SSH与Flex整合

这是我从几个文档综合而来，虽是亲手写的，却是整理而已，故不算原创，如有错不足之处，请勿喷！

Flex和Spring的整合：

1、先把spring支持的包拷贝到lib下。

2、web.xml注册spring。注册代码如下：

<!-- Spring configuration file (Not needed if you don't use Spring) -->

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>/WEB-INF/applicationContext.xml</param-value>

</context-param>

<!-- Spring ContextLoaderListener(Not needed if you don't use Spring) -->

<listener>

<listener-class>

org.springframework.web.context.ContextLoaderListener

</listener-class>

</listener>

3、增加SpringFactory.java。代码如下：

package com.samples.factories;

?

import org.springframework.context.ApplicationContext;

import org.springframework.web.context.support.WebApplicationContextUtils;

import org.springframework.beans.BeansException;

import org.springframework.beans.factory.NoSuchBeanDefinitionException;

?

import flex.messaging.FactoryInstance;

import flex.messaging.FlexFactory;

import flex.messaging.services.ServiceException;

?

public class SpringFactory implements FlexFactory{

??? private static final String SOURCE = "source";

????????? public FactoryInstance createFactoryInstance(String id,ConfigMap properties){

??????? SpringFactoryInstance instance = new SpringFactoryInstance(this,id,properties);

??????? instance.setSource(properties.getPropertyAsString(SOURCE,instance.getId()));

??????? System.out.println("SpringSpringSpring" + instance.toString());

??????? return instance;

??? }

??? public Object lookup(FactoryInstance inst){

??????? SpringFactoryInstance factoryInstance = (SpringFactoryInstance)inst;

??????? return factoryInstance.lookup();

??? }

??? static class SpringFactoryInstance extends FactoryInstance{

??????? SpringFactoryInstance(SpringFactory factory,String id,ConfigMap properties){

??????????? super(factory,properties);

??????? }

??????? public String toString(){

???????????? return "SpringFactory instance for id=" + getId() + " source=" + getSource()

????????????????????????????????????????????????????????????????????????? + " scope=" + getScope();

??????? }

??????? public Object lookup(){

??????????? ApplicationContext ac = WebApplicationContextUtils.getWebApplicationContext(flex

?????????????????????????????????????? .messaging.FlexContext.getServletConfig().getServletContext());

??????????? String beanName = getSource();

??????????? try{

??????????????? return ac.getBean(beanName);

??????????? }catch(NoSuchBeanDefinitionException nexc){

???????????????? ServiceException e = new ServiceException();

???????????????? String msg = "Spring service named '" + beanName + "' does not exist.";

???????????????? e.setMessage(msg);

???????????????? e.setRootCause(nexc);

???????????????? e.setDetails(msg);

???????????????? e.setCode("Server.Processing");

???????????????? throw e;

??????????? }catch(BeansException bexc){

?????????????????????????????????????????????????? ServiceException e = new ServiceException();

???????????????? String msg = "Unable to create Spring service named '" + beanName + "'.";

???????????????? e.setMessage(msg);

???????????????? e.setRootCause(bexc);

???????????????? e.setDetails(msg);

???????????????? e.setCode("Server.Processing");

???????????????? throw e;

??????????? }

??????? }

??? }

}

?

4、在service-config.xml中注册SpringFactory，配置如下：

<factories>

<factory id="spring" class="com.samples.factories.SpringFactory"/>

</factories>

至此，Spring配置完成。如果Tomcat日志不报错，说明spring添加成功。

?

【配置数据源】

在applicationContext.xml中增加datasource的配置，如下：

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">

??? <property name="driverClassName" value="com.mysql.jdbc.Driver"/>

??? <property name="url" value="jdbc:mysql://...?useUnicode=true&amp;characterEncoding="UTF-8"/>

??? <property name="username" value="root">

??? <property name="password" value="sa">

<bean>

5、增加业务层代码：

【Bean】

package pojo;

?

public class Userinfor{

??? private int id;

??? private String name;

??? private String pwd;

???

??? setter and getter method

}

【Dao】

package dao;

?

import java.util.Collection;

import org.springframework.dao.DataAccessException;

public interface UserDao{

??? public Collection findAll() throws DataAccessException;

}

【Impl】

package dao.impl;

?

import java.util.Collection;

import java.util.List;

?

import org.springframework.dao.DataAccessException;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

?

import dao.UserDao;

?

public class UserDaoImpl extends HibernateDaoSupport implements UserDao{

??? public Collection findAll() throws DataAccessException{

??????? List list = this.getHibernateTemplate().find("from Userinfor as a");

??????? return list;

??? }

}

?

6、在applicationContext.xml中配置bean，配置如下：

<bean id="UserDaoBean" class="dao.impl.UserDaoImpl">

??? <property name="sessionFactory" ref="sessionFactory"/>

</bean>

?

7、在remoting-config.xml中配置向Flex客户端公开的bean，配置如下：

<destination id="userService">

??? <properties>

??????? <factory>spring</factory>

??????? <source>UserDaoBean</source>

??? </properties>

</destination>

?

8、配置Flex客户端的代码：

<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">

??? <mx:Script>

??????? <![CDATA[

??????????? import mx.rpc.events.ResultEvent;

??????????? import mx.controls.Alert;

??????????? import mx.rpc.events.FaultEvnet;

??????????? private function findAllFaultHandler(event:FaultEvent):void{

??????????????? Alert.show(event.fault.faultString,"Error");

??????????? }

??????? ]]>

??? </mx:Script>

??? <mx:RemoteObject id="srv" destination="userService">

??????? <mx:method name="findAll" fault="findAllFaultHandler(event)"/>

??? </mx:RemoteObject>

??? <mx:HDividedBox width="100%" height="100%">

??? <mx:Panel title="Inventory Management" width="100%" height="100%">

??? <mx:DataGrid id="list" width="100%" height="100%" dataProvider="{srv.findAll.lastResult}">

??? <mx:columns>

??? <mx:DataGridColumn dataField="name" headerText="Name"/>

??? <mx:DataGridColumn dataField="pwd" headerText="password">

??? </mx:columns>

??? </mx:DataGrid>
??? </mx:Panel>

??? </mx:HDividedBox>

</mx:Application>

?

9、最后需要注意的地方：

右击项目-->properties-->Flex Compiler -->查看Additional compiler arguments：是否是项目在Tomcat目录下的工程的位置。
