android openfire 插件开发：http://www.cnmsdn.com/html/201106/1308830174ID10035.html

Java代码  
实现功能，客户端发送一个IQ包含内容的节给服务器，服务器取得内容，然后广播给所有的在线用户  
  
新定义的iq为<iq id="xxx" type="set"><b xmlns="com:message:broadcasts">输入发言内容</b></iq>  
  
服务器端：  
建立org.jivesoftware.openfire.handler.IQHandler的实现类  

package test.plugin;    import org.dom4j.Element;  import org.jivesoftware.openfire.IQHandlerInfo;  import org.jivesoftware.openfire.XMPPServer;  import org.jivesoftware.openfire.auth.UnauthorizedException;  import org.jivesoftware.openfire.handler.IQHandler;  import org.xmpp.packet.IQ;    public class BroadcastsIQ extends IQHandler {        private IQHandlerInfo info;      public BroadcastsIQ() {          super("用户广播模块");          info = new IQHandlerInfo("b", "com:message:broadcasts");      }        @Override      public IQHandlerInfo getInfo() {          return info;      }        @Override      public IQ handleIQ(IQ packet) throws UnauthorizedException {          Element iq = packet.getElement();          Element b = iq.element("b");          String text = b.getText();          XMPPServer.getInstance().getSessionManager().sendServerMessage(null, text);//广播信息           return null;      }        }  

  
建立org.jivesoftware.openfire.container.Plugin的实现类  

package test.plugin;    import java.io.File;  import java.util.List;    import org.jivesoftware.openfire.XMPPServer;  import org.jivesoftware.openfire.container.Plugin;  import org.jivesoftware.openfire.container.PluginManager;  import org.jivesoftware.openfire.handler.IQHandler;    public class MyPlugin implements Plugin {        private IQHandler iQHandler;      @Override      public void destroyPlugin() {          XMPPServer.getInstance().getIQRouter().removeHandler(iQHandler);          System.out.println("插件停止成功");      }        @Override      public void initializePlugin(PluginManager manager, File pluginDirectory) {          iQHandler = new BroadcastsIQ();          XMPPServer.getInstance().getIQRouter().addHandler(iQHandler);          System.out.println("插件运行成功");      }  }  

  
建立plugin.xml文件  

<?xml version="1.0" encoding="UTF-8"?>  <plugin>      <class>test.plugin.MyPlugin</class>      <name>Broadcasts messages</name>      <description>This is an Broadcasts messages plugin.</description>      <author>me</author>        <version>1.0</version>      <date>01/01/2011/date>      <url>none</url>      <minServerVersion>3.0.0</minServerVersion>      <licenseType>gpl</licenseType>      <adminconsole>      </adminconsole>  </plugin>  

  
打包为任意名称的jar文件  
结构如下  
test.jar  
--classes  
  --test   
    --plugin  
      --BroadcastsIQ.class  
      --MyPlugin.class  
--META-INF  
  --MANIFEST.MF  
--plugin.xml  
  
  
  
然后把打好包的jar文件放到openfire的plugins目录下，openfire会自动加载，观察控制台是否输出 插件运行成功  
  
  
客户端：  
建立org.jivesoftware.smack.packet.IQ的实现类  

package test.xmpp;    import org.jivesoftware.smack.packet.IQ;    public class Broadcasts extends IQ {        private String body;      public String getElementName() {          return "b";      }        public String getNamespace() {          return "com:message:broadcasts";      }        public void setBody(String body) {          this.body = body;      }        public String getBody() {          return body;      }        @Override      public String getChildElementXML() {          if(getBody() == null){              throw new RuntimeException("Broadcasts body is empty");          }          StringBuilder sb = new StringBuilder();          sb.append("<").append(getElementName()).append(" xmlns=\"").append(getNamespace()).append("\">").append(getBody()).append("</").append(getElementName()).append(">");          return sb.toString();      }    }  

  
然后在程序中  
  

Broadcasts b = new Broadcasts();  b.setBody("测试广播内容");  b.setType(IQ.Type.SET);  conn.sendPacket(b);  

  
实现功能比较简单，算是学习openfire插件开发的开始吧
