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、springsts2.9.2、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，springsts可以了。

springsts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>


<!--MessageBrokerServlet-->
<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:\workspaces\sts\flexweb\WebContent，根URL填http://localhost:8080/flexweb，上下文根目录/flexweb，输出文件夹使用默认E:\workspaces\sts\flexweb\WebContent\flexweb-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：

<?xmlversion="1.0"encoding="utf-8"?>
<s:Applicationxmlns: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[
importmx.controls.Alert;
importmx.rpc.events.ResultEvent;

protectedfunctionmyFlex_resultHandler(event:ResultEvent):void{
varname:String=event.resultasString;
Alert.show(name);
}
protectedfunctionbutton1_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:RemoteObjectid="myFlex"destination="mytest"result="myFlex_resultHandler(event)"/>
</fx:Declarations>
<s:Buttonx="209"y="135"label="按钮"click="button1_clickHandler(event)"/>
<s:TextInputx="166"y="81"id="txtName"/>
<s:Labelx="10"y="81"text="请输入内容："fontSize="15"fontWeight="bold"fontFamily="中易黑体"/>
</s:Application>

其中

<s:RemoteObjectid="myFlex"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

<destinationid="mytest">
<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

packagecom.hongbo;

publicclassHello{

publicStringsayHello(Stringname){
System.out.println("------------------------------------");
return"HelloFirstDemo"+name;
}
}

这样就OK了

访问路径是http://localhost: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

<?xmlversion="1.0"encoding="UTF-8"?>
<beansxmlns="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/beanshttp://www.springframework.org/schema/beans/spring-beans-2.0.xsd
http://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-2.0.xsd
http://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-2.0.xsd">

<beanid="hello"class="com.hongbo.Hello">
<propertyname="testSpring">
<refbean="testSpring"/>
</property>
</bean>
<beanid="testSpring"class="com.hongbo.test.impl.TestSpringImpl"/>
</beans>

3：WEB-INF/flex/service-config.xml加入

<factories>
<factoryid="spring"class="com.hongbo.SpringFactory"/>
</factories>

添加java类

packagecom.hongbo;


importorg.springframework.beans.BeansException;
importorg.springframework.beans.factory.NoSuchBeanDefinitionException;
importorg.springframework.context.ApplicationContext;
importorg.springframework.web.context.support.WebApplicationContextUtils;
importflex.messaging.FactoryInstance;
importflex.messaging.FlexFactory;
importflex.messaging.config.ConfigMap;
importflex.messaging.services.ServiceException;
publicclassSpringFactoryimplementsFlexFactory{
privatestaticfinalStringSOURCE="source";

publicvoidinitialize(Stringid,ConfigMapconfigMap){
}

publicFactoryInstancecreateFactoryInstance(Stringid,ConfigMapproperties){
SpringFactoryInstanceinstance=newSpringFactoryInstance(this,id,
properties);
instance.setSource(properties.getPropertyAsString(SOURCE,instance
.getId()));
returninstance;
}//endmethodcreateFactoryInstance()

publicObjectlookup(FactoryInstanceinst){
SpringFactoryInstancefactoryInstance=(SpringFactoryInstance)inst;
returnfactoryInstance.lookup();
}

staticclassSpringFactoryInstanceextendsFactoryInstance{
SpringFactoryInstance(SpringFactoryfactory,Stringid,
ConfigMapproperties){
super(factory,id,properties);
}

publicStringtoString(){
return"SpringFactoryinstanceforid="+getId()+"source="
+getSource()+"scope="+getScope();
}

publicObjectlookup(){
ApplicationContextappContext=WebApplicationContextUtils.getWebApplicationContext(flex.messaging.FlexContext.getServletConfig().getServletContext());
StringbeanName=getSource();

try{
returnappContext.getBean(beanName);
}catch(NoSuchBeanDefinitionExceptionnexc){
ServiceExceptione=newServiceException();
Stringmsg="Springservicenamed'"+beanName
+"'doesnotexist.";
e.setMessage(msg);
e.setRootCause(nexc);
e.setDetails(msg);
e.setCode("Server.Processing");
throwe;
}catch(BeansExceptionbexc){
ServiceExceptione=newServiceException();
Stringmsg="UnabletocreateSpringservicenamed'"
+beanName+"'";
e.setMessage(msg);
e.setRootCause(bexc);
e.setDetails(msg);
e.setCode("Server.Processing");
throwe;
}
}

}

}

4：修改remoting-config.xml

<destinationid="mytest">
<properties>
<factory>spring</factory>
<source>hello</source>
</properties>
</destination>

5：修改相应的Java类

packagecom.hongbo;

importcom.hongbo.test.TestSpring;

publicclassHello{

privateTestSpringtestSpring;

publicvoidsetTestSpring(TestSpringtestSpring){
this.testSpring=testSpring;
}

publicStringsayHello(Stringname){
returntestSpring.testSpring(name);
}
}

packagecom.hongbo.test;

publicinterfaceTestSpring{

StringtestSpring(Stringname);
}

packagecom.hongbo.test.impl;

importcom.hongbo.test.TestSpring;

publicclassTestSpringImplimplementsTestSpring{

publicStringtestSpring(Stringname){
System.out.println("testspring-------------------------------------"+name);
return"testspring"+name;
}
}

最后，flex打印语句trace不会打印到控制台，要先卸载flashplayer再安装一个debuger版的flashplayer，下载flashplayer_uninstall.zip，卸载，下载flashplayer10r12_36_winax_debug.exe，安装，卸载安装后好像谷歌浏览器没影响，然后eclipse修改默认浏览器为IE，window>preferences>General>Webbrowser，选择InternetExplorer，最后还有，启动tomcat后，必须在mxml上面右键debug运行，打开的IE才会打印trace，直接访问网址是不行的。
如有遗漏请指出
