【中文标题】java中如何通过Smack实现流管理？【英文标题】：how to implement Stream Management through Smack in java? 【发布时间】：2017-03-21 08:58:30 【问题描述】：如何使用 smack 4.1 中的 XEP 198（流管理）使用 java ，请分享一些参考。
我正在使用 java 代码将消息从 smack 发送到 spark
private static String username = "test";
private static String password = "test123";
public static class MessageParrot implements PacketListener
private XMPPConnection xmppConnection;
public MessageParrot(XMPPConnection conn)
xmppConnection = conn;
public void processPacket(Packet packet)
Message message = (Message)packet;
if(message.getBody() != null)
String fromName = StringUtils.parseBareAddress(message.getFrom());
System.out.println("Message from " + fromName + "\n" + message.getBody() + "\n");
Message reply = new Message();
reply.setTo(fromName);
reply.setBody("I am a Java bot. You said: " + message.getBody());
xmppConnection.sendPacket(reply);
public static void main(String[] args )
System.out.println("Starting IM client");
// gtalk requires this or your messages bounce back as errors
ConnectionConfiguration connConfig = new ConnectionConfiguration("domain.com", 5222);
XMPPConnection connection = new XMPPConnection(connConfig);
try
connection.connect();
System.out.println("Connected to " + connection.getHost());
catch (XMPPException ex)
//ex.printStackTrace();
System.out.println("Failed to connect to " + connection.getHost());
System.exit(1);
try
connection.login(username, password);
System.out.println("Logged in as " + connection.getUser());
Presence presence = new Presence(Presence.Type.available);
connection.sendPacket(presence);
catch (XMPPException ex)
//ex.printStackTrace();
// XMPPConnection only remember the username if login is succesful
// so we can''t use connection.getUser() unless we log in correctly
System.out.println("Failed to log in as " + username);
System.exit(1);
PacketFilter filter = new MessageTypeFilter(Message.Type.chat);
connection.addPacketListener(new MessageParrot(connection), filter);
/* if(args.length > 0) */
// google bounces back the default message types, you must use chat
Message msg = new Message("test2@domain.com", Message.Type.chat);
msg.setBody("hi");
// msg.addExtension(new DeliveryReceipt(msg.getPacketID()));
/* XhtmlExtension xhtmlExtension = new XHTMLExtension();
xhtmlExtension.addBody(
"<body>My lord, dispatch; read o'er these articles.</body><request xmlns='urn:xmpp:receipts'/>");
msg.addExtension(xhtmlExtension);*/
/* MessageEventManager.addNotificationsRequests(msg, true, true, true, true);
DeliveryReceiptManager.addDeliveryReceiptRequest(msg);*/
connection.sendPacket(msg);
System.out.println("Press enter to disconnect\n");
try
System.in.read();
catch (IOException ex)
//ex.printStackTrace();
connection.disconnect();
通过这个我可以和两个客户端聊天，一个来自 smack，另一个来自 spark，如何在这里实现流管理？
【问题讨论】：
【参考方案1】：创建连接对象后使用下面的代码
connection.setUseStreamManagement(true);
connection.setUseStreamManagementResumptionDefault(true);
之后查看<enable xmlns='urn:xmpp:sm:3' resume='true'/> 的日志，这意味着客户端想要使用流管理。服务器将响应此（如果支持）<enabled xmlns='urn:xmpp:sm:3' id='.......' resume='true' max='1'/>，这意味着流现已启用
完成后，如果您不断检查日志，您会发现 <r xmlns='urn:xmpp:sm:3'/> 和 <a xmlns='urn:xmpp:sm:3' h='1'/> 在客户端和服务器之间进行交换。
