JAVA和Flex敏捷调用(二)

    Flex在和java调用过程中，其实有更加灵活的办法来提高系统的敏捷度，极大提高系统的耦合和开发效率。在这里我继续给大家介绍一下，敏捷调用中的java动态代码调用。
    先看java的类(BeanShell)这里主要是接收java代码来动态调用的
    package com.shine.framework.beanShell;
import bsh.Interpreter;
public class BeanShell {
public Object executBeanShell(String code) {
try {
Interpreter inter = new Interpreter();
inter.eval(code);
return inter.get("result");
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
}
   然后把该类配置到remoting-config.xml
  <destination id="beanShell">
<properties>
<source>com.shine.framework.beanShell.BeanShell</source>
</properties>
</destination>
  再写一个静态的beanShell在actionscript，以单例模式
  package com.shine.framework.beanShell
{
import mx.rpc.events.FaultEvent;
import mx.rpc.events.ResultEvent;
import mx.rpc.remoting.mxml.RemoteObject;
import mx.controls.Alert;
public class BeanShell
{
private static var _instance:BeanShell;
private var method:Function;
public function BeanShell(enforcer:SingletonEnforcer)
{
}
public static function getInstance():BeanShell
{
if (BeanShell._instance == null)
{
BeanShell._instance=new BeanShell(new SingletonEnforcer());
}
return BeanShell._instance;
}
public function beanShell(code:String, method:Function=null):void
{
this.method=method;
var beanShell:RemoteObject=new RemoteObject;
beanShell.destination="beanShell";
beanShell.addEventListener(FaultEvent.FAULT, error);
beanShell.endpoint="messagebroker/amf";
beanShell.executBeanShell(code);
beanShell.addEventListener(ResultEvent.RESULT, getRomoteHelloRes);
}
private function getRomoteHelloRes(e:ResultEvent):void
{
if(this.method!=null){
this.method.call(this, e.result);
}
}
