File upload with Spring Web Flow

I have searched and read multiple answers on file upload using Spring Web Flow but all seems to give same result. Hence posting.

public class FileUploadForm {

    private transient MultipartFile file;



    //Additional fields

}

Flow

<view-state id="start" model="fileUploadForm">

    <transition on="submit" to="submit"/>

    <transition on="cancel" to="cancel"/>

</view-state>



<action-state id="submit">

    <evaluate expression="someActions.review(fileUploadForm)" />

    <transition on="success" to="home"/>

</action-state>

JSP

<form:form modelAttribute="fileUploadForm" enctype="multipart/form-data"> <input type="hidden" name="_flowExecutionKey" value="${flowExecutionKey}"/> <form:label path="file">Upload File</form:label> <form:input type="file" path="file"/> <button name="_eventId_upload">Upload Button</button> </form:form>

XML

<!--<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">-->

    <!--<property name="maxUploadSize" value="100000"/>-->

<!--</bean>-->



<bean id="filterMultipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

    <property name="maxUploadSize" value="100000" />

</bean>

JAVA

public String review(FileUploadForm fileUploadForm) {

    LOG.info("{}", fileUploadForm.getFile().getContentType());

    return "success";

}

At LOG.info getFile is null. I do get other fields filled in the form, but not the file field.

Can someone please point me in the right direction. Using Webflow 2.5.1

Try using a regular input file:

<input type="file" name="file" id="file"/>

[EDIT] to be complete, my working code also uses this form tag:

<form:form modelAttribute="fileUploadForm" action="${flowExecutionUrl}&${_csrf.parameterName}=${_csrf.token}" enctype="multipart/form-data">

and this type of submit button:

<input type="submit" id="upload" name="_eventId_upload" value="Upload"></span>
