Spring+flex（Blazeds）注解方式创建项目

本人第一次发表文章，如有不妥，请指正。
   进入正题，spring+flex网上方法很多，但用注解的文章很少，现用注解的方式配置一个简单的实例。
   所用的开发环境eclipse3.5+flex4+spring3+blazeds(4.0.1.17657)
   ps:Blazeds版本最低为4.0.1.17657+
   因为用Blazeds所以SPRING就不必专门去下载了。先创建个基本FLEX+java的项目，相信大家一定多会。不会的去网上找下，一大推。主要是在让我们选择 blazeds war文件时，我们选择blazeds-spring.war（版本4.0.1.17657+）这样就自动把所有的JAR包多放到lib包下了包括SPRING的。

  首先配置WEB.XML

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>

    <display-name>BlazeDS Spring Integration Application</display-name>
    <description>BlazeDS Spring Integration Application</description>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            /WEB-INF/spring/infrastructure-config.xml, 
            /WEB-INF/spring/security-config.xml,
            /WEB-INF/spring/app-config.xml
        </param-value>
    </context-param>
    
    <filter>
        <filter-name>springSecurityFilterChain</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>

    <filter-mapping>
      <filter-name>springSecurityFilterChain</filter-name>
      <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- Http Flex Session attribute and binding listener support -->
    <listener>
        <listener-class>flex.messaging.HttpFlexSession</listener-class>
    </listener>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- Spring Dispatcher Servlet -->   
    <servlet>
        <servlet-name>flex</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

<!-- begin rds
    <servlet>
        <servlet-name>RDSDispatchServlet</servlet-name>
        <display-name>RDSDispatchServlet</display-name>
        <servlet-class>flex.rds.server.servlet.FrontEndServlet</servlet-class>
        <init-param>
            <param-name>useAppserverSecurity</param-name>

        <init-param>

			<param-value>_messageBroker</param-value>
		</init-param>
        <load-on-startup>10</load-on-startup>
    </servlet>

    <servlet-mapping id="RDS_DISPATCH_MAPPING">
        <servlet-name>RDSDispatchServlet</servlet-name>
        <url-pattern>/CFIDE/main/ide.cfm</url-pattern>
    </servlet-mapping>
end rds -->

    <servlet-mapping>
        <servlet-name>flex</servlet-name>
        <url-pattern>/messagebroker/*</url-pattern>
     </servlet-mapping>

    <welcome-file-list>
        <welcome-file>index.html</welcome-file>

    <!-- for WebSphere deployment, please uncomment -->
    <!--

        <res-auth>Container</res-auth>
        <res-sharing-scope>Shareable</res-sharing-scope>
    </resource-ref>
    -->

</web-app>

    接着创建FLEX APP命名随便，我现在命名为index.mxml,代码如下

<?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>
		<!-- 将非可视元素（例如服务、值对象）放在此处 -->
		<s:RemoteObject id="service" destination="myService" result="remote_resultHandler(event)" endpoint="messagebroker/amf"/>
	</fx:Declarations>
	<s:Button x="72" y="101" label="按钮" click="button1_clickHandler(event)"/>
</s:Application>

   接着是JAVA端程序
   MyService.java

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);//从FLEX端获取的信息
		
		return "Hello World "+info;//返回给FLEX
		
	}

}

   然后我们在WebContent/WEB-INF/spring下，修改app-config.xml SPRING配置文件。该文件是在选择BLAZEDS-SPRING.WAR后自动生成的。
   修改后的 app-config.xml
  

<?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="

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

    好了，启动TOMCAT，然后输入地址，我的是

  应该前后台多有东西输出了吧！祝大家好运！
