red5 一些常用技巧

1. 配置多个webscope
将每一个应用配置到相应的XXX-web.xml 文件中，如下应用red5serv,增加red5serv-web.xml配置文件
 内容如下：
<bean id="web.context.red5serv" class="org.red5.server.Context">
  <property name="scopeResolver" ref="red5.scopeResolver" />
  <property name="clientRegistry" ref="global.clientRegistry" />
  <property name="serviceInvoker" ref="global.serviceInvoker" />
  <property name="mappingStrategy" ref="global.mappingStrategy" />
</bean>
 
<bean id="web.scope.red5serv" class="org.red5.server.WebScope" init-method="register">
  <property name="server" ref="red5.server" />
  <property name="parent" ref="global.scope" />
  <property name="context" ref="web.context.red5serv" />
  <property name="handler" ref="web.handler.red5serv" />
  <property name="contextPath" value="/red5serv" />
  <property name="virtualHosts" value="*,localhost, localhost:8888, 127.0.0.1:8888" />
</bean>
 
<bean id="web.handler.red5serv" class="red5.handler.MainHandler"></bean>

2.利用default scope共享数据

defaultContext.xml  配置文件中的Handler部分改成下面

<bean id="global.handler" class="red5.handler.DefaultHandler"/>

public class DefaultHandler extends CoreHandler {
 @Override
 public boolean start(IScope arg0) {
  if(firststart==0){
   arg0.getContext().getGlobalScope().setAttribute("default.scope", "defaultscope");
   
   log.info("init global");
   
  }
  firststart++;
  log.info(" DefaultHandler start " + arg0.getName() );
  arg0.setAttribute("currentscope", arg0.getName() + " ok");
  return super.start(arg0);
 }
}

每个应用启动前会先调用start方法.

3.在相同的scope 中 shareObject
java application handler

public void updateSO( Object[] value)
{
   so.beginUpdate();
      so.setAttribute( "test", value );
      so.endUpdate();
}

@Override
public boolean roomStart(IScope room) {
  log.info("roomStart ");

  
  if (!super.roomStart(room))
           return false;
    
  createSharedObject( room, "test", true );
     so = getSharedObject( room, "test" );
     so.addSharedObjectListener(new SampleSharedObjectListener());
     so.registerServiceHandler(new MySharedObjectHandler());
 
  log.info("roomStart test so");
  return true;
  
  
}

flex

public function onConnection():void{
    
   Logger.info("连接服务器成功，开始测试服务器方法");
   
    so = SharedObject.getRemote( "test", _nc.uri, true );
    so.client = this;
    so.connect( _nc );
    so.addEventListener( SyncEvent.SYNC, alertSO );
    
}
   
public function alertSO( e:SyncEvent = null ):void
{
 Alert.show( so.data.test.toString() );
}
   
public function sendSO( ):void
{
 _nc.call( "updateSO", null, ti.text );
}

<mx:TextInput id="ti" />
 
 <mx:Button label="send" click="sendSO()" x = "250"/>
 
 <mx:Button label="Aler Shared Object" click="alertSO()" x="500"/>

4.在jsp中直接访问red5服务器中的方法

<%
       String url = "http://localhost:8888/red5serv/gateway";
       RemotingClient client = new RemotingClient(url);
       Object[] args = new Object[]{"Hello world!"};
    
       client.invokeMethod(".getServerM", args, new IRemotingCallback(){
        public void errorReceived(RemotingClient client, String method,
                   Object[] params, Throwable error) {
         error.printStackTrace(); 
    
       }
    public void resultReceived(RemotingClient client, String method,
                       Object[] params, Object result) {
      System.out.print(result.toString());
    }
 
    });
%>
