Springmvc File Upload

I tested the SPRINGMVC package to the good parser Multipartfile, which contains the information to upload the file

1. Forms

<!--Note: 1 must be a post to submit the value of the 2.enctype attribute must be Multipart/form-data -       <formAction= "/upload/upload"Method= "POST"enctype= "Multipart/form-data">           <inputtype= "File"name= "AA" />           <inputtype= "Submit"value= "Submit" />       </form>  </Body>

2. Writing Controller

1) upload to Local disk

/*** Upload to Local Disk *@paramAA receives NAME=AA, the form element that contains the information of the file *@return     */@RequestMapping ("/upload")     PublicString upload (multipartfile aa) {Try {            //File UploadAa.transferto (NewFile ("d:\\" +aa.getoriginalfilename ())); } Catch(Exception e) {e.printstacktrace (); }        return"Index"; }

2) upload to Tomcat

/*** Upload to the upload folder of the Web project, first create a upload folder in the project *@paramAA *@paramRequest *@return     */@RequestMapping ("/upload1")     PublicString upload1 (multipartfile aa,httpservletrequest request) {System.out.println (Aa.getoriginalfilename ()); Try {            //path to File uploadString Realpath = Request.getsession (). Getservletcontext (). Getrealpath ("/upload"); Aa.transferto (NewFile (Realpath,aa.getoriginalfilename ()));        } Catch(Exception e) {e.printstacktrace (); }        return"Back/ok"; }

3.SPRINGMVC configuration file

<!--file upload Bean ID must be called Multipartresolver, and cannot be changed Springmvc file upload by default, but can set the size of the file upload -    <BeanID= "Multipartresolver"class= "Org.springframework.web.multipart.commons.CommonsMultipartResolver">        < Propertyname= "Maxuploadsize"value= "20971520"/>    </Bean>
