Java实现RSS
RSS是一个标准的XML文件,Rss阅读器可以读取这个XML文件获得文章的信息,使用户可以通过Rss阅读器
而非浏览器阅读Blog,我们只要动态生成这个XML文件便可以了。RSSLibJ是一个专门读取和生成RSS的小
巧实用的Java库,大小仅25k,可以从http://sourceforge.net/projects/rsslibj/下载rsslibj-
1_0RC2.jar和它需要的EXMLjar两个文件,然后复制到web/WEB-INF/lib/下。
rsslibj-1_0RC2.jar下载地址:http://sourceforge.net/project/downloading.php?group_id=71153&use_mirror=nchc&filename=rsslibj-1_0RC2.jar&27763931
下载下来之后把 扩张名.zip 改为 .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() ); } // 输出xml: response.setContentType("text/xml"); PrintWriter pw = response.getWriter(); pw.print(channel.getFeed("rss")); pw.close();
