spring mvc - Grails request.getFile always returning null -


i've been trying submit form contains multiple inputs (texts , 1 image) i'm unable retrieve image request (grails 3.0.4)

my create.gsp looks this:

<g:uploadform controller="advertisement" action="save">     <input name="name" type="text" id="advertisement_name" />     <input name="link" type="text" id="advertisement_url" />     <input id="add_banner_image" name="myimage" type="file" accept="image/png,image/jpeg" data-max-size="512000"/>     <g:submitbutton name="save" class="mdl-button mdl-js-button mdl-button--raised mdl-js-ripple-effect mdl-button--accent" value="salvar anúncio">    </g:submitbutton>  </g:uploadform>

my browser shows correct request payload:

------webkitformboundarysaaghui2q9vtfkky content-disposition: form-data; name="name"  filipe ------webkitformboundarysaaghui2q9vtfkky content-disposition: form-data; name="link"  https://www.filipescosta.com ------webkitformboundarysaaghui2q9vtfkky content-disposition: form-data; name="imagemlouca"; filename="exemplo.jpeg" content-type: image/jpeg   ------webkitformboundarysaaghui2q9vtfkky content-disposition: form-data; name="save"  salvar anúncio

my resources.groovy looks this:

beans = {     multipartresolver (org.springframework.web.multipart.commons.commonsmultipartresolver) {         maxuploadsize=2500000     } }

and application.yml looks this:

grails: mime:     disable:         accept:             header:                 useragents:                     - gecko                     - webkit                     - presto                     - trident     types:         all: '*/*'         atom: application/atom+xml         css: text/css         csv: text/csv         form: application/x-www-form-urlencoded         html:            - text/html           - application/xhtml+xml         js: text/javascript         json:           - application/json           - text/json         multipartform: multipart/form-data         pdf: application/pdf         rss: application/rss+xml         text: text/plain         hal:            - application/hal+json           - application/hal+xml         xml:           - text/xml           - application/xml urlmapping:     cache:         maxsize: 1000 controllers:     defaultscope: singleton converters:     encoding: utf-8 views:     default:         codec: html     gsp:         encoding: utf-8         htmlcodec: xml         codecs:             expression: html             scriptlets: html             taglib: none             staticparts: none

my controller looks this:

def save() {     println request.getfile('myimage')     println "request class: ${request.class}"     [...]      request.withformat {         form multipartform {             flash.message = message(code: 'default.created.message', args: [message(code: 'advertisement.label', default: 'advertisement'), advertisement.id])             redirect(uri:'/')         }         '*' { respond advertisement, [status: created, formats:['html']] }     } }

but in console, println message is:

null request class: class org.springframework.web.multipart.support.defaultmultiparthttpservletrequest

can take , me trick? i've been searching examples , couldn't find helps.

you define: attribute name="myimage" , try uppercase name -> request.getfile('myimage')
