smack+openfire 群聊（三）（解决创建群失败的问题，以及永久房间问题）

上一篇文章，我们已经写了，单聊和注册用户，我们这节讲一下创建群聊的问题以及发送群消息

第一步，创建房间，以及房间成员加入

public String createChatRoom(String nickName, String source, String kf) throws SmackException, IOException {
	HashMap<String, Object> map = new HashMap<>();
	map.put("customer_id", nickName);
	List<ChatGroup> list = chatGroupService.selectByMap(map);
	// 组装群聊jid,这里需要注意一下,群jid的格式就是 群名称@conference.openfire服务器名称
	String roomName = System.currentTimeMillis() + "";
	if (list.size() > 0) {
		return roomName;
	}

	// 管理员在每一个群里
	AbstractXMPPConnection connection = getXmpptcpConnection("admin", "admin");
	try {
		connection.connect();
		connection.login();
		ConnectionMap.put("admin", connection);
		String jid = roomName + "@conference." + connection.getServiceName();
		EntityBareJid groupJid = JidCreate.entityBareFrom(jid);

		MultiUserChatManager manager = MultiUserChatManager.getInstanceFor(connection);
		MultiUserChat muc = manager.getMultiUserChat(groupJid);
		muc.create(Resourcepart.from("admin"));
		// 获得聊天室的配置表单
		Form subform = muc.getConfigurationForm();
		// 根据原始表单创建一个要提交的新表单。
		Form form = subform.createAnswerForm();
		// 设置聊天室的新拥有者
		List<String> owners = new ArrayList<>();
		owners.add("admin" + "@" + openfireServer);//admin加入群成员
		owners.add(nickName + "@" + openfireServer);//客户加入群成员

		// 指派客服逻辑-----------------------------------------------------
		EntityBareJid userJid = JidCreate.entityBareFrom(kf + "@" + openfireServer);//客服加入群成员
		owners.add(userJid + "");
	

		form.setAnswer("muc#roomconfig_passwordprotectedroom", false);
		form.setAnswer("muc#roomconfig_roomname", roomName);
		form.setAnswer("muc#roomconfig_persistentroom", true);
		form.setAnswer("muc#roomconfig_changesubject", true);
		form.setAnswer("muc#roomconfig_publicroom", true);
		form.setAnswer("muc#roomconfig_allowinvites", true);
		form.setAnswer("muc#roomconfig_membersonly", false);
		form.setAnswer("muc#roomconfig_moderatedroom", false);
		form.setAnswer("muc#roomconfig_roomowners", owners);

                muc.sendConfigurationForm(form);
		muc.join(Resourcepart.from("admin"));


	} catch (Exception e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}

	return roomName;

}

第二步，就是发送群消息了

@RequestMapping("/sendRoomMsg")
	public void sendChatGroupMessage(String roomid, String username, String msg) throws Exception {
		AbstractXMPPConnection connection = ConnectionMap.get("admin");	
			connection = getXmpptcpConnection("admin", "admin");	
			// 拼凑jid
			connection.connect();
			if (!connection.isAuthenticated()) {
				connection.login();
				ConnectionMap.put("admin", connection);
			}
		}
		EntityBareJid jid = JidCreate.entityBareFrom(roomid + "@conference." + connection.getServiceName());
		// 创建一个MultiUserChat
		MultiUserChat muc = MultiUserChatManager.getInstanceFor(connection).getMultiUserChat(jid);
		MucEnterConfiguration.Builder builder = muc.getEnterConfigurationBuilder(Resourcepart.from("admin"));
		// 只获取最后99条历史记录
		builder.requestNoHistory();
		builder.requestMaxCharsHistory(0);

		MucEnterConfiguration mucEnterConfiguration = builder.build();
//		// 加入群
		muc.join(mucEnterConfiguration);
		muc.sendMessage(msg);

//		connection.disconnect();

	}
注意，上面的admin是我已经在openfire里创建好的用户
