        items.add(item2);// 添加一个item

        channel.setItems(items);

        WireFeedOutput out = new WireFeedOutput();
        String str = "";
        try {
            str = out.outputString(channel);
        } catch (FeedException ex) {
            ex.printStackTrace();
        }
        return str;
    }

    public static void main(String[] args) {
        System.out.println(channleItemXml());
    }
}

@GetMapping(value = "feed", produces = "application/xml")
@ResponseBody
public String feed() {
    return RSSUtil.channleItemXml();
}

效果
