Java實現RSS

RSS是一個標準的XML檔案，Rss閱讀器可以讀取這個XML檔案獲得文章的資訊，使使用者可以通過Rss閱讀器而非瀏覽器閱讀Blog，我們只要動態產生這個XML檔案便可以了。RSSLibJ是一個專門讀取和產生RSS的小巧實用的Java庫，大小僅25k，可以從http://sourceforge.net/projects/rsslibj/下載rsslibj-1_0RC2.jar和它需要的EXMLjar兩個檔案，然後複製到web/WEB-INF/lib/下。  rsslibj-1_0RC2.jar：http://sourceforge.net/project/downloading.php?group_id=71153&use_mirror=nchc&filename=rsslibj-1_0RC2.jar&27763931  EXML.jar：http://rsslibj.cvs.sourceforge.net/rsslibj/rsslibj/lib/EXML.jar?view=log  下載下來之後把 擴張名.zip 改為 .jar 就行了。

import com.rsslibj.elements.Channel;public class Writer {    public static void main(String[] args)             throws InstantiationException, ClassNotFoundException,             IllegalAccessException {        Channel channel=new Channel();        channel.setDescription("This is my sample channel.");        channel.setLink("http://localhost/");        channel.setTitle("My Channel");        channel.setImage("http://localhost/",                 "The Channel Image",                 "http://localhost/foo.jpg");        channel.setTextInput("http://localhost/search",                 "Search The Channel Image",                 "The Channel Image",                 "s");        channel.addItem("http://localhost/item1",                "The First Item covers details on the first item>",                "The First Item")                .setDcContributor("Joseph B. Ottinger");        channel.addItem("http://localhost/item2",                "The Second Item covers details on the second item",                "The Second Item")                .setDcCreator("Jason Bell");        System.out.println("The feed in RDF: "+channel.getFeed("rss"));    }}

Channel channel = new Channel(); channel.setDescription(account.getDescription()); baseUrl = baseUrl.substring(0, n); channel.setLink("http://server-name/home.c?accountId=" + accountId); channel.setTitle(account.getTitle()); List articles = facade.getArticles(accountId, account.getMaxPerPage(), 1); Iterator it = articles.iterator(); while(it.hasNext()) {     Article article = (Article)it.next();     channel.addItem("http://server-name/article.c?articleId=" + article.getArticleId(),         article.getSummary(), article.getTitle()     ); } // 輸出xml: response.setContentType("text/xml"); PrintWriter pw = response.getWriter(); pw.print(channel.getFeed("rss")); pw.close();
