since 7.0. Libraries or applications can provide their own View class or perform rendering in web handlers directly.

Abstract superclass for RSS Feed views, using the ROME package.

NOTE: As of Spring 4.1, this is based on the com.rometools variant of ROME, version 1.5. Please upgrade your build dependency.

Application-specific view classes will extend this class. The view will be held in the subclass itself, not in a template. Main entry points are the AbstractFeedView.buildFeedMetadata(Map, T, HttpServletRequest) and buildFeedItems(Map, HttpServletRequest, HttpServletResponse).

Thanks to Jettro Coenradie and Sergio Bossa for the original feed view prototype!

Since:

3.0

Method Details

newFeed

protected com.rometools.rome.feed.rss.Channel newFeed()

Deprecated, for removal: This API element is subject to removal in a future version.

Create a new Channel instance to hold the entries.

By default returns an RSS 2.0 channel, but the subclass can specify any channel.

Specified by:

newFeed in class AbstractFeedView<com.rometools.rome.feed.rss.Channel>

Returns:

the newly created Feed instance

buildFeedEntries

protected final void buildFeedEntries(Map<String,Object> model,
 com.rometools.rome.feed.rss.Channel channel,
 jakarta.servlet.http.HttpServletRequest request,
 jakarta.servlet.http.HttpServletResponse response)
                               throws Exception

Deprecated, for removal: This API element is subject to removal in a future version.

Invokes buildFeedItems(Map, HttpServletRequest, HttpServletResponse) to get a list of feed items.

Specified by:

buildFeedEntries in class AbstractFeedView<com.rometools.rome.feed.rss.Channel>

Parameters:

model - the model Map

channel - the feed to add entries to

request - in case we need locale etc. Shouldn't look at attributes.

response - in case we need to set cookies. Shouldn't write to it.

Throws:

Exception - any exception that occurred during building

buildFeedItems

protected abstract List<com.rometools.rome.feed.rss.Item> buildFeedItems(Map<String,Object> model,
 jakarta.servlet.http.HttpServletRequest request,
 jakarta.servlet.http.HttpServletResponse response)
                                                                  throws Exception

Deprecated, for removal: This API element is subject to removal in a future version.

Subclasses must implement this method to build feed items, given the model.

Note that the passed-in HTTP response is just supposed to be used for setting cookies or other HTTP headers. The built feed itself will automatically get written to the response after this method returns.

Parameters:

model - the model Map

request - in case we need locale etc. Shouldn't look at attributes.

response - in case we need to set cookies. Shouldn't write to it.

Returns:

the feed items to be added to the feed

Throws:

Exception - any exception that occurred during document building
