用myEclipse8.5 + flex4 + Spring BlazeDS Integration + Blaze + Gilead整合过程

 以下是框架整合顺序（前提条件是，myEclipse8.5与Flash Bulider4整合在一起）；

1、先建立一个普通web工程

2、右键webroot，选择import -> general ->file system，选中BlazeDS文件夹，会自动把BlazeDS的配置文件自动加入web工程

3、添加flex项目类型，修改flex的src路径和flex服务器路径

4、配置流行的S2SH框架（在web.xml配置struts2的action时候要这样<url-pattern>*.action</url-pattern>，否则日后flex不能与java、通信）

5、配置 Spring BlazeDS Integration 和 Gilead

特别说明一下在使用gilead框架时候用到以下2个类的作用；

这2个类是必须的，不用改是官方的！！

类名：SpringApplicationContext  

import org.springframework.context.ApplicationContext;import org.springframework.web.context.support.WebApplicationContextUtils;public class SpringApplicationContext {private static SpringApplicationContext instance = null;private SpringApplicationContext() {super();}public static SpringApplicationContext getInstance() {if (instance == null) {return new SpringApplicationContext();} else {return instance;}}public Object getSessionFactory() {ApplicationContext appContext = WebApplicationContextUtils.getWebApplicationContext(flex.messaging.FlexContext.getServletConfig().getServletContext());return appContext.getBean("sessionFactory");}}

作用：这个类是用于适配的，取得sessionFactory

类名：SpringFactory 

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.FlexFactory;import flex.messaging.config.ConfigMap;import flex.messaging.services.ServiceException;public class SpringFactory implements FlexFactory {private static final String SOURCE = "source";public void initialize(String id, ConfigMap configMap) {}public FactoryInstance createFactoryInstance(String id, ConfigMap properties) {SpringFactoryInstance instance = new SpringFactoryInstance(this, id,properties);instance.setSource(properties.getPropertyAsString(SOURCE, instance.getId()));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, id, properties);}public String toString() {return "SpringFactory instance for id=" + getId() + " source="+ getSource() + " scope=" + getScope();}public Object lookup() {ApplicationContext appContext = WebApplicationContextUtils.getWebApplicationContext(flex.messaging.FlexContext.getServletConfig().getServletContext());String beanName = getSource();try {return appContext.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;}}}}

作用：用来返回实际的Spring管理的bean 

 

在flex中的类与java端的类进行绑定的方法；

package vo{import mx.collections.ArrayCollection;import net.sf.gilead.pojo.actionscript.LightEntity;/**再现Java端的User类， * 否则Hibernate无法存储信息 * *.as类必须和 *.java类 完全一样，字段个数，字段类型 * 否则出错 */[Bindable][RemoteClass(alias="com.oa.beans.User")]public class UserVO extends LightEntity{/**id*/public var id:int;/**用户名*/public var username:String;/**密码*/public var password:String;

建一个和Java类完全一样的 as类，as类要继承LightEntity

然后加上

[RemoteClass(alias="com.oa.beans.User")]
也就是为该类对应一个Java为别名
