Problem: Wie erzeuge ich einen RSS-Feed mit Rome und Spring MVC <\/strong><\/p>\n

L\u00f6sung:<\/strong><\/p>\n

Man l\u00e4dt sich Rome<\/a> und Spring Modules<\/a> herunter und packt beide Jars in seinen Classpath.<\/p>\n

Danach erzeugt man einen RSSView:<\/p>\n

\r\npublic class RSSView extends AbstractRssView\r\n{\r\n\tprivate static final String[] FEED_TYPE = {\"rss_0.90\",\"rss_0.91\",\"rss_0.92\",\"rss_0.93\",\"rss_0.94\",\"rss_1.0\",\"rss_2.0\",\"atom_0.3\"};\t\r\n\r\n\tprivate static final DateFormat DATE_PARSER = new SimpleDateFormat(\"yyyy-MM-dd\");\r\n\r\n\tprivate String description;\r\n\r\n\t\/**\r\n\t * Generates the Feed.\r\n\t *\/\r\n\t@SuppressWarnings(\"unchecked\")\r\n\t@Override\r\n\tprotected void buildFeed(Map model, HttpServletRequest request, HttpServletResponse response, SyndFeed feed)\r\n\t{\r\n\t\tfeed.setFeedType(FEED_TYPE[6]);\r\n\r\n\t\tfeed.setTitle(\"Peters Feeds\");\r\n\t\tfeed.setLink(getBaseUrl());\r\n\t\tfeed.setDescription(description);\r\n\r\n\t\tSyndImage image \t= new SyndImageImpl();\r\n\t\timage.setLink(getBaseUrl());\r\n\t\timage.setUrl(\"URLTOIMAGE\");\r\n\t\timage.setDescription(description);\r\n\t\timage.setTitle(\"Peter\");\r\n\t\tfeed.setImage(image);\r\n\r\n\t\tList entries = new ArrayList();\r\n\t\tSyndEntry entry;\r\n\r\n\t\tentry = new SyndEntryImpl();\r\n\t\tentry.setTitle(\"Rome v1.0\");\r\n\t\tentry.setLink(\"http:\/\/wiki.java.net\/bin\/view\/Javawsxml\/Rome01\");\r\n\t\tentry.setPublishedDate(DATE_PARSER.parse(\"2004-06-08\"));\r\n\t\tdescription = new SyndContentImpl();\r\n\t\tdescription.setType(\"text\/plain\");\r\n\t\tdescription.setValue(\"Initial release of Rome\");\r\n\t\tentry.setDescription(description);\r\n\t\tentries.add(entry);\r\n\r\n\t\tentry = new SyndEntryImpl();\r\n\t\tentry.setTitle(\"Rome v2.0\");\r\n\t\tentry.setLink(\"http:\/\/wiki.java.net\/bin\/view\/Javawsxml\/Rome02\");\r\n\t\tentry.setPublishedDate(DATE_PARSER.parse(\"2004-06-16\"));\r\n\t\tdescription = new SyndContentImpl();\r\n\t\tdescription.setType(\"text\/plain\");\r\n\t\tdescription.setValue(\"Bug fixes, minor API changes and some new features\");\r\n\t\tentry.setDescription(description);\r\n\t\tentries.add(entry);\r\n\r\n\t\tfeed.setEntries(entries);\r\n\r\n\t}\r\n\r\n\tpublic void setDescription(String description)\r\n\t{\r\n\t\tthis.description = description;\r\n\t}\r\n\r\n}\r\n\r\n<\/pre>\n
Anschlie\u00dfend erzeugt man den dazugeh\u00f6rigen Controller:<\/p>\n
\r\npublic class RssFeedController implements Controller\r\n{\r\n\r\n\t@Override\r\n\tpublic ModelAndView handleRequest(HttpServletRequest arg0,\r\n\t\t\tHttpServletResponse arg1) throws Exception\r\n\t{\r\n\r\n\t\treturn  new ModelAndView(\"rSSView\");\r\n\t}\r\n}\r\n\r\n<\/pre>\n
Als Letztes verdrahtet man alles in seiner dispatcher.xml:<\/p>\n
\r\n...\r\nRssFeedController<\/prop>\r\n\r\n\t\r\n\r\n\t<\/property>\r\n\r\n\t\r\n\t<\/bean>\r\n...\r\n<\/bean>\r\n<\/pre>\n
