openfire ping的smack解决方案

SENT：<iq type="get" id="326-34" from="jacklin-pc" to="test002@jacklin-pc/XMPPTest"><ping xmlns="urn:xmpp:ping"/></iq>RECV：<iq id="326-34" to="jacklin-pc" from="test002@jacklin-pc/XMPPTest" type="result"></iq>

其中SENT的报文是服务器发送给客户端的，RECV是客户端收到服务器的报文后，回发给服务器的，此过程称之为ping-pong

在连接中关联如下：

                // iq提供者ProviderManager.getInstance().addIQProvider("ping", "urn:xmpp:ping",new PingIQProvider());connection.addPacketListener(new PacketListener() {@Overridepublic void processPacket(Packet p) {PingIQ pingIQ = (PingIQ) p;IQ pongIQ = pingIQ.createResultIQ(pingIQ);// 返回connection.sendPacket(pongIQ);}}, new PacketTypeFilter(PingIQ.class));

两个关联类，PingIQ，PingIQProvider

import org.jivesoftware.smack.packet.IQ;public class PingIQ extends IQ {public static final String ELEMENT = "ping";public static final String NAMESPACE = "urn:xmpp:ping";@Overridepublic String getChildElementXML() {StringBuffer sb = new StringBuffer();sb.append("<").append(ELEMENT).append(" xmlns=\"").append(NAMESPACE).append("\">");sb.append("</").append(ELEMENT).append(">");return sb.toString();}}

import org.jivesoftware.smack.packet.IQ;import org.jivesoftware.smack.provider.IQProvider;import org.xmlpull.v1.XmlPullParser;public class PingIQProvider implements IQProvider {@Overridepublic IQ parseIQ(XmlPullParser parser) throws Exception {// TODO Auto-generated method stubPingIQ iq = new PingIQ();return iq;}}

报文如下：

<iq xmlns="jabber:client" type="get" id="65dfds" from="localhost" to="test001@xmpp.qxun.org/test"><ping xmlns="urn:xmpp:ping"/></iq><iq type="result" to="localhost" id="65dfds"/>
