public abstract class AbstractRssFeedView extends AbstractFeedView<com.rometools.rome.feed.rss.Channel>
Abstract superclass for RSS Feed views, using the ROME package.>NOTE: As of Spring 4.1, this is based on the
com.rometoolsvariant 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(java.util.Map<java.lang.String, java.lang.Object>, T, javax.servlet.http.HttpServletRequest)andbuildFeedItems(java.util.Map<java.lang.String, java.lang.Object>, javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse).Thanks to Jettro Coenradie and Sergio Bossa for the original feed view prototype!

方法详细资料
newFeed
protected com.rometools.rome.feed.rss.Channel newFeed()
Create a new Channel instance to hold the entries.By default returns an RSS 2.0 channel, but the subclass can specify any channel.
- 指定者:
newFeed在类中AbstractFeedView<com.rometools.rome.feed.rss.Channel>- 返回:
- the newly created Feed instance
buildFeedEntries
protected final void buildFeedEntries(Map<String,Object> model, com.rometools.rome.feed.rss.Channel channel, HttpServletRequest request, HttpServletResponse response) throws Exception
InvokesbuildFeedItems(Map, HttpServletRequest, HttpServletResponse)to get a list of feed items.- 指定者:
buildFeedEntries在类中AbstractFeedView<com.rometools.rome.feed.rss.Channel>- 参数:
model- the model Mapchannel- the feed to add entries torequest- in case we need locale etc. Shouldn't look at attributes.response- in case we need to set cookies. Shouldn't write to it.- 抛出:
Exception- any exception that occurred during building
buildFeedItems
protected abstract List<com.rometools.rome.feed.rss.Item> buildFeedItems(Map<String,Object> model, HttpServletRequest request, HttpServletResponse response) throws Exception
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.
- 参数:
model- the model Maprequest- in case we need locale etc. Shouldn't look at attributes.response- in case we need to set cookies. Shouldn't write to it.- 返回:
- the feed items to be added to the feed
- 抛出:
Exception- any exception that occurred during document building- 另请参阅:
