作用:初始化时在控制台打印测试消息。

开发环境：winxp/myeclipse6.5/jdk1.5&1.6/mysql5.0/openfire3.6.3 QQ群：28588322 (openfire专题研究小组)开发步骤：1. 布署openfire3.6.3源码（请参考openfire3.6.3导入eclipse项目实现方法) 结构如下：2. src/plugins目录下新建文件夹itvi。

并按下图的目录结构新建对应的文件。

plugin.xml文件代码如下：<?xml version="1.0" encoding="UTF-8"?><plugin><class>org.jivesoftware.openfire.plugin.Itvi</class><name>Itvi</name><description>Broadcasts messages to users.</description> <author>openfireteam</author><version>1.7.0</version><date>2/19/2009</date><url></url><minServerVersion>3.6.3</minServerVersion></plugin>Itvi.java文件代码如下：package org.jivesoftware.openfire.plugin;import org.dom4j.Element;import org.jivesoftware.openfire.IQHandlerInfo;import org.xmpp.packet.*;import org.jivesoftware.openfire.handler.IQHandler;import org.jivesoftware.openfire.auth.UnauthorizedException;/*** 处理客户端发来的IQ，并回送结果IQ** @author Phoenix** Mar 14, 2008 4:55:33 PM** version 0.1*/import org.dom4j.DocumentHelper;import org.dom4j.Element;import org.dom4j.QName;import org.jivesoftware.openfire.XMPPServer;import org.jivesoftware.openfire.container.Plugin;import org.jivesoftware.openfire.container.PluginManager; import org.jivesoftware.openfire.disco.IQDiscoInfoHandler; import org.jivesoftware.openfire.disco.IQDiscoItemsHandler; import org.jivesoftware.openfire.forms.DataForm;import org.jivesoftware.openfire.forms.FormField;import org.jivesoftware.openfire.forms.spi.XDataFormImpl; import org.jivesoftware.openfire.forms.spi.XFormFieldImpl; import org.jivesoftware.openfire.resultsetmanager.ResultSet; import org.jivesoftware.openfire.resultsetmanager.ResultSetImpl; import er;import erManager;import erNotFoundException; import org.jivesoftware.util.*;import ponent;import ponentException;import ponentManager;import ponentManagerFactory;import org.xmpp.packet.IQ;import org.xmpp.packet.IQ.Type;import org.xmpp.packet.JID;import org.xmpp.packet.Packet;import org.xmpp.packet.PacketError;import org.xmpp.packet.PacketError.Condition;import java.io.File;import java.util.*;import java.util.Map.Entry;public class Itvi implements Plugin{private XMPPServer server;/** (non-Javadoc)** @see org.jivesoftware.openfire.container.Plugin#destroyPlugin()*/public void destroyPlugin(){}/** (non-Javadoc)** @seeorg.jivesoftware.openfire.container.Plugin#initializePlugin(org.jivesoftware.openfir e.container.PluginManager,* java.io.File)*/public void initializePlugin(PluginManager manager, File pluginDirectory){server = XMPPServer.getInstance();server.getIQRouter().addHandler(new ItviIQHander()); //System.out.println("测试插件启动成功");}}ItviIQHander.java文件代码如下：package org.jivesoftware.openfire.plugin;import org.dom4j.Element;import org.jivesoftware.openfire.IQHandlerInfo;import org.xmpp.packet.*;import org.jivesoftware.openfire.handler.IQHandler;import org.jivesoftware.openfire.auth.UnauthorizedException;/*** 处理客户端发来的IQ，并回送结果IQ** @author Phoenix** Mar 14, 2008 4:55:33 PM** version 0.1*/public class ItviIQHander extends IQHandler{private static final String MODULE_NAME = "group tree handler";private static final String NAME_SPACE = "com:im:group";private IQHandlerInfo info;public ItviIQHander(){super(MODULE_NAME);//info = new IQHandlerInfo("gruops", NAME_SPACE);info = new IQHandlerInfo("query", "jabber:iq:roster");//这里我们对”联系人”的IQ进入监控}/** (non-Javadoc)** @see org.jivesoftware.openfire.handler.IQHandler#getInfo()*/@Overridepublic IQHandlerInfo getInfo(){return info;}/** (non-Javadoc)** @seeorg.jivesoftware.openfire.handler.IQHandler#handleIQ(org.xmpp.packet.IQ) */@Overridepublic IQ handleIQ(IQ packet) throws UnauthorizedException{IQ reply = IQ.createResultIQ(packet);Element groups = packet.getChildElement();//1if (true){System.out.println("非法的请求类型111111");}if (!IQ.Type.get.equals(packet.getType())){System.out.println("非法的请求类型");reply.setChildElement(groups.createCopy());System.out.println("返回的最终XML-SetError前"+reply.toXML());reply.setError(PacketError.Condition.bad_request);System.out.println("返回的最终XML-SetError后"+reply.toXML());return reply;}//String userName =StringUtils.substringBefore(packet.getFrom().toString(),"@");//GroupManager.getInstance().initElement(groups,userName); //reply.setChildElement(groups.createCopy());//2//System.out.println("返回的最终XML" reply.toXML());return reply;}}3.打包插件a.第一次打包需配置ant工具。
