RSS和Atom
Both AbstractAtomFeedView 和 AbstractRssFeedView 继承自
AbstractFeedView 基类，并分别用于提供 Atom 和 RSS Feed 视图。它们
基于 ROME 项目，并位于
包 org.springframework.web.servlet.view.feed 中。
AbstractAtomFeedView 要求您实现 buildFeedEntries() 方法，并且可选地重写 buildFeedMetadata() 方法（默认实现为空）。以下示例展示了如何实现：
-
Java
-
Kotlin
public class SampleContentAtomView extends AbstractAtomFeedView {
@Override
protected void buildFeedMetadata(Map<String, Object> model,
Feed feed, HttpServletRequest request) {
// implementation omitted
}
@Override
protected List<Entry> buildFeedEntries(Map<String, Object> model,
HttpServletRequest request, HttpServletResponse response) throws Exception {
// implementation omitted
}
}class SampleContentAtomView : AbstractAtomFeedView() {
override fun buildFeedMetadata(model: Map<String, Any>,
feed: Feed, request: HttpServletRequest) {
// implementation omitted
}
override fun buildFeedEntries(model: Map<String, Any>,
request: HttpServletRequest, response: HttpServletResponse): List<Entry> {
// implementation omitted
}
}类似的实现要求也适用于AbstractRssFeedView，如下例所示：
-
Java
-
Kotlin
public class SampleContentRssView extends AbstractRssFeedView {
@Override
protected void buildFeedMetadata(Map<String, Object> model,
Channel feed, HttpServletRequest request) {
// implementation omitted
}
@Override
protected List<Item> buildFeedItems(Map<String, Object> model,
HttpServletRequest request, HttpServletResponse response) throws Exception {
// implementation omitted
}
}class SampleContentRssView : AbstractRssFeedView() {
override fun buildFeedMetadata(model: Map<String, Any>,
feed: Channel, request: HttpServletRequest) {
// implementation omitted
}
override fun buildFeedItems(model: Map<String, Any>,
request: HttpServletRequest, response: HttpServletResponse): List<Item> {
// implementation omitted
}
}The buildFeedItems() 和 buildFeedEntries() 方法传递了HTTP请求，以防你需要访问Locale。HTTP响应仅在设置cookie或其他HTTP头时传递。方法返回后，feed将自动写入响应对象。
