Struts2上传文件错误

Question

我想将文件上传到我的网络项目，但我得到：

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)

所以我想更改上传目录

<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>

但它不起作用，我一直收到同样的错误

Answer 1

据我所知，没有 abstract-struts 包这样的东西。只需扩展 struts-default 并删除 savePath 自定义。

您只包含 fileUpload 拦截器，而不是整个 defaultStack。你需要做的：

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

还要确保您的表单具有 enctype="multipart/form-data".
