轻松打造J2EE的 SSH 与flash builder整合(由Spring类管理)

在此将我所配置方法,,告知大家..让大家少走弯路

 

 

下面将由我来 手把手教大家 如果 配置SSH 以及将flash builder整合到一起

并由Spring类来管理,,使flash builder直接通过AMF访问java后台类方

 

 

环境:

My Eclipse 8.5

Struts 1.2

Spring 2

hibernate  3.1

flash builder 4 / 或插件版

 

 

1.前期环境

新建项目名为:  MyWeb

建包:

com.sshf.study.entity   (实体包)

com.sshf.study.dao(数据访问包)

com.sshf.study.biz(业务逻辑)

 

并在 com.sshf.study.biz 包下

新建接口 IHelloWord.java

并再建包 impl,  HellWordImpl.java 类(全速路径 com.sshf.study.biz.impl.HellWordImpl). 并实现IHelloWord接口

代码如下:

 

package com.sshf.study.biz;import com.sshf.study.biz.IHelloWord;public class HelloWordImpl implements IHelloWord{/** * 测试方法 * @param name * @return */public String sayHello(String name){return "HelloHello! " + name; }}

 

稍后我们会 测试调用这个方法!

 

 

2.开始SSH搭建.

a.首先加入Spring框架

自己加入DataSource sessionFactory 实体bean DAOBean 以及事务..养成好习惯

以下是我的初期配置(稍后会添加):

 

<?xml version="1.0" encoding="UTF-8"?><!-- 导入命名空间--><beans xmlns="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/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd"> <!-- 配置事务管理 --> <bean id="myHibTxManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <!--配置事务管理策略--> <tx:advice id="txAdvice" transaction-manager="myHibTxManager"> <tx:attributes> <tx:method name="to*" propagation="SUPPORTS" read-only="true" /> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="find*" propagation="REQUIRED" /> </tx:attributes> </tx:advice> <aop:config> <!--指定用于那些地方--> <aop:pointcut id="bizMethods" expression="execution(* com.sshf.study.*.impl.*.*(..))" /> <!-- 织入 --> <aop:advisor advice-ref="txAdvice" pointcut-ref="bizMethods" /> </aop:config> <!-- dataSource --> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver"> </property> <property name="url" value="jdbc:sqlserver://localhost:1433"></property> <property name="username" value="sa"></property> <property name="password" value="dongqiao"></property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource"> <ref bean="dataSource" /> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect"> org.hibernate.dialect.SQLServerDialect </prop> </props> </property> <property name="mappingResources"> <list> <value>entity/ConfigQuestionSecondKind.hbm.xml</value> <value>entity/EngageSubjects.hbm.xml</value> <value>entity/ConfigQuestionFirstKind.hbm.xml</value></list> </property> </bean> <!-- DAO --> <!-- biz --> <bean id="HW" class="com.sshf.study.biz.impl.HellWordImpl"> </bean> <!-- action --> </beans>

b.添加Struts支持

如用到Action 一定不要忘了改 代理类 org.springframework.web.struts.DelegatingActionProxy

c.添加hibernate支持.

 

以上二步省略.. 相信大家都会配..

 

 

3.开始将flash builder整合到SSH中

a.下载blazeDS包 将WEB-INF 文件夹下的所有文件夹和文件 拷贝到/WebRoot/WEB-INF/目录下

注意:包括web.xml 全覆盖

b.打开Web.xml 进行配置spring

<!--在web.xml中引入Spring的代码--> <context-param> <!-- 参数名为contextConfigLocation --> <param-name>contextConfigLocation</param-name> <!-- 配置多个文件之间，以","隔开 --> <param-value>/WEB-INF/classes/app.xml</param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener>

(此处app.xml为spring配置文件名 默认为applicationContext.xml)

到此为止..SSH配置完毕..部署运行一下..看是否有错误..

如有错误 自己 改正. 在确保SSH集成后无错 方可 继续.!!

 

 

以下步骤很重要

b.新建包com.sshf.study.flash

在该包下新建二个类  SpringFactoryInstance.java  FlexFactoryImpl.java

SpringFactoryInstance.java代码

package com.sshf.study.flash; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; import org.springframework.beans.BeansException; import org.springframework.beans.factory.NoSuchBeanDefinitionException; import org.springframework.context.ApplicationContext; import org.springframework.web.context.support.WebApplicationContextUtils; import flex.messaging.FactoryInstance; import flex.messaging.FlexContext; import flex.messaging.FlexFactory; import flex.messaging.config.ConfigMap; import flex.messaging.services.ServiceException; public class SpringFactoryInstance extends FactoryInstance { private Log log = LogFactory.getLog(getClass()); SpringFactoryInstance(FlexFactory factory, String id, ConfigMap properties) { super(factory, id, properties); } public Object lookup() { System.out.println("3---spring工厂类的方法lookup"); ApplicationContext appContext = WebApplicationContextUtils.getRequiredWebApplicationContext(FlexContext.getServletConfig().getServletContext()); String beanName = getSource(); try { log.info("Lookup bean from Spring ApplicationContext: " + beanName); return appContext.getBean(beanName); } catch (NoSuchBeanDefinitionException nex) { ServiceException e = new ServiceException(); String msg = "Spring service named '" + beanName + "' does not exist."; e.setMessage(msg); e.setRootCause(nex); e.setDetails(msg); e.setCode("Server.Processing"); throw e; } catch (BeansException bex) { ServiceException e = new ServiceException(); String msg = "Unable to create Spring service named '" + beanName + "'."; e.setMessage(msg); e.setRootCause(bex); e.setDetails(msg); e.setCode("Server.Processing"); throw e; } catch (Exception ex) { ServiceException e = new ServiceException(); String msg = "Unexpected exception when trying to create Spring service named '" + beanName + "'."; e.setMessage(msg); e.setRootCause(ex); e.setDetails(msg); e.setCode("Server.Processing"); throw e; } }} 

 

 FlexFactoryImpl.java代码

package com.sshf.study.flash;import org.apache.commons.logging.Log;import org.apache.commons.logging.LogFactory;import flex.messaging.FactoryInstance;import flex.messaging.FlexFactory;import flex.messaging.config.ConfigMap; public class FlexFactoryImpl implements FlexFactory { private Log log = LogFactory.getLog(getClass()); /*override interface method*/ public void initialize(String id, ConfigMap configMap) { System.out.println("1---flex工厂实现类重写的方法initialize"); } /*override interface method*/ public FactoryInstance createFactoryInstance(String id, ConfigMap properties) { System.out.println("2---flex工厂实现类重写的方法createFactoryInstance"); log.info("Create FactoryInstance."); SpringFactoryInstance instance = new SpringFactoryInstance(this, id, properties); instance.setSource(properties.getPropertyAsString(SOURCE, instance.getId())); return instance; } /*override interface method*/ public Object lookup(FactoryInstance instanceInfo) { System.out.println("4---flex工厂实现类重写的方法lookup"); log.info("Lookup service object."); return instanceInfo.lookup(); } } 

 

 

打开/WEB-INF/flex/services-config.xml 配置文件

 加入FlexFactory实现类

<factories> <factory id="flexFactoryImpl" class="com.sshf.study.flash.FlexFactoryImpl"/></factories> 

 

打开/WEB-INF/flex/remoting-config.xml 配置文件

然后将 services中的factory的实现类所调用的类配置关联 

 

<destination id="flash"> <properties> <!-- flexFactory实现类 --> <factory>flexFactoryImpl</factory> <!-- 对外的访问类 为spring配置中的bean id --> <source>HW</source> <scope>application</scope> </properties> </destination> 

 

到此为止 配置完毕

部署运行..有错误改之

 

4.新建一个flex 项目

 并新建一个mxml

不一一做介绍了..添加一个 文本框 和一个 按钮..

 

点击 按钮 将 文本框中 字符串 传入到 HelloWordImpl 的 sayHello中.并取返回值 输出

代码如下:

<?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.controls.Alert; import mx.rpc.events.FaultEvent; import mx.rpc.events.ResultEvent; protected function button1_clickHandler(event:MouseEvent):void { var remote:RemoteObject = new RemoteObject(); remote.destination = "flash";//remoting-config中destination ID //访问地址可改 在web.xml中修改 这里默认 remote.endpoint = "http://localhost:8080/myWeb/messagebroker/amf"; remote.addEventListener(ResultEvent.RESULT, myResult);//添加访问成功后回调函数 remote.addEventListener(FaultEvent.FAULT,fault);//添加访问失败后回调函数 remote.sayHello(u.text);//执行 服务器类的 sayHell方法, } private function myResult(evt:ResultEvent):void{ Alert.show(evt.result.toString()); } private function fault(evt:FaultEvent):void{ Alert.show(evt.fault.message); } ]]--> </fx:Script> <fx:Declarations> <!-- 将非可视元素（例如服务、值对象）放在此处 --> <mx:RemoteObject id="say" destination="Test"> </mx:RemoteObject> </fx:Declarations> <s:Button x="451" y="251" label="按钮" click="button1_clickHandler(event)"/> <s:TextInput x="290" y="250" id="u"/></s:Application> 

 

以上为整合内容.

 

 

 

由于本人最近较忙..故没有多少时间!!

 

有时间给大家做一些 控件 以及 其它 与java后台高级交互文章..
