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
