環(huán)境：
jdk1.6
j2ee1.5
spring2.5.6
blazeDS3.3
tomcat6.0
flex4
myeclipse8.5
flashBuilder4
步驟：
一、 啟動(dòng)好blazeDS(即啟動(dòng)tomcat，在[tomcat]/webapps目錄下產(chǎn)生一個(gè)blazeds文件夾(三個(gè)war包產(chǎn)生一個(gè)blazeds文件夾))；
在myeclipse8.5新建一個(gè)web Project工程，工程名為webSpring；
把此工程加入blazeDS支持(即用blazeds下的WEB-INF文件夾替換掉web工程下的WEB-INF文件夾)；
加入spring支持(把spring相關(guān)的jar包拷貝到webSpring/WebRoot/WEB-INF/lib目錄下即可)。
二、 1. 在javaWeb工程webSpring的str目錄下分別新建一下兩個(gè)包：
cn.xuediit.myFactory、cn.xuediit.myService；
2. 在cn.xuediit.myFctory包下新建兩個(gè)類：FlexFactoryImpl.java和SpringFactoryInstance.java
(1). FlexFactoryImpl.java：
package cn.xuediit.myFactory;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import flex.messaging.FactoryInstance;
import flex.messaging.FlexFactory;
import flex.messaging.config.ConfigMap;
public class FlexFactoryImpl implements FlexFactory {
private Log log = LogFactory.getLog(getClass());
/*override interface method*/
public void initialize(String id, ConfigMap configMap) {
System.out.println("1---flex工廠實(shí)現(xiàn)類重寫的方法initialize");
}
/*override interface method*/
public FactoryInstance createFactoryInstance(String id, ConfigMap properties) {
System.out.println("2---flex工廠實(shí)現(xiàn)類重寫的方法createFactoryInstance");
log.info("Create FactoryInstance.");
SpringFactoryInstance instance = new SpringFactoryInstance(this, id, properties);
instance.setSource(properties.getPropertyAsString(SOURCE, instance.getId()));
return instance;
}
/*override interface method*/
public Object lookup(FactoryInstance instanceInfo) {
System.out.println("4---flex工廠實(shí)現(xiàn)類重寫的方法lookup");
log.info("Lookup service object.");
return instanceInfo.lookup();
}
}
(2).SpringFactoryInstance.java
package cn.xuediit.myFactory;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.NoSuchBeanDefinitionException;
import org.springframework.context.ApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;
import flex.messaging.FactoryInstance;
import flex.messaging.FlexContext;
import flex.messaging.FlexFactory;
import flex.messaging.config.ConfigMap;
import flex.messaging.services.ServiceException;
public class SpringFactoryInstance extends FactoryInstance {
private Log log = LogFactory.getLog(getClass());
SpringFactoryInstance(FlexFactory factory, String id, ConfigMap properties) {
super(factory, id, properties);
}
public Object lookup() {
System.out.println("3---spring工廠類的方法lookup");
ApplicationContext appContext = WebApplicationContextUtils.getRequiredWebApplicationContext(FlexContext.getServletConfig().getServletContext());
String beanName = getSource();
try {
log.info("Lookup bean from Spring ApplicationContext: " + beanName);
return appContext.getBean(beanName);
} catch (NoSuchBeanDefinitionException nex) {
ServiceException e = new ServiceException();
String msg = "Spring service named '" + beanName + "' does not exist.";
e.setMessage(msg);
e.setRootCause(nex);
e.setDetails(msg);
e.setCode("Server.Processing");
throw e;
} catch (BeansException bex) {
ServiceException e = new ServiceException();
String msg = "Unable to create Spring service named '" + beanName + "'.";
e.setMessage(msg);
e.setRootCause(bex);
e.setDetails(msg);
e.setCode("Server.Processing");
throw e;
} catch (Exception ex) {
ServiceException e = new ServiceException();
String msg = "Unexpected exception when trying to create Spring service named '" + beanName + "'.";
e.setMessage(msg);
e.setRootCause(ex);
e.setDetails(msg);
e.setCode("Server.Processing");
throw e;
}
}
}
3. 在cn.xuediit.myService包下新建兩個(gè)類：FService.java和FServicesImpl.java
(1). FService.java
package cn.xuediit.myService;
public interface FService {
public String sayHello(String name);
}
(2). FServicesImpl.java
package cn.xuediit.myService;
public class FServicesImpl implements FService {
public String sayHello(String name) {
System.out.println("5---服務(wù)層實(shí)現(xiàn)類（本質(zhì)上的與flex交互的類）");
return "我是服務(wù)層的服務(wù)實(shí)現(xiàn)類==" + name;
}
}
三、 1、 在javaWeb工程webSpring下，在文件webSpring/WebRoot/WEB-INF/web.xml的<web-app>標(biāo)簽下添加子節(jié)點(diǎn)：
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
2、 在javaWeb工程webSpring下，在webSpring/WebRoot/WEB-INF目錄下新建一個(gè)文件：applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">
<bean id="fServiceImplBeanID" class="cn.xuediit.myService.FServicesImpl"></bean>
</beans>
四、 1、 在javaWeb工程webSpring下，在WebRoot/WEB-INF/flex/remoting-config.xml文件中的<service>標(biāo)簽下添加：
<destination id="destinationID">
<properties>
<factory>flexFactoryImplID</factory>
<source>fServiceImplBeanID</source>
<scope>application</scope>
</properties>
</destination>
2、 在javaWeb工程webSpring下，在WebRoot/WEB-INF/flex/services-config.xml文件中的<services-config>標(biāo)簽下添加：
<factories>
<factory id="flexFactoryImplID" class="cn.xuediit.myFactory.FlexFactoryImpl"/>
</factories>
五、 給此javaWeb工程添加tomcat支持，啟動(dòng)tomcat（這個(gè)容易就不說了）。
六、 在flashBuilder下新建一個(gè)基于blazeDS的flex項(xiàng)目(以webSpring為后臺(tái)工程)，工程名為webFb；
webFb.mxml：
<?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/halo"
minWidth="500" minHeight="200">
<fx:Script>
<![CDATA[
import mx.core.Application;
import mx.rpc.events.FaultEvent;
import mx.collections.ArrayCollection;
import mx.rpc.remoting.mxml.RemoteObject;
import mx.controls.Alert;
import mx.rpc.events.ResultEvent;
public function submit(name:String):void{
var remote:RemoteObject = new RemoteObject();
remote.destination = "destinationID";
remote.endpoint = "http://localhost:8080/webSpring/messagebroker/amf";
remote.addEventListener(ResultEvent.RESULT, myResult);
remote.addEventListener(FaultEvent.FAULT,fault);
remote.sayHello(name);
}
private function myResult(evt:ResultEvent):void{
Alert.show(evt.result.toString());
}
private function fault(evt:FaultEvent):void{
Alert.show(evt.fault.message);
}
]]>
</fx:Script>
<s:Button x="240" y="11" label="要發(fā)送到" click="submit(nameTxt.text)"/>
<s:Label x="16" y="11" text="姓名"/>
<s:TextInput id="nameTxt" x="100" y="100"/>
</s:Application>
七、 重啟tomcat，運(yùn)行flex程序，如彈出：我是服務(wù)層的服務(wù)實(shí)現(xiàn)類==(輸入框的內(nèi)容)，則成功。
