(转)red5视频聊天源码

忙了好几天，最近也算把Red5服务器服务端基本搞定了。
    为了熟悉服务端代码，以及了解API，我仿照着FMS的模式做了一个多人聊天室。基本实现了视频、群聊、私聊几个基本功能。看到网上似乎还没有人放出这类的源代码，我索性就先当回螃蟹吧！
　　我们先来看代码：
　　服务端：
　　Application.java
　　

package org.jerry.videochat;

import java.util.*;
import org.red5.server.adapter.ApplicationAdapter;
import org.red5.server.api.IConnection;
import org.red5.server.api.IScope;
import org.red5.server.api.service.IServiceCapableConnection;
import org.red5.server.api.so.ISharedObject;

public class Application extends ApplicationAdapter {
// 属性
private IScope appScope;

private String username;

private ISharedObject listSO;

private ISharedObject msgSO;

private Map<String, IConnection> onLineClient = new HashMap<String, IConnection>();

// 方法
// 此应用开始运行时触发的方法
public boolean appStart(IScope app) {
   if (!super.appStart(app)) {
    return false;
   }
   appScope = app;
   return true;
}

// 客户端连接的时候触发的方法
public boolean appConnect(IConnection conn, Object[] params) {
   username = (String) params[0];
   // 登入时将连接ID和连接信息形成对应关系并存入在线列表
   String link_id = conn.getClient().getId();
   onLineClient.put(username, conn);
   // 为用户列表共享对象添加属性
   // 创建用户列表共享对象
   listSO = getSharedObject(appScope, "listSO", false);
   // 创建用户聊天内容共享对象
   msgSO = getSharedObject(appScope, "msgSO", false);
   listSO.setAttribute(link_id, username);
   return true;
}

// 广播消息
public void broadcastUserMsg(String msg) {
   // 公聊
   // 刷新共享对象属性
   msgSO.setAttribute("msg", msg);
}

// 私聊信息
public void msgFromPrivate(String msg, String from, String to) {
   IServiceCapableConnection fc = (IServiceCapableConnection) onLineClient
     .get(from);
   IServiceCapableConnection tc = (IServiceCapableConnection) onLineClient
     .get(to);
   fc.invoke("showMsgByPrivate", new Object[] { msg });
   tc.invoke("showMsgByPrivate", new Object[] { msg });
}

// 用户断开连接的时候触发
public void appDisconnect(IConnection conn) {
   String dis_link_id = conn.getClient().getId();
   String user = (String) listSO.getAttribute(dis_link_id);
   // 根据ID删除对应在线纪录
   onLineClient.remove(user);
   // 删除用户列表共享对象的对应属性
   listSO.removeAttribute(dis_link_id);
}
}
