After migration to struts 2.3.24, file upload still not supported for greater than 2gb

问题

Adding the following the to struts.xml in struts2.3.24:

<constant name="struts.multipart.parser"  value="jakarta-stream" />
<constant name="struts.multipart.maxSize" value="3147483648" />

For reference the upload works as follows in the jsp:

<s:form id="uploadData" action="abc_UploadAction?method=Upload" namespace="xyz"   validateFields="false" method="post"    enctype="multipart/form-data">

For action mapping we use the concept of DMI. The action configuration is as follows:

<action name="abc_*" class="ABCAction">
<result type="chain">invoke_${module}_{1}_${method}</result>
</action>

But file upload still not working for large files of greater than 2gb. But the above code works fine for lesser size uploads,

回答1:

Why are you declaring a bean, if the documentation is not telling you to do so ?

Just change

<bean type="org.apache.struts2.dispatcher.multipart.MultiPartRequest" name="jakartaStream"
     class="org.apache.struts2.dispatcher.multipart.JakartaStreamMultiPartRequest" 
     scope="default" />
<constant name="struts.multipart.parser"  value="jakartaStream" />

to the right configuration that should be (hyphenized, not capitalized):

<constant name="struts.multipart.parser"  value="jakarta-stream" />
