Openfire：通过Servlet群发消息

在Openfire中自带有Broadcase插件，可以让我们群发消息给全部用户或者组。不过如果是我们通过Servlet来实现这一功能，那么是能够增加一定的灵活性的。具体做法直接看Demo代码：

public class SafeServlet extends HttpServlet {    private JID serverAddress;    private MessageRouter router;    private UserManager userManager;    @Override    public void init() throws ServletException {        super.init();    }    @Override    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {        super.doGet(request, response);        // 获取服务器地址        serverAddress = new JID(XMPPServer.getInstance().getServerInfo().getXMPPDomain());        router = XMPPServer.getInstance().getMessageRouter();        userManager = UserManager.getInstance();        System.out.println("Require SafeServlet GET Method");        // 创建消息类        final Message message = new Message();        message.setFrom(serverAddress);        message.setSubject("Test subject");        message.setBody("Test body");        message.setType(Message.Type.chat);        // 获取所有用户        Collection<User> users = userManager.getUsers();        String xmppdomain = "@" + JiveGlobals.getProperty("xmpp.domain");        // 对所有用户进行遍历，发送消息        for (User u : users)        {            // 创建需要发送消息的备份，只将发送对象进行修改            final Message newMessage = message.createCopy();            newMessage.setTo(u.getUsername() + xmppdomain);            try {                TimerTask messageTask = new TimerTask() {                    @Override                    public void run() {                        router.route(newMessage);                    }                };                TaskEngine.getInstance().schedule(messageTask, 5000);            } catch (Exception e) {                Log.error(e.getMessage(), e);            }        }    }    @Override    public void destroy() {        super.destroy();                serverAddress = null;        router = null;        userManager = null;    }}
