Flex4+Spring3+Hibernate3+BlazeDS整合笔记

转自http://www.cnblogs.com/noam/archive/2010/07/30/1788988.html

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：

 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。

<!-- 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>

 

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：

<?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>

hibernate的配置，用到c0p0.jar，

<?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 name="dataSource" ref="dataSource"></property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect"> org.hibernate.dialect.MySQLDialect </prop> <prop key="hibernate.show_sql"> true </prop> <prop key="hibernate.format_sql"> true </prop> <prop key="hibernate.show_statistics"> false </prop> </props> </property> <property name="mappingResources"> <list> <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>

 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:Script> <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);" /> </fx:Declarations> <s:Button x="165" y="96" label="点一下" width="414" height="110" fontSize="26" id="button" click="button_clickHandler(event)"/> <s:Label x="287" y="290" text="远程调用测试" width="202" height="50" verticalAlign="middle" textAlign="center" fontSize="22" id="label"/></s:Application>
