smack 4.1创建群聊

smack 4.1.1版本对群聊修改了很多,MultUserChat的构造函数修改成了私有,以前通过new MultUserChat创建聊天室,现在通过MultUserChatMananger先通过roomId初始化一个聊天室.

String roomId = "test003";
String name="test_group_chat";
String desc = "the test group chat";
String nick="test";

try {

    //获取房间管理对象
    MultiUserChatManager manager = MultiUserChatManager.getInstanceFor(XmppConnectionManager.getInstance().getConnection());
    //创建一个房间
    MultiUserChat muc = manager.getMultiUserChat(StringUtils.getGroupRootFullId(roomId));
    muc.create(nick);

    // User1 (which is the room owner) configures the room as a moderated room
    Form form = muc.getConfigurationForm();

    Form answerForm = form.createAnswerForm();
    //向提交的表单添加默认答复,获取房间的默认设置菜单
    for(FormField field : form.getFields() ){
       if(!FormField.Type.hidden.name().equals(field.getType()) && field.getVariable() != null) {
           answerForm.setDefaultAnswer(field.getVariable());
        }
   }

    //muc#
    //房间名称
    answerForm.setAnswer(FormField.FORM_TYPE, "http://jabber.org/protocol/muc#roomconfig");
    //设置房间名称
    answerForm.setAnswer("muc#roomconfig_roomname",name);
    //设置房间描述
    answerForm.setAnswer("muc#roomconfig_roomdesc", desc);
    //是否允许修改主题
    answerForm.setAnswer("muc#roomconfig_changesubject", true);

    //设置房间最大用户数
    List<String> maxusers = new ArrayList<String>();
    maxusers.add("50");
    answerForm.setAnswer("muc#roomconfig_maxusers", maxusers);


    List<String> cast_values = new ArrayList<String>();
    cast_values.add("moderator");
    cast_values.add("participant");
    cast_values.add("visitor");
    answerForm.setAnswer("muc#roomconfig_presencebroadcast", cast_values);
    //设置为公共房间
    answerForm.setAnswer("muc#roomconfig_publicroom", true);
    //设置为永久房间
    answerForm.setAnswer("muc#roomconfig_persistentroom", true);
    //允许修改昵称
    answerForm.setAnswer("x-muc#roomconfig_canchangenick", true);
    //允许用户登录注册房间
    answerForm.setAnswer("x-muc#roomconfig_registration", true);


    muc.sendConfigurationForm(answerForm);
    muc.join(nick);
