手把手教你使用flex eclipse整合spring

最先下载FlashBuilder_4_7_LS10_win64.exe试了几个eclipse安装插件都没成功，包括myeclipse8.5、spring sts2.9.2、eclipse3.5、j2eeeclipse版本4.2.0，后来搞了一个FlashBuilder_4_LS10.exe安装完找不到插件安装文件原来这个是单独版，必须插件版才行，最后下载FlashBuilder_4_Plugin_LS10.exe终于配置成功了，myeclipse8.5不行，spring sts可以了。

spring sts部署应用跟myeclipse不一样，比较类似eclipse。

用sts整合flex和java有几个步骤：

1：新建动态web工程flexweb，创建web.xml

2： blazeds-turnkey-4.0.0.14931.zip解压， 复制blazed两个文件夹flex和lib到WEB-INF下，里面是blaze的jar包和flex配置文件，然后修改web.xml加入blaze支持

<listener> <listener-class>flex.messaging.HttpFlexSession</listener-class> </listener> <!-- MessageBroker Servlet --> <servlet> <servlet-name>MessageBrokerServlet</servlet-name> <servlet-class>flex.messaging.MessageBrokerServlet</servlet-class> <init-param> <param-name>services.configuration.file</param-name> <param-value>/WEB-INF/flex/services-config.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>MessageBrokerServlet</servlet-name> <url-pattern>/messagebroker/*</url-pattern> </servlet-mapping>

3：项目右键，添加/更改项目类型>添加flex类型项目，第一步，应用程序类型选择J2EE，下方选择BlazeDS，第二部根文件夹填入项目在workspase的路径加一个WebContent，如E:workspacesstsflexwebWebContent，根URL填:8080/flexweb，上下文根目录/flexweb，输出文件夹使用默认E:workspacesstsflexwebWebContentflexweb-debug，点击finish
4：转换完成后，目录有些变化，右键项目>properties>flex构建路径，主源文件夹改为flex_src，然后把自动生成的src目录下的flexweb.mxml移动到flex_src下，环境搭建就算完成了

HelloWorld

flexweb.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/mx" minWidth="955" minHeight="600"> <fx:Script> <![CDATA[ import mx.controls.Alert; import mx.rpc.events.ResultEvent; protected function myFlex_resultHandler(event:ResultEvent):void{ var name:String=event.result as String; Alert.show(name); } protected function button1_clickHandler(event:MouseEvent):void { myFlex.sayHello(txtName.text); } ]]> </fx:Script> <fx:Declarations> <!-- 将非可视元素（例如服务、值对象）放在此处 --> <s:RemoteObject destination="mytest" result="myFlex_resultHandler(event)"/> </fx:Declarations> <s:Button x="209" y="135" label="按钮"/> <s:TextInput x="166" y="81"/> <s:Label x="10" y="81" text="请输入内容：" fontSize="15" fontWeight="bold" fontFamily="中易黑体"/> </s:Application>

其中

<s:RemoteObject destination="mytest" result="myFlex_resultHandler(event)"/>

指定了一个调用Java的类Hello，mytest对应到remoting-config.xml

在WEB-INFO/flex目录下remoting-config.xml加入

<destination> <properties> <source>com.hongbo.Hello</source> </properties> </destination>

result对应的是java方法调用的回调函数
建一个普通java类

package com.hongbo; public class Hello { public String sayHello(String name){ System.out.println("------------------------------------"); return "Hello First Demo " + name; } }

这样就OK了

访问路径是:8080/flexweb/flexweb-debug/flexweb.html

第一次会报404，problems提示无法创建html包装器，右键点击重新创建模板

添加Spring支持

1：web.xml加入

<context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/applicationContext.xml </param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>

2：src下创建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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"> <bean> <property> <ref bean="testSpring"/> </property> </bean> <bean/> </beans>

3：WEB-INF/flex/service-config.xml加入

<factories> <factory /> </factories>

添加java类

package com.hongbo; 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.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; } // end method createFactoryInstance() 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 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; } } } }

4：修改remoting-config.xml

<destination> <properties> <factory>spring</factory> <source>hello</source> </properties> </destination>

5：修改相应的Java类
