本文详细介绍如何使用Java为OpenFire XMPP服务器开发插件，包括项目搭建、代码编写、Ant打包及配置文件创建等步骤。

1：新建一个web项目叫做plugin

2：在项目里面新建一个libs 文件夹，这个文件夹用来引入jar包。在这个包里面放入openfire.jar

3:开始编写代码我新建了两个类

      ImInterceptor   代码为：package com.im.plugin;

import org.jivesoftware.openfire.interceptor.PacketInterceptor;
import org.jivesoftware.openfire.interceptor.PacketRejectedException;
import org.jivesoftware.openfire.session.Session;
import org.xmpp.packet.Message;
import org.xmpp.packet.Packet;

public class ImInterceptor implements PacketInterceptor {

   public void interceptPacket(Packet packet, Session arg1, boolean arg2,
           boolean arg3) throws PacketRejectedException {
       System.out.println("packet:" + packet.toXML());
       if (packet instanceof Message) {
           Message msg = (Message) packet;
       }
   }

}

ImPlugin 代码为：

package com.im.plugin;

import org.jivesoftware.openfire.interceptor.PacketInterceptor;
import org.jivesoftware.openfire.interceptor.PacketRejectedException;
import org.jivesoftware.openfire.session.Session;
import org.xmpp.packet.Message;
import org.xmpp.packet.Packet;

public class ImInterceptor implements PacketInterceptor {

   public void interceptPacket(Packet packet, Session arg1, boolean arg2,
           boolean arg3) throws PacketRejectedException {
       System.out.println("packet:" + packet.toXML());
       if (packet instanceof Message) {
           Message msg = (Message) packet;
       }
   }

}

4：这个时候需要通过ant打包所以在项目线面要写一个build.xml 内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<project name="IM" default="release" basedir=".">
   <property name="openfire.path" value="C:/Users/XXX/Desktop" />
   <property name="classes.dir" value="classes" />
   <property name="lib.dir" value="lib" />
   <target name="jar">
       <mkdir dir="${classes.dir}" />
       <mkdir dir="${lib.dir}" />
       <javac srcdir="src" destdir="${classes.dir}">
           <classpath>
               <fileset dir="libs">
                   <include name="*.jar" />
               </fileset>
           </classpath>
       </javac>
       <jar jarfile="${lib.dir}/grouptreeplugin.jar" basedir="${classes.dir}">
           <fileset dir=".">
               <include name="*.jar" />
           </fileset>
       </jar>
       <echo message=" iminterceptor ${openfire.path}" />
       <jar jarfile="${openfire.path}/groupTreePlugin.jar">
           <fileset dir=".">
               <include name="lib/*.jar" />
               <include name="plugin.xml" />
               <include name="build.xml" />
           </fileset>
       </jar>
   </target>
   <target name="release" depends="jar">
   </target>
</project>

5:还要写一个plugin.xml

<?xml version="1.0" encoding="UTF-8"?>
<plugin>

<class>com.xopenfire.org.DPluginTest</class>

<name>GroupTreePlugin</name>
<description>This is the inttercept plugin.</description>
