基于openfire源码开发插件
小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
【0】README
1）本文旨在 簡述如何 基于openfire源碼開發(fā)插件， 如何導(dǎo)入 openfire源碼到 eclipse，參見?http://blog.csdn.net/pacosonswjtu/article/details/51871622
2）also , you can checkout ?source code of the plugin from ?https://github.com/pacosonTang/MultimediaMessagingPlatform/tree/master/plugin_cluster/plugindemo/src
【1】開發(fā)openfire插件步驟 step1）建立插件目錄樹（插件名稱==plugindemo）
補(bǔ)充1）各個(gè)目錄樹的目錄項(xiàng)的意義：
補(bǔ)充2）目錄樹的縮略圖如下
step2）添加 java 根目錄到 source folder
step3）開發(fā)openfire插件，實(shí)現(xiàn) Plugin接口
package com.myplugin;import java.io.File;import org.jivesoftware.openfire.container.Plugin; import org.jivesoftware.openfire.container.PluginManager; import org.jivesoftware.openfire.interceptor.InterceptorManager; import org.jivesoftware.openfire.interceptor.PacketInterceptor; import org.jivesoftware.openfire.interceptor.PacketRejectedException; import org.jivesoftware.openfire.session.Session; import org.xmpp.packet.Packet;// 如果需要攔截消息，就必須實(shí)現(xiàn) PacketInterceptor public class PluginDemo implements PacketInterceptor, Plugin{private static PluginManager pluginManager;private InterceptorManager interceptorManager;public PluginDemo() {interceptorManager = InterceptorManager.getInstance();}@Overridepublic void interceptPacket(Packet packet, Session session,boolean incoming, boolean processed) throws PacketRejectedException {System.out.println("攔截消息以進(jìn)行邏輯處理" + "from =" + packet.getFrom() + ", to = " + packet.getTo() + ", incoming = " + incoming + ", proccessed = " + processed);System.out.println("\n=========================");}@Overridepublic void destroyPlugin() {interceptorManager.removeInterceptor(this);System.out.println("PluginDemo Plugin has been destroyed.");}@Overridepublic void initializePlugin(PluginManager manager, File pluginDirectory) {interceptorManager.addInterceptor(this);pluginManager = manager; System.out.println("PluginDemo Plugin has been installed successfully.");} } step4）可選的，如果你覺得有必要的話，還可以在插件中嵌入 servlet；
package com.myplugin.manager;import java.io.IOException; import java.io.PrintWriter;import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;public class PluginDemoServlet extends HttpServlet{@Overrideprotected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {response.setContentType("text/plain");PrintWriter out = response.getWriter();System.out.println("console info: 請求SampleServlet GET Method");out.println("GET Method: these info are transmitted into client.");out.flush();}@Overrideprotected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {// super.doPost(request, response); // should be commented outresponse.setContentType("text/plain");PrintWriter out = response.getWriter();System.out.println("請求 PluginDemoServlet POST Method");out.print("請求 PluginDemoServlet POST Method");out.flush();}@Overridepublic void init() throws ServletException {System.out.println("servlet init successfully.");} } step4）補(bǔ)充： 添加servlet映射
