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 asm-commons-2.2.3.jar asm-util-2.2.3.jar aspectjlib.jar aspectjrt.jar aspectjweaver.jar backport-util-concurrent.jar c3p0-0.9.1.jar cfgatewayadapter.jar cglib-nodep-2.1_3.jar com.springsource.edu.emory.mathcs.backport-3.0.0.jar com.springsource.net.sf.cglib-2.2.0.jar com.springsource.org.aopalliance-1.0.0.jar commons-codec-1.3.jar commons-collections-3.1.jar commons-httpclient-3.0.1.jar commons-io-1.4.jar commons-lang-2.3.jar commons-logging.jar dom4j-1.6.1.jar ehcache-1.2.3.jar flex-messaging-common.jar flex-messaging-core.jar flex-messaging-opt.jar flex-messaging-proxy.jar flex-messaging-remoting.jar flex-rds-server.jar freemarker-2.3.15.jar hibernate-commons-annotations-3.2.0.Final.jar hibernate-core-3.5.4-Final.jar hibernate-jpa-2.0-api-1.0.0.Final.jar jackson-lgpl-0.9.5.jar javassist.jar jta-1.1.jar log4j-1.2.15.jar mysql-connector-java-5.1.13-bin.jar org.springframework.aop-3.0.3.RELEASE.jar

slf4j-api-1.5.8.jar slf4j-log4j12-1.5.8.jar xalan.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。 复制代码 代码 <!-- MessageBroker Servlet 单独为Flex配置xml--> <servlet> <servlet-name>flex</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/config/flex-application-config.xml </param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!-- Map all /messagbroker requests to the DispatcherServlet for handling --> <servlet-mapping> <servlet-name>flex</servlet-name> <url-pattern>/messagebroker/*</url-pattern> </servlet-mapping> 复制代码 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： 复制代码 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" /> </property> <flex:remoting-destination /> </bean> </beans> 复制代码 hibernate的配置，用到c0p0.jar， daoContext.xml 复制代码 <?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: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 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"> <property name="driverClass" value="com.mysql.jdbc.Driver"/> <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/db"/> <property name="user" value="user"/> <property name="password" value="pass"/> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property

<value>sample/dao/User.hbm.xml</value> </list> </property> </bean> <bean id="userDAO" class="sample.dao.UserDAO"> <property name="sessionFactory"> <ref bean="sessionFactory" /> </property> </bean> </beans> 复制代码 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"?> 复制代码 <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:Script> <fx:Declarations> <!--

</s:Application> 复制代码 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。 本文没有涉及到blazeDS和spring整合实现远程方法调用服务和消息服务的配置，会在接下来写。 这里有一个个人觉得还蛮不错的Flex教程：Flex系列教程BY蒲公英
