Springmvc+jquery.uploadify Uploading Files

Objective

Previously with ASP. Mvc+uploadify upload files, recently learned SPRINGMVC, so use springmvc+uploadify to do an upload file demo.

Just started to submit the form form, in the controller action with @requestparam multipartfile file will be able to get upload files information. After I directly use uploadify upload, interface did not make any adjustments, upload the process of reporting http400, the client's request does not meet the requirements of the interface, form Post submitted times the text parameter is in form data mode, Instead of uploadify, the parameter format is the way the request payload, so the interface is rewritten as a multipartservletrequest.

Development environment

SpringMVC4, Uploadify,

If you upload a file, you also need to download commons-fileupload, and also download Common-io, common-logging

Project structure

Normal form Upload

 <form action= /user/index  Span style= "color: #800000;" > " Method="  post   " Enctype="  multipart/form-data   ><input type="  file   name="  file   ><input type="  Span style= "color: #800000;" >submit   value="  upload  /></form> 

@RequestMapping ("Upload") public    @ResponseBody String  upload (@RequestParam multipartfile file) throws IOException {                 String path =request.getsession (). Getservletcontext (). Getrealpath ("Upload");        File File=new file (Path,file.getoriginalfilename ());            File.transferto (file); Save            The file return "/success";     }
