1.3 the things are the same.

Looking at org.springframework.web.multipart.support.Standard ServletMultipartResolver: public boolean isMultipart(HttpServletRequest request) { // Same check as in Commons FileUpload... if (!"post".equals
