java.lang.Object org.springframework.web.multipart.commons.CommonsFileUploadSupport org.springframework.web.portlet.multipart.CommonsPortletMultipartResolver
public class CommonsPortletMultipartResolver
PortletMultipartResolver implementation for Jakarta Commons FileUpload 1.1 or higher.
Provides maxUploadSize, maxInMemorySize, and defaultEncoding settings as bean properties (inherited from CommonsFileUploadSupport). See respective PortletFileUpload / DiskFileItemFactory properties (sizeMax, sizeThreshold, headerEncoding) for details in terms of defaults and accepted values.
Saves temporary files to the portlet container's temporary directory. Needs to be initialized either by an application context or via the constructor that takes a PortletContext (for standalone usage).

newFileUpload(FileItemFactory fileItemFactory)
Initialize the underlying org.apache.commons.fileupload.portlet.PortletFileUpload
instance. |
MultipartActionRequest |
resolveMultipart(ActionRequest request)
Parse the given portlet request into multipart files and parameters, and wrap the request inside a MultipartActionRequest object that provides access to file descriptors and makes contained parameters accessible via the standard PortletRequest methods. |
void |
setPortletContext(PortletContext portletContext)
Set the PortletContext that this object runs in. |
