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);
