Flex4+Spring3+Hibernate3+BlazeDS整合笔记

普通Java Web工程流行使用ssh框架，而当前台使用Flex制作的时候，后台就不需要用Struts了，通过使用BlazeDS远程方法调用即可。

首先，新建Java Web工程，然后添加Flex项目，详情见通过J2EE Web工程添加Flex项目，进行BlazeDS开发?。

随后，导入Jar包，flex相关的jar包在添加Flex项目的时候已经导入，这里主要是导入Spring和Hibernate相关的jar包以及spring和flex集成的jar包，我用的是spring 3.0.3和hibernate 3.2.1。 下面是lib列表：

???? antlr-2.7.6.jar

?? ?asm-2.2.3.jar

?修改配置文件，web.xml，其中最重要的是修改原先MessegeBroker?Servlet，改为由Spring web应用前端控制器处理所有请求。

代码

???? <!-- ?MessageBroker?Servlet?单独为Flex配置xml -->??
???? < servlet >??
???????? servlet-name >flex </ servlet-class >??
????????????org.springframework.web.servlet.DispatcherServlet??
???????? init-param >??
???????????? param-name >contextConfigLocation param-value >??
????????????????/WEB-INF/config/flex-application-config.xml??
???????????? load-on-startup >1 >??
???? >??
??
???? ?
????Map?all?/messagbroker?requests?to?the?DispatcherServlet?for?handling?
???? servlet-mapping url-pattern >/messagebroker/* >

?

?

配置?flex-application-config.xml，注意增加的几个命名空间，需要包org.springframework.flex-1.0.3.RELEASE.jar，同时在这个文件里定义了bean，在mxml里面会引用到：

flex-application-config.xml

<? xml?version="1.0"?encoding="UTF-8" ?>
beans? xmlns ="http://www.springframework.org/schema/beans" ??
????xmlns:flex ="http://www.springframework.org/schema/flex" ??
????xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance" ??
????xsi:schemaLocation ="???
????????http://www.springframework.org/schema/beans???
????????http://www.springframework.org/schema/beans/spring-beans-2.5.xsd???
????????http://www.springframework.org/schema/flex???
????????http://www.springframework.org/schema/flex/spring-flex-1.0.xsd" >

???? ?Bootstraps?and?exposes?the?BlazeDS?MessageBroker?simplest?form? -->?
???? flex:message-broker />??
????
???? bean? id ="test" ?class ="sample.Test" >
?????????? property? name ="userDAO" >
???????????? ref? bean ="userDAO" ? />

hibernate的配置，用到c0p0.jar，

?

daoContext.xml

beans
????
????xmlns:xsi
????xmlns:p ="http://www.springframework.org/schema/p"
????xsi:schemaLocation ="http://www.springframework.org/schema/beans?http://www.springframework.org/schema/beans/spring-beans-2.5.xsd" >
????
???? ?使用c3p0定义数据源Bean? -->

?test.mxml，这里主要是定义和调用远程对象，远程对象的bean在上面的flex-application-config.xml里面有定义，调用类sample.Test.java中的createUser方法。

?<?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.rpc.events.FaultEvent;
????????????import?mx.rpc.events.ResultEvent;
????????????protected?function?button_clickHandler(event:MouseEvent):void
????????????{
????????????????//?TODO?Auto-generated?method?stub
????????????????test.createUser("name","pass");
????????????}
????????????
????????????protected?function?resulth(event:ResultEvent):void
????????????{
????????????????label.text="Succeed!";
????????????}
????????????
????????????protected?function?faulth(event:FaultEvent):void
????????????{
????????????????label.text="failed!";
????????????}
???????? ]]>
???? </ fx:Declarations <!-- ?将非可视元素（例如服务、值对象）放在此处? -->
???????? mx:RemoteObject? id ="ro" ?destination ="test" ?result ="resulth(event);" ?fault ="faulth(event);" ? />
???? >
???? s:Button? x ="165" ?y ="96" ?label ="点一下" ?width ="414" ?height ="110" ?fontSize ="26" ?id ="button" ?click ="button_clickHandler(event)" s:Label? ="287" ="290" ?text ="远程调用测试" ="202" ="50" ?verticalAlign ="middle" ?textAlign ="center" ="22" ="label" />

?总结：这篇笔记不大全，只是大概展现了整合这些框架的要点，其中，主要是Flex4，spring3和BlazeDS4之间的整合。尤其需要注意的是jar包的导入。
