java使用rome.jar实现rss阅读功能
rome是一个很好用的解析rss的工具包，支持rote格式，最近在项目中使用了此包，共享给大家。在此只公开部分代码public class FeedReader {
public static void main(String[] args) {String source = "http://www.36kr.com/feed";// source = "http://news.163.com/special/00011K6L/rss_newstop.xml";// source = "http://hi.baidu.com/ybhanxiao/rss";// source = "http://ybhanxiao.iteye.com/rss";// source="http://www.luoyundeng.com/?feed=rss2";// source = "http://yanglanvip.blog.sohu.com/rss";// source="http://feed.williamlong.info/";try {SyndFeed feed = readFeed(source);ReaderSource readerSource = new ReaderSource();if (feed != null) {getArticles(feed, readerSource, null);}System.out.println(readerSource.getSourceName() + readerSource.getSourceDesc());} catch (IllegalArgumentException e) {e.printStackTrace();} catch (FeedException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();} catch (SecurityException e) {System.out.print("异常" + e);}}/** * 请求rss并返回syndFeed * * @param source * @return * @throws IllegalArgumentException * @throws FeedException * @throws IOException * @author echo * @date 2012-1-11 */@SuppressWarnings("unchecked")public static SyndFeed readFeed(String source) throws IllegalArgumentException, FeedException, IOException {// SyndFeedInput:从远程读到xml结构的内容转成SyndFeedImpl实例SyndFeedInput input = new SyndFeedInput();// Locale.setDefault(Locale.ENGLISH);SyndFeed feed = null;if (source.startsWith("http")) {URLConnection feedUrl = new URL(source).openConnection();/** *解决此异常： java.io.IOException: Server returned HTTP response code: * 403 for URL 但是自己却可以用浏览器访问，发现可能是服务器对java程序屏蔽了。 * 因为服务器的安全设置不接受Java程序作为客户端访问，解决方案是设置客户端的User Agent */feedUrl.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 5.0; Windows NT; DigExt)");feedUrl.setConnectTimeout(5000);feed = input.build(new XmlReader(feedUrl));} else {File feedUrl = new File(source);feed = input.build(new XmlReader(feedUrl));}return feed;}}如果解析某些站点时候日期出现为空时可以再src下加入rome.properties文件，并将datetime.extra.masks的指改为如下：
yyyy-MM-dd HH:mm:ss|yyyy-MM-dd HH:mm|yyyy-MM-dd?
