关于Smack编程库,前面我们提到,它是面向Java端的api,主要在PC上使用,利用它我们可以向openfire服务器注册用户,发送消息,并且可以通过监听器获得此用户的应答消息,以及构建聊天室,分组,个人通讯录等等。
下面我们写几个程序小例子测试一下。
(1)登录操作
- PPConnection.DEBUG_ENABLED=true;
- AccountManageraccountManager;
- finalConnectionConfigurationconnectionConfig=newConnectionConfiguration(
- "192.168.1.78",Integer.parseInt("5222"),"csdn.shimiso.com");
- //允许自动连接
- connectionConfig.setReconnectionAllowed(true);
- connectionConfig.setSendPresence(true);
- Connectionconnection=newXMPPConnection(connectionConfig);
- try{
- connection.connect();//开启连接
- accountManager=connection.getAccountManager();//获取账户管理类
- }catch(XMPPExceptione){
- thrownewIllegalStateException(e);
- }
- //登录
- connection.login("admin","admin","SmackTest");
- System.out.println(connection.getUser());
- connection.getChatManager().createChat("shimiso@csdn.shimiso.com",null).sendMessage("Helloword!");
PPConnection.DEBUG_ENABLED = true; AccountManager accountManager; final ConnectionConfiguration connectionConfig = new ConnectionConfiguration( "192.168.1.78", Integer.parseInt("5222"), "csdn.shimiso.com"); // 允许自动连接 connectionConfig.setReconnectionAllowed(true); connectionConfig.setSendPresence(true); Connection connection = new XMPPConnection(connectionConfig); try { connection.connect();// 开启连接 accountManager = connection.getAccountManager();// 获取账户管理类 } catch (XMPPException e) { throw new IllegalStateException(e); } // 登录 connection.login("admin", "admin","SmackTest"); System.out.println(connection.getUser()); connection.getChatManager().createChat("shimiso@csdn.shimiso.com",null).sendMessage("Hello word!");
运行结果:
在login中一共有三个参数,登录名,密码,资源名,可能有人不明白资源名到底是什么意思,其实就是客户端的来源,客户端的名称,如果不写它默认就叫smack,如果你用相同的账户不同的资源名和同一个人发三条消息,那将会弹出三个窗口,而不是一个窗口。
同时smack还为我们提供了非常好的调试工具Smack Debug,利用该工具我们可以准确的捕获详细的往返报文信息。
(2)下面我们继续写个聊天的例子:
- PPConnection.DEBUG_ENABLED=true;
- AccountManageraccountManager;
- finalConnectionConfigurationconnectionConfig=newConnectionConfiguration(
- "192.168.1.78",Integer.parseInt("5222"),"csdn.shimiso.com");
- //允许自动连接
- connectionConfig.setReconnectionAllowed(true);
- connectionConfig.setSendPresence(true);
- Connectionconnection=newXMPPConnection(connectionConfig);
- try{
- connection.connect();//开启连接
- accountManager=connection.getAccountManager();//获取账户管理类
- }catch(XMPPExceptione){
- thrownewIllegalStateException(e);
- }
- //登录
- connection.login("admin","admin","SmackTest3");
- ChatManagerchatmanager=connection.getChatManager();
- ChatnewChat=chatmanager.createChat("shimiso@csdn.shimiso.com",newMessageListener(){
- publicvoidprocessMessage(Chatchat,Messagemessage){
- if(message.getBody()!=null){
- System.out.println("Receivedfrom【"
- +message.getFrom()+"】message:"
- +message.getBody());
- }
- }
- });
- Scannerinput=newScanner(System.in);
- while(true){
- Stringmessage=input.nextLine();
- newChat.sendMessage(message);
- }
PPConnection.DEBUG_ENABLED = true; AccountManager accountManager; final ConnectionConfiguration connectionConfig = new ConnectionConfiguration( "192.168.1.78", Integer.parseInt("5222"), "csdn.shimiso.com"); // 允许自动连接 connectionConfig.setReconnectionAllowed(true); connectionConfig.setSendPresence(true); Connection connection = new XMPPConnection(connectionConfig); try { connection.connect();// 开启连接 accountManager = connection.getAccountManager();// 获取账户管理类 } catch (XMPPException e) { throw new IllegalStateException(e); } // 登录 connection.login("admin", "admin","SmackTest3"); ChatManager chatmanager = connection.getChatManager(); Chat newChat = chatmanager.createChat("shimiso@csdn.shimiso.com", new MessageListener() { public void processMessage(Chat chat, Message message) { if (message.getBody() != null) { System.out.println("Received from 【" + message.getFrom() + "】 message: " + message.getBody()); } } }); Scanner input = new Scanner(System.in); while (true) { String message = input.nextLine(); newChat.sendMessage(message); }
运行结果:
这里我们用Scanner来捕捉用户在控制台的键盘操作,将信息发出,同时创建了一个MessageListener监听,在其中强制实现processMessage方法即可捕获发回的信息,在初次使用上还是较为容易上手的,我们只要细心查看API即可逐步深入下去。
(3)除了聊天以外我们经常还能想到就是广播
需要给所有在线的用户发送一个通知,或者给所有在线和离线的用户全发送,我们先演示如何给在线用户发送一个广播:
- PPConnection.DEBUG_ENABLED=false;
- AccountManageraccountManager;
- finalConnectionConfigurationconnectionConfig=newConnectionConfiguration(
- "192.168.1.78",Integer.parseInt("5222"),"csdn.shimiso.com");
- //允许自动连接
- connectionConfig.setReconnectionAllowed(true);
- connectionConfig.setSendPresence(true);
- Connectionconnection=newXMPPConnection(connectionConfig);
- try{
- connection.connect();//开启连接
- accountManager=connection.getAccountManager();//获取账户管理类
- }catch(XMPPExceptione){
- thrownewIllegalStateException(e);
- }
- connection.login("admin","admin","SmackTest3");
- Messagenewmsg=newMessage();
- newmsg.setTo("shimiso@csdn.shimiso.com");
- newmsg.setSubject("重要通知");
- newmsg.setBody("今天下午2点60分有会!");
- newmsg.setType(Message.Type.headline);//normal支持离线
- connection.sendPacket(newmsg);
- connection.disconnect();
PPConnection.DEBUG_ENABLED = false; AccountManager accountManager; final ConnectionConfiguration connectionConfig = new ConnectionConfiguration( "192.168.1.78", Integer.parseInt("5222"), "csdn.shimiso.com"); // 允许自动连接 connectionConfig.setReconnectionAllowed(true); connectionConfig.setSendPresence(true); Connection connection = new XMPPConnection(connectionConfig); try { connection.connect();// 开启连接 accountManager = connection.getAccountManager();// 获取账户管理类 } catch (XMPPException e) { throw new IllegalStateException(e); } connection.login("admin", "admin","SmackTest3"); Message newmsg = new Message(); newmsg.setTo("shimiso@csdn.shimiso.com"); newmsg.setSubject("重要通知"); newmsg.setBody("今天下午2点60分有会!"); newmsg.setType(Message.Type.headline);// normal支持离线 connection.sendPacket(newmsg); connection.disconnect();
运行结果:
将参数设置为Message.Type.normal即可支持离线广播,openfire系统会自动判断该用户是否在线,如果在线就直接发送出去,如果不在线则将信息存入ofoffline表,现在我将shimiso用户退出登录,再给它发消息,我们可以进入openfire库的ofoffline表中,非常清楚看到里面躺着一条离线消息记录是发给shimiso这个用户的
(4)那么我们如何让shimiso这个用户一登陆就取到离线消息呢?
请看如下代码
- PPConnection.DEBUG_ENABLED=false;
- AccountManageraccountManager;
- finalConnectionConfigurationconnectionConfig=newConnectionConfiguration(
- "192.168.1.78",Integer.parseInt("5222"),"csdn.shimiso.com");
- //允许自动连接
- connectionConfig.setReconnectionAllowed(true);
- connectionConfig.setSendPresence(false);//不要告诉服务器自己的状态
- Connectionconnection=newXMPPConnection(connectionConfig);
- try{
- connection.connect();//开启连接
- accountManager=connection.getAccountManager();//获取账户管理类
- }catch(XMPPExceptione){
- thrownewIllegalStateException(e);
- }
- connection.login("shimiso","123","SmackTest");
- OfflineMessageManagerofflineManager=newOfflineMessageManager(
- connection);
- try{
- Iterator<org.jivesoftware.smack.packet.Message>it=offlineManager
- .getMessages();
- System.out.println(offlineManager.supportsFlexibleRetrieval());
- System.out.println("离线消息数量:"+offlineManager.getMessageCount());
- Map<String,ArrayList<Message>>offlineMsgs=newHashMap<String,ArrayList<Message>>();
- while(it.hasNext()){
- org.jivesoftware.smack.packet.Messagemessage=it.next();
- System.out
- .println("收到离线消息,Receivedfrom【"+message.getFrom()
- +"】message:"+message.getBody());
- StringfromUser=message.getFrom().split("/")[0];
- if(offlineMsgs.containsKey(fromUser)){
- offlineMsgs.get(fromUser).add(message);
- }else{
- ArrayList<Message>temp=newArrayList<Message>();
- temp.add(message);
- offlineMsgs.put(fromUser,temp);
- }
- }
- //在这里进行处理离线消息集合......
- Set<String>keys=offlineMsgs.keySet();
- Iterator<String>offIt=keys.iterator();
- while(offIt.hasNext()){
- Stringkey=offIt.next();
- ArrayList<Message>ms=offlineMsgs.get(key);
- for(inti=0;i<ms.size();i++){
- System.out.println("-->"+ms.get(i));
- }
- }
- offlineManager.deleteMessages();
- }catch(Exceptione){
- e.printStackTrace();
- }
- offlineManager.deleteMessages();//删除所有离线消息
- Presencepresence=newPresence(Presence.Type.available);
- nnection.sendPacket(presence);//上线了
- nnection.disconnect();//关闭连接
PPConnection.DEBUG_ENABLED = false; AccountManager accountManager; final ConnectionConfiguration connectionConfig = new ConnectionConfiguration( "192.168.1.78", Integer.parseInt("5222"), "csdn.shimiso.com"); // 允许自动连接 connectionConfig.setReconnectionAllowed(true); connectionConfig.setSendPresence(false);//不要告诉服务器自己的状态 Connection connection = new XMPPConnection(connectionConfig); try { connection.connect();// 开启连接 accountManager = connection.getAccountManager();// 获取账户管理类 } catch (XMPPException e) { throw new IllegalStateException(e); } connection.login("shimiso", "123","SmackTest"); OfflineMessageManager offlineManager = new OfflineMessageManager( connection); try { Iterator<org.jivesoftware.smack.packet.Message> it = offlineManager .getMessages(); System.out.println(offlineManager.supportsFlexibleRetrieval()); System.out.println("离线消息数量: " + offlineManager.getMessageCount()); Map<String, ArrayList<Message>> offlineMsgs = new HashMap<String, ArrayList<Message>>(); while (it.hasNext()) { org.jivesoftware.smack.packet.Message message = it.next(); System.out .println("收到离线消息, Received from 【" + message.getFrom() + "】 message: " + message.getBody()); String fromUser = message.getFrom().split("/")[0]; if (offlineMsgs.containsKey(fromUser)) { offlineMsgs.get(fromUser).add(message); } else { ArrayList<Message> temp = new ArrayList<Message>(); temp.add(message); offlineMsgs.put(fromUser, temp); } } // 在这里进行处理离线消息集合...... Set<String> keys = offlineMsgs.keySet(); Iterator<String> offIt = keys.iterator(); while (offIt.hasNext()) { String key = offIt.next(); ArrayList<Message> ms = offlineMsgs.get(key); for (int i = 0; i < ms.size(); i++) { System.out.println("-->" + ms.get(i)); } } offlineManager.deleteMessages(); } catch (Exception e) { e.printStackTrace(); } offlineManager.deleteMessages();//删除所有离线消息 Presence presence = new Presence(Presence.Type.available); nnection.sendPacket(presence);//上线了 nnection.disconnect();//关闭连接
运行结果:
这里我们需要特别当心的是先不要告诉openfire服务器你上线了,否则永远也拿不到离线消息,用下面英文大概意思就是在你上线之前去获取离线消息,这么设计是很有道理的。
The OfflineMessageManager helps manage offline messages even before the user has sent an available presence. When a user asks for his offline messages before sending an available presence then the server will not send a flood with all the offline messages when the user becomes online. The server will not send a flood with all the offline messages to the session that made the offline messages request or to any other session used by the user that becomes online.
拿到离线消息处理完毕之后删除离线消息offlineManager.deleteMessages() 接着通知服务器上线了。
(5)下面我们来看看如何来发送文件
- PPConnection.DEBUG_ENABLED=false;
- AccountManageraccountManager;
- finalConnectionConfigurationconnectionConfig=newConnectionConfiguration(
- "192.168.1.78",Integer.parseInt("5222"),"csdn.shimiso.com");
- //允许自动连接
- connectionConfig.setReconnectionAllowed(true);
- connectionConfig.setSendPresence(true);
- Connectionconnection=newXMPPConnection(connectionConfig);
- try{
- connection.connect();//开启连接
- accountManager=connection.getAccountManager();//获取账户管理类
- }catch(XMPPExceptione){
- thrownewIllegalStateException(e);
- }
- connection.login("admin","admin","Rooyee");
- Presencepre=connection.getRoster().getPresence("shimiso@csdn.shimiso.com");
- System.out.println(pre);
- if(pre.getType()!=Presence.Type.unavailable){
- //创建文件传输管理器
- FileTransferManagermanager=newFileTransferManager(connection);
- //创建输出的文件传输
- OutgoingFileTransfertransfer=manager
- .createOutgoingFileTransfer(pre.getFrom());
- //发送文件
- transfer.sendFile(newFile("E:\\Chrysanthemum.jpg"),"图片");
- while(!transfer.isDone()){
- if(transfer.getStatus()==FileTransfer.Status.in_progress){
- //可以调用transfer.getProgress();获得传输的进度
- System.out.println(transfer.getStatus());
- System.out.println(transfer.getProgress());
- System.out.println(transfer.isDone());
- }
- }
- }
PPConnection.DEBUG_ENABLED = false; AccountManager accountManager; final ConnectionConfiguration connectionConfig = new ConnectionConfiguration( "192.168.1.78", Integer.parseInt("5222"), "csdn.shimiso.com"); // 允许自动连接 connectionConfig.setReconnectionAllowed(true); connectionConfig.setSendPresence(true); Connection connection = new XMPPConnection(connectionConfig); try { connection.connect();// 开启连接 accountManager = connection.getAccountManager();// 获取账户管理类 } catch (XMPPException e) { throw new IllegalStateException(e); } connection.login("admin", "admin","Rooyee"); Presence pre = connection.getRoster().getPresence("shimiso@csdn.shimiso.com"); System.out.println(pre); if (pre.getType() != Presence.Type.unavailable) { // 创建文件传输管理器 FileTransferManager manager = new FileTransferManager(connection); // 创建输出的文件传输 OutgoingFileTransfer transfer = manager .createOutgoingFileTransfer(pre.getFrom()); // 发送文件 transfer.sendFile(new File("E:\\Chrysanthemum.jpg"), "图片"); while (!transfer.isDone()) { if (transfer.getStatus() == FileTransfer.Status.in_progress) { // 可以调用transfer.getProgress();获得传输的进度 System.out.println(transfer.getStatus()); System.out.println(transfer.getProgress()); System.out.println(transfer.isDone()); } } }
运行结果:
在这里我们需要特别注意的是,跨资源是无法发送文件的,看connection.login("admin", "admin","Rooyee");这个代码就明白了,必须是“域名和资源名”完全相同的两个用户才可以互发文件,否则永远都没反应,如果不清楚自己所用的客户端的资源名,可以借助前面提到的SmackDebug工具查看往返信息完整报文,在to和from中一定可以看到。
如果我们自己要写文件接收例子的话,参考代码如下:
- FileTransferManagertransfer=newFileTransferManager(connection);
- transfer.addFileTransferListener(newRecFileTransferListener());
- publicclassRecFileTransferListenerimplementsFileTransferListener{
- publicStringgetFileType(StringfileFullName){
- if(fileFullName.contains(".")){
- return"."+fileFullName.split("//.")[1];
- }else{
- returnfileFullName;
- }
- }
- @Override
- publicvoidfileTransferRequest(FileTransferRequestrequest){
- System.out.println("接收文件开始.....");
- finalIncomingFileTransferinTransfer=request.accept();
- finalStringfileName=request.getFileName();
- longlength=request.getFileSize();
- finalStringfromUser=request.getRequestor().split("/")[0];
- System.out.println("文件大小:"+length+""+request.getRequestor());
- System.out.println(""+request.getMimeType());
- try{
- JFileChooserchooser=newJFileChooser();
- chooser.setCurrentDirectory(newFile("."));
- intresult=chooser.showOpenDialog(null);
- if(result==JFileChooser.APPROVE_OPTION){
- finalFilefile=chooser.getSelectedFile();
- System.out.println(file.getAbsolutePath());
- newThread(){
- publicvoidrun(){
- try{
- System.out.println("接受文件:"+fileName);

(7)用户头像的获取

(10)修改自身状态
包括上线,隐身,对某人隐身,对某人上线
- ublicstaticvoidupdateStateToAvailable(XMPPConnectionconnection)
- {
- Presencepresence=newPresence(Presence.Type.available);
- nnection.sendPacket(presence);
- publicstaticvoidupdateStateToUnAvailable(XMPPConnectionconnection)
- {
- Presencepresence=newPresence(Presence.Type.unavailable);
- nnection.sendPacket(presence);
- }
- publicstaticvoidupdateStateToUnAvailableToSomeone(XMPPConnectionconnection,StringuserName)
- {
- Presencepresence=newPresence(Presence.Type.unavailable);
- presence.setTo(userName);
- nnection.sendPacket(presence);
- }
- publicstaticvoidupdateStateToAvailableToSomeone(XMPPConnectionconnection,StringuserName)
- {
- Presencepresence=newPresence(Presence.Type.available);
- presence.setTo(userName);
- nnection.sendPacket(presence);
- }
ublic static void updateStateToAvailable(XMPPConnection connection) { Presence presence = new Presence(Presence.Type.available); nnection.sendPacket(presence); public static void updateStateToUnAvailable(XMPPConnection connection) { Presence presence = new Presence(Presence.Type.unavailable); nnection.sendPacket(presence); } public static void updateStateToUnAvailableToSomeone(XMPPConnection connection,String userName) { Presence presence = new Presence(Presence.Type.unavailable); presence.setTo(userName); nnection.sendPacket(presence); } public static void updateStateToAvailableToSomeone(XMPPConnection connection,String userName) { Presence presence = new Presence(Presence.Type.available); presence.setTo(userName); nnection.sendPacket(presence); }
(11)心情修改
- **
- *修改心情
- *@paramconnection
- *@paramstatus
- */
- publicstaticvoidchangeStateMessage(XMPPConnectionconnection,Stringstatus)
- {
- Presencepresence=newPresence(Presence.Type.available);
- presence.setStatus(status);
- connection.sendPacket(presence);
- }
** * 修改心情 * @param connection * @param status */ public static void changeStateMessage(XMPPConnection connection,String status) { Presence presence = new Presence(Presence.Type.available); presence.setStatus(status); connection.sendPacket(presence); }
(12)修改用户头像
有点麻烦,主要是读入图片文件,编码,传输之
- publicstaticvoidchangeImage(XMPPConnectionconnection,Filef)throwsXMPPException,IOException{
- VCardvcard=newVCard();
- vcard.load(connection);
- byte[]bytes;
- bytes=getFileBytes(f);
- StringencodedImage=StringUtils.encodeBase64(bytes);
- vcard.setAvatar(bytes,encodedImage);
- vcard.setEncodedImage(encodedImage);
- vcard.setField("PHOTO","<TYPE>image/jpg</TYPE><BINVAL>"
- +encodedImage+"</BINVAL>",true);
- ByteArrayInputStreambais=newByteArrayInputStream(
- vcard.getAvatar());
- Imageimage=ImageIO.read(bais);
- ImageIconic=newImageIcon(image);
- vcard.save(connection);
- }
- privatestaticbyte[]getFileBytes(Filefile)throwsIOException{
- BufferedInputStreambis=null;
- try{
- bis=newBufferedInputStream(newFileInputStream(file));
- intbytes=(int)file.length();
- byte[]buffer=newbyte[bytes];
- intreadBytes=bis.read(buffer);
- if(readBytes!=buffer.length){
- thrownewIOException("Entirefilenotread");
- }
- returnbuffer;
- }finally{
- if(bis!=null){
- bis.close();
- }
- }
- }
public static void changeImage(XMPPConnection connection,File f) throws XMPPException, IOException{ VCard vcard = new VCard(); vcard.load(connection); byte[] bytes; bytes = getFileBytes(f); String encodedImage = StringUtils.encodeBase64(bytes); vcard.setAvatar(bytes, encodedImage); vcard.setEncodedImage(encodedImage); vcard.setField("PHOTO", "<TYPE>image/jpg</TYPE><BINVAL>" + encodedImage + "</BINVAL>", true); ByteArrayInputStream bais = new ByteArrayInputStream( vcard.getAvatar()); Image image = ImageIO.read(bais); ImageIcon ic = new ImageIcon(image); vcard.save(connection); } private static byte[] getFileBytes(File file) throws IOException { BufferedInputStream bis = null; try { bis = new BufferedInputStream(new FileInputStream(file)); int bytes = (int) file.length(); byte[] buffer = new byte[bytes]; int readBytes = bis.read(buffer); if (readBytes != buffer.length) { throw new IOException("Entire file not read"); } return buffer; } finally { if (bis != null) { bis.close(); } } }
(13)用户状态的监听
即对方改变头像,状态,心情时,更新自己用户列表,其实这里已经有smack实现的监听器
- nalRosterroster=Client.getRoster();
- roster.addRosterListener(
- newRosterListener(){
- @Override
- publicvoidentriesAdded(Collection<String>arg0){
- //TODOAuto-generatedmethodstub
- System.out.println("--------EE:"+"entriesAdded");
- }
- @Override
- publicvoidentriesDeleted(Collection<String>arg0){
- //TODOAuto-generatedmethodstub
- System.out.println("--------EE:"+"entriesDeleted");
- }
- @Override
- publicvoidentriesUpdated(Collection<String>arg0){
- //TODOAuto-generatedmethodstub
- System.out.println("--------EE:"+"entriesUpdated");
- }
- @Override
- publicvoidpresenceChanged(Presencearg0){
- //TODOAuto-generatedmethodstub
- System.out.println("--------EE:"+"presenceChanged");
- }
- });
nal Roster roster = Client.getRoster(); roster.addRosterListener( new RosterListener() { @Override public void entriesAdded(Collection<String> arg0) { // TODO Auto-generated method stub System.out.println("--------EE:"+"entriesAdded"); } @Override public void entriesDeleted(Collection<String> arg0) { // TODO Auto-generated method stub System.out.println("--------EE:"+"entriesDeleted"); } @Override public void entriesUpdated(Collection<String> arg0) { // TODO Auto-generated method stub System.out.println("--------EE:"+"entriesUpdated"); } @Override public void presenceChanged(Presence arg0) { // TODO Auto-generated method stub System.out.println("--------EE:"+"presenceChanged"); } });
