Java+Flex整合应用简单示例(mx:RemoteObject)

1.java

package com;

public class LoginDemo {
	
	public String validate(String username,String password){
		String message ="login failed!";
		if(username.equals("lin")&&password.equals("lin")){
			message = "login successed!";
		}
		return message;
	}

}

2.remoting-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<service id="remoting-service" 
    class="flex.messaging.services.RemotingService">

    <adapters>
        <adapter-definition id="java-object" class="flex.messaging.services.remoting.adapters.JavaAdapter" default="true"/>
    </adapters>

    <default-channels>
        <channel ref="my-amf"/>
    </default-channels>
    
    <destination id="login">
    	<properties>
    		<source>com.LoginDemo</source>
    	</properties>    
    </destination>
    
</service>

3.mxml

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
	<mx:Script>
		<![CDATA[
			import mx.rpc.events.FaultEvent;
			import mx.rpc.events.ResultEvent;
			import mx.controls.Alert;
			
			[Bindable]
			var returnValue:String;
			var username1:String;
			var password1:String;
			function sendRequest():void{
				username1=username.text;
				password1=password.text;				
				ro.validate(username1,password1);
				ro.addEventListener(ResultEvent.RESULT,results);
						
			}
			
			function results(event:ResultEvent):void{
				returnValue=event.result as String;
				
			}
			
			function faultHandler(event:FaultEvent):void{
				Alert.show(event.fault.toString());
			}
		]]>
	</mx:Script>
	
	<mx:RemoteObject id="ro" destination="login" fault="faultHandler(event)">
	</mx:RemoteObject>
	<mx:Panel height="400" width="400" layout="absolute" title="用户登录">
		<mx:Label x="50" y="50" text="用户名" width="50"></mx:Label>
		<mx:Label x="50" y="75" text="密码" width="50"></mx:Label>
		<mx:TextInput id="username" x="75" y="50"/>
		<mx:TextInput id="password" x="75" y="75"/>
		<mx:Button x="50" y="100" label="登录" click="sendRequest()"/>
