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.。 下面是lib列表：

     antlr-2.7..jar

    asm-2.2..jar

    asm-commons-2.2..jar

    asm-util-2.2..jar

    aspectjlib.jar

    ehcache-1.2..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..jar

    hibernate-commons-annotations-3.2..Final.jar

    hibernate-core-3.5.-Final.jar

    hibernate-jpa-2.0-api-1.0..Final.jar

    jackson-lgpl-0.9..jar

    javassist.jar

    jta-1.1.jar

    log4j-1.2..jar

    mysql-connector-java-5.1.-bin.jar

    org.springframework.aop-3.0..RELEASE.jar

    org.springframework.asm-3.0..RELEASE.jar

    org.springframework.aspects-3.0..RELEASE.jar

    org.springframework.beans-3.0..RELEASE.jar

    org.springframework.instrument.tomcat-3.0..RELEASE.jar

    org.springframework.jdbc-3.0..RELEASE.jar

    org.springframework.jms-3.0..RELEASE.jar

    org.springframework.orm-3.0..RELEASE.jar

    org.springframework.oxm-3.0..RELEASE.jar

    org.springframework.test-3.0..RELEASE.jar

    org.springframework.transaction-3.0..RELEASE.jar

    org.springframework.web.portlet-3.0..RELEASE.jar

    org.springframework.web.servlet-3.0..RELEASE.jar

    org.springframework.web.struts-3.0..RELEASE.jar

    slf4j-api-1.5..jar

    slf4j-log4j12-1.5..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></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 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>

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>

        <!-- 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>

 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
