@Override  public IQ handleIQ(IQ packet) throws UnauthorizedException { System.out.println(packet.toXML());//iqpackage：(因为麻烦所以，当前只提供单个用户对某房间的某权限添加)。iq包格式如下//<iq ><query>//<roomJID></><jID></><affiliation></>//</iq><query>IQ reply = IQ.createResultIQ(packet);reply.setChildElement(packet.getChildElement().createCopy());try {ClientSession session = sessionManager.getSession(packet.getFrom());if (session == null) {Log.error("Error during userInfo.

//下面都是对内部发送IQ请求来功能if ("owner".equals(affiliation.getText())|| "admin".equals(affiliation.getText())) {Element frag = muciq.setChildElement("query","http://jabber.org/protocol/muc#owner");Element item = frag.addElement("item");item.addAttribute("affiliation", affiliation.getText());item.addAttribute("jid", jID.getText());// Send the IQ packet that will modify the room's// configurationroom.getIQOwnerHandler().handleIQ(muciq, room.getRole());} else if ("member".equals(affiliation.getText())|| "outcast".equals(affiliation.getText())) {Element frag = muciq.setChildElement("query","http://jabber.org/protocol/muc#admin");Element item = frag.addElement("item");item.addAttribute("affiliation", affiliation.getText());item.addAttribute("jid", jID.getText());// Send the IQ packet that will modify the room's// configurationroom.getIQAdminHandler().handleIQ(muciq, room.getRole());}}} catch (Exception e) {reply.setError(PacketError.Condition.internal_server_error);return reply;}return reply;  } 

这样就完成了处理，记得把它加到你的插件中啊~

server.getIQRouter().addHandler(new RoomMemberIQHander());
