本文介绍了一种将Flex与Spring框架集成的方法，并通过一个具体示例详细展示了集成过程。包括配置文件remoting-config.xml和服务配置文件services-config.xml的设置，以及如何在web.xml中初始化Spring上下文。

Flex和Spring的集成 -- 实例（一）

=============================================

remoting-config.xml：

<factory>spring</factory>

<source>springTest</source>

</properties>

</destination>

==============================================================

services-config.xml：

</factories>

==============================================================

web.xml：和struts整合spring一样

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>/WEB-INF/applicationContext.xml</param-value>

</context-param>

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

</listener>

============================================================

applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="springTest" class="flex.samples.SpringTest">
     <property name="description">
      <value>Hello </value>
     </property>
</bean>
</beans>

============================================================

SpringFactory.java文件

package flex.samples.factories;

import org.springframework.context.ApplicationContext;

import org.springframework.web.context.support.WebApplicationContextUtils;

import org.springframework.beans.BeansException;

import org.springframework.beans.factory.NoSuchBeanDefinitionException;

import flex.messaging.FactoryInstance;

import flex.messaging.FlexFactory;

import flex.messaging.config.ConfigMap;

import flex.messaging.services.ServiceException;

public class SpringFactory implements FlexFactory

{

private static final String SOURCE = "source";

public void initialize(String id, ConfigMap configMap) {}

public FactoryInstance createFactoryInstance(String id, ConfigMap properties)

{

SpringFactoryInstance instance = new SpringFactoryInstance(this, id, properties);

instance.setSource(properties.getPropertyAsString(SOURCE, instance.getId()));

return instance;

}

public Object lookup(FactoryInstance inst)

{

SpringFactoryInstance factoryInstance = (SpringFactoryInstance) inst;

return factoryInstance.lookup();

}

static class SpringFactoryInstance extends FactoryInstance

{

SpringFactoryInstance(SpringFactory factory, String id, ConfigMap properties)

{

super(factory, id, properties);

}

public String toString()

{

return "SpringFactory instance for id=" + getId() + " source=" + getSource() + " scope=" + getScope();

}

public Object lookup()

{

ApplicationContext appContext = WebApplicationContextUtils.getWebApplicationContext(flex.messaging.FlexContext.getServletConfig().getServletContext());

String beanName = getSource();

try

{

return appContext.getBean(beanName);

}

catch (NoSuchBeanDefinitionException nexc)

{

ServiceException e = new ServiceException();

String msg = "Spring service named '" + beanName + "' does not exist.";

e.setMessage(msg);

e.setRootCause(nexc);

e.setDetails(msg);

e.setCode("Server.Processing");

throw e;

}

catch (BeansException bexc)

{

ServiceException e = new ServiceException();

String msg = "Unable to create Spring service named '" + beanName + "' ";

e.setMessage(msg);

e.setRootCause(bexc);

e.setDetails(msg);

e.setCode("Server.Processing");

throw e;

}

=============================================

SpringTest.java

package flex.samples;

public class SpringTest {

private String description;

public String getDescription(String name) {
return description + name;
}

public void setDescription(String description) {
this.description = description;
}
}

=============================================

Flex.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.ResultEvent;
  function gg(evnet:ResultEvent):void{
   var ff:String = evnet.result as String;
   ggg.text = ff;
  }
  function remotingSayHello():void{
   var sname:String = nameInput.text;
   myspring.getDescription();
  }
  ]]>
</mx:Script>

<mx:RemoteObject id="myspring" destination="TestSpring" result="gg(event)" endpoint="http://localhost:8081/felx_spring/messagebroker/amf" />
