继续上一章smack的讲述，聊天室的操作，聊天室也是openfire提供的一种形式，类似qq的讨论组，并非群，可以多人加入进来进行群聊。
1.创建聊天室
public boolean createChatRoom(String roomName, String subject) {
boolean result = false;
try {
MultiUserChat muc = new MultiUserChat(connectManager.getConnection(), roomName + "@conference." + connectManager.getDomain());
muc.create(connectManager.getNode());
Form form = muc.getConfigurationForm();
Form submitForm = form.createAnswerForm();
for (Iterator fields = form.getFields(); fields.hasNext();) {
FormField field = (FormField) fields.next();
if (!FormField.TYPE_HIDDEN.equals(field.getType()) && field.getVariable() != null) {
submitForm.setDefaultAnswer(field.getVariable());
}
}
// submitForm.setAnswer("muc#roomconfig_roomdesc", "wwh2222");
List list = new ArrayList();
list.add("20");
submitForm.setAnswer("muc#roomconfig_maxusers", list);
submitForm.setAnswer("muc#roomconfig_persistentroom", true);
submitForm.setAnswer("muc#roomconfig_membersonly", false);
submitForm.setAnswer("muc#roomconfig_allowinvites", true);
submitForm.setAnswer("muc#roomconfig_enablelogging", true);
submitForm.setAnswer("x-muc#roomconfig_reservednick", true);
submitForm.setAnswer("x-muc#roomconfig_canchangenick", false);
submitForm.setAnswer("x-muc#roomconfig_registration", false);
muc.sendConfigurationForm(submitForm);
muc.changeSubject(subject);
result = true;
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
创建聊天室，主要就是在创建的时候根据需求对聊天室的一些属性进行设置
房间名称 text-single muc#roomconfig_roomname
描述 text-single muc#roomconfig_roomdesc
允许占有者更改主题 boolean muc#roomconfig_changesubject
最大房间占有者人数 list-single muc#roomconfig_maxusers
其 Presence 是 Broadcast 的角色 list-multi muc#roomconfig_presencebroadcast
列出目录中的房间 boolean muc#roomconfig_publicroom
房间是持久的 boolean muc#roomconfig_persistentroom
房间是适度的 boolean muc#roomconfig_moderatedroom
房间仅对成员开放 boolean muc#roomconfig_membersonly
允许占有者邀请其他人 boolean muc#roomconfig_allowinvites
需要密码才能进入房间 boolean muc#roomconfig_passwordprotectedroom
密码 text-private muc#roomconfig_roomsecret
能够发现占有者真实 JID 的角色 list-single muc#roomconfig_whois
登录房间对话 boolean muc#roomconfig_enablelogging
仅允许注册的昵称登录 boolean x-muc#roomconfig_reservednick
允许使用者修改昵称 boolean x-muc#roomconfig_canchangenick
允许用户注册房间 boolean x-muc#roomconfig_registration
房间管理员 jid-multi muc#roomconfig_roomadmins
房间拥有者 jid-multi muc#roomconfig_roomowners

2.加入聊天室
public boolean joinChatRoom(String roomName) {
boolean result = false;
try {
MultiUserChat muc = new MultiUserChat(connectManager.getConnection(), roomName + "@conference." + connectManager.getDomain());
// 添加消息监听
muc.addMessageListener(new UcGroupChatManagerListener(this));
// 添加其他聊天室人员状态变化监听
muc.addParticipantStatusListener(new UcParticipantStatusListener(this, roomName));
// 添加直接在聊天室的状态变化监听
muc.addUserStatusListener(new UcUserStatusListener(this, roomName));
// 添加邀请被拒绝的监听
muc.addInvitationRejectionListener(new UcInvitationRejectionListener(this, roomName));
muc.addPresenceInterceptor(new UcPresenceInterceptor());
// 设置历史消息数量
DiscussionHistory history = new DiscussionHistory();
history.setMaxChars(0);
muc.join(connectManager.getNode(), null, history, SmackConfiguration.getPacketReplyTimeout());
// muc.grantOwnership("10110@kfas1/Spark 2.6.3");//对聊天室一些权限的授予，与删除
// muc.grantAdmin("10110@kfas1/Spark 2.6.3");
// muc.grantMembership("10110@kfas1/Spark 2.6.3");
// muc.grantModerator("10110");
// muc.grantVoice("10110");
// muc.revokeVoice("10110");
muc.revokeAdmin("10110@kfas1/Spark 2.6.3");
mucMap.put(roomName, muc);
result = true;
} catch (XMPPException e) {
log.error("加入聊天室异常", e);
}
return result;
}
消息包：
<presence id="CC26U-4" to="testroom@conference.wenwh-pc/10110">
<x xmlns="http://jabber.org/protocol/muc">
<history maxchars="0" />
</x>
</presence>
3.离开聊天室
public boolean departChatRoom(String roomName) {
boolean result = false;
MultiUserChat muc = mucMap.get(roomName);
if (muc != null) {
muc.leave();
mucMap.remove(roomName);
result = true;
}
return result;
}
消息包：
<presence id="fmmBY-5" to="testroom@conference.wenwh-pc/10110" type="unavailable"></presence>
4.邀请加入聊天室
public boolean inviteChatRoom(String roomName, String toJid, String reason) {
boolean result = false;
MultiUserChat muc = mucMap.get(roomName);
if (muc != null) {
muc.invite(toJid, reason);
result = true;
}
return result;
}
消息包：
<message id="34B0W-5" to="testroom@conference.wenwh-pc/10110">
<x xmlns="http://jabber.org/protocol/muc#user">
<invite to="10111@wenwh-pc">
<reason>一起聊天</reason>
</invite>
</x>
</message>
5.拒绝加入聊天室
public void rejectInvite(String room, String inviter, String reason) {
MultiUserChat.decline(connectManager.getConnection(), room, inviter, reason);
}
消息包：
<message from="testroom@conference.wenwh-pc" to="10110@wenwh-pc">
<x xmlns="http://jabber.org/protocol/muc#user">
<decline from="10111@wenwh-pc">
<reason>No thank you</reason>
</decline>
</x>
</message>
6.查询聊天室人员名字
public List<String> findMulitUser(String roomName) {
MultiUserChat muc = mucMap.get(roomName);
List<String> listUser = new ArrayList<String>();
if (muc != null) {
Iterator<String> it = muc.getOccupants();
while (it.hasNext()) {
String name = StringUtils.parseResource(it.next());
listUser.add(name);
}
}
return listUser;
}
7.发送聊天室消息
public boolean sendChatMessage(String roomName, String content) {
boolean result = false;
try {
MultiUserChat muc = mucMap.get(roomName);
if (muc != null) {
Message message = new Message();
message.setBody(content);
message.setTo(muc.getRoom());
message.setType(Message.Type.groupchat);
message.setSubject(MSG_SUBJECT);
muc.sendMessage(message);
result = true;
}
} catch (XMPPException e) {
log.error("发送消息异常", e);
}
return result;
}
消息包：
<message id="f6tkr-5" to="testroom@conference.wenwh-pc" type="groupchat">
<body>测试聊天室消息</body>
</message>
8.聊天室中角色与关系
实例在上面加入聊天室已经给出
角色：
moderator：主持人 （可以进行踢人，禁止发言等授权）
participant：参与者 （可以发言）
visitor：访客（不能发言）
none：无
关系：
owner：拥有者
admin：管理员
member：会员
outcast：被禁止加入的
none：无
在smcak里面的授权：（角色会随着关系变化，反之不会）
授予拥有者，管理员，会员，发言，主持人
被授予拥有，管理的时候，角色自动变成：主持人
被授予会员的时候，角色变成：参与者
被授予主持人，关系不会变化
被禁止发言：角色变成访客
聊天室的主要操作都在这里讲述，其实可能还有一些其他的，大家可以多看看smack的源码就会发现更多的隐藏协议。
