Smack提供了一套发布订阅消息的功能API。代码如下：
发布：
package com.bis.pub;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smackx.pubsub.LeafNode;
import org.jivesoftware.smackx.pubsub.PayloadItem;
import org.jivesoftware.smackx.pubsub.PubSubManager;
import org.jivesoftware.smackx.pubsub.SimplePayload;
public class XmppPubsub_Publisher {
private static XMPPConnection connection = new XMPPConnection("wang-think");
private static String USRE_NAME = "t1";
private static String PASSWORD = "1";
static{
try {
connection.connect();
connection.login(USRE_NAME,PASSWORD);
} catch (Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args)throws Exception{
try{
PubSubManager manager = new PubSubManager(connection);
String nodeId = "zyf_test2";
LeafNode myNode = null;
try {
myNode = manager.getNode(nodeId);
} catch (Exception e) {
e.printStackTrace();
}
if(myNode == null){
myNode = manager.createNode(nodeId);
}
String msg = "fsadfasdfsadfasdfd---";
SimplePayload payload = new SimplePayload("message","pubsub:test:message", "<message xmlns='pubsub:test:message'><body>"+msg+"</body></message>");
PayloadItem<SimplePayload> item = new PayloadItem<SimplePayload>("5", payload);
myNode.publish(item);
System.out.println("-----publish-----------");
}
catch(Exception E)
{E.printStackTrace();}
}
}
