Spring+flex（Blazeds）註解方式創建項目

轉自：http://szydnjw.javaeye.com/blog/852134

本人第一次發表文章，如有不妥，請指正。
   進入正題，spring+flex網上方法很多，但用註解的文章很少，現用註解的方式配置一個簡單的實例。
   所用的開發環境eclipse3.5+flex4+spring3+blazeds(4.0.1.17657)
   ps:Blazeds版本最低爲4.0.1.17657+
   因爲用Blazeds所以SPRING就不必專門去下載了。先創建個基本FLEX+java的項目，相信大家一定多會。不會的去網上找下，一大推。主要是在讓我們選擇 blazeds war文件時，我們選擇blazeds-spring.war（版本4.0.1.17657+）這樣就自動把所有的JAR包多放到lib包下了包括SPRING的。

首先配置WEB.XML

Java代碼

    </resource-ref>
    -->

</web-app>

接着創建FLEX APP命名隨便，我現在命名爲index.mxml,代碼如下

Java代碼

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">
<s:layout>
<s:BasicLayout/>
</s:layout>
<fx:Script>
<![CDATA[
import mx.controls.Alert;
import mx.rpc.events.ResultEvent;
protected function button1_clickHandler(event:MouseEvent):void
{
service.firstApp("Flex");
}
protected function remote_resultHandler(event:ResultEvent):void
{
Alert.show(String(event.result));
}
]]>
</fx:Script>
<fx:Declarations>
<s:RemoteObject id="service" destination="myService" result="remote_resultHandler(event)" endpoint="messagebroker/amf"/>
</fx:Declarations>
<s:Button x="72" y="101" label="按鈕" click="button1_clickHandler(event)"/>
</s:Application>

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
			   xmlns:s="library://ns.adobe.com/flex/spark" 
			   xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">
	<s:layout>
		<s:BasicLayout/>
	</s:layout>




	<fx:Script>
		<![CDATA[
			import mx.controls.Alert;
			import mx.rpc.events.ResultEvent;
			
			protected function button1_clickHandler(event:MouseEvent):void
			{
				service.firstApp("Flex");
			}
			protected function remote_resultHandler(event:ResultEvent):void
			{
				Alert.show(String(event.result));
			}
		]]>
	</fx:Script>

	<fx:Declarations>
		<!-- 將非可視元素（例如服務、值對象）放在此處 -->
		<s:RemoteObject id="service" destination="myService" result="remote_resultHandler(event)" endpoint="messagebroker/amf"/>
	</fx:Declarations>
	<s:Button x="72" y="101" label="按鈕" click="button1_clickHandler(event)"/>
</s:Application>

接着是JAVA端程序
MyService.java

Java代碼

package com.test.service;
import org.springframework.flex.remoting.RemotingDestination;
import org.springframework.flex.remoting.RemotingInclude;
import org.springframework.stereotype.Service;
@Service("myService")
@RemotingDestination(channels = { "my-amf", "my-secure-amf" })
public class MyService {
@RemotingInclude
public String firstApp(String info){
System.out.println(info);//從FLEX端獲取的信息
return "Hello World "+info;//返回給FLEX
}
}

package com.test.service;

import org.springframework.flex.remoting.RemotingDestination;
import org.springframework.flex.remoting.RemotingInclude;
import org.springframework.stereotype.Service;


@Service("myService")
@RemotingDestination(channels = { "my-amf", "my-secure-amf" })
public class MyService {
	
	@RemotingInclude
	public String firstApp(String info){
		
		System.out.println(info);//從FLEX端獲取的信息
		
		return "Hello World "+info;//返回給FLEX
		
	}

}

   然後我們在WebContent/WEB-INF/spring下，修改app-config.xml SPRING配置文件。該文件是在選擇BLAZEDS-SPRING.WAR後自動生成的。
   修改後的 app-config.xml

Java代碼

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:security="http://www.springframework.org/schema/security"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="

http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:component-scan base-package="com.test.service" />
<context:annotation-config />
</beans>

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:security="http://www.springframework.org/schema/security"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
		http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

	<context:component-scan base-package="com.test.service" />
	<context:annotation-config />
</beans>

好了，啓動TOMCAT，然後輸入地址，我的是
http://localhost:9090/oa/index.html
應該前後臺多有東西輸出了吧！祝大家好運！
