How to write an RSS feed with Java?

问题:

I\'m using Java, and need to generate a simple, standards-compliant RSS feed. How can I go about this?

回答1:

I recommend using Rome:

// Feed header
SyndFeed feed = new SyndFeedImpl();
feed.setFeedType(\"rss_2.0\");
feed.setTitle(\"Sample Feed\");
feed.setLink(\"http://example.com/\");

// Feed entries
List entries = new ArrayList();
feed.setEntries(entries);

SyndEntry entry = new SyndEntryImpl();
entry.setTitle(\"Entry #1\");
entry.setLink(\"http://example.com/post/1\");
SyndContent description = new SyndContentImpl();
description.setType(\"text/plain\");
description.setValue(\"There is text in here.\");
entry.setDescription(description);
entries.add(entry);

// Write the feed to XML
StringWriter writer = new StringWriter();
new SyndFeedOutput().output(feed, writer);
System.out.println(writer.toString());
