Struts2 upload file error

I want to upload a file to my web project, but I'm getting:

WARN o.a.struts2.dispatcher.Dispatcher - Could not find create multipart save directory '/temp'. WARN o.a.s.d.m.JakartaMultiPartRequest - Unable to parse request org.apache.commons.fileupload.FileUploadBase$IOFileUploadException: Processing of multipart/form-data request failed. /temp/upload_1e39874d_effe_405b_9a92_3050ca60a661_00000000.tmp (No such file or directory)

so I want to change the upload directory

<struts>
    <constant name="struts.multipart.saveDir" value="/tmp"></constant>
    <package name="brand-struts" extends="abstract-struts">
<action name="saveBatchBrandGoodsInfo" class="brandgoodsAction" 
                                      method="saveBatchBrandGoodsInfo">
            <interceptor-ref name="fileUpload">             
                <param name="savePath">/upload</param>  
                <param name="maximumSize">1024000</param>  
            </interceptor-ref> 
            <result name="data" type="json">
                <param name="root">data</param>
            </result>
        </action>
    </package>

</struts>

but it doesn't work, I keep getting the same error

Solution

    1. AFAIK, there's no such thing as an abstract-struts package. Just extend struts-default and remove the savePath customization.

    2. You're including only the fileUpload Interceptor, not the whole defaultStack. You need to do:

      <interceptor-ref name="defaultStack">
    <param name="fileUpload.maximumSize">1024000</param>  
</interceptor-ref>

    Also ensure your form has enctype="multipart/form-data".
