Flex、Spring调整:blazeds
Flex、Spring整合:blazeds
准备:
1、下载blazeds 4.x,下载地址:http://download.macromedia.com/pub/livecycle/blazeds/4_0/blazeds-bin-4.0.0.14931.zip
2、部署blazeds至tomcat,访问http://localhost:8080/blazeds/messagebroker/amf,显示空白页,则部署成功
整合:
====================服务端开发========================================
1、建立一测试Service:
2、配置bean:在blazeds/WEB-INF/下新建applicationContext.xml文件,添加
3、修改web.xml文件,添加spring支持
4、打开blazeds/WEB-INF/flex/services-config.xml,添加
使得flex的bean对象创建交由spring负责
SpringFactory类的代码如下:
5、将service公开,提供flex客户端调用:打开blazeds/WEB-INF/flex/remoting-config.xml,增加如下配置
至此,服务端整合、开发完毕
====================客户端开发========================================
1、新建flex应用程序,添加remoteObject调用:
注意这边的guestListService整合就是与remoting-config.xml中配置的destination的id保持一致
至此客户端就得到了服务器端的数据了,下面就是根据业务*处理了。
效果图:

====================服务端开发========================================
1、建立一测试Service:
public class GuestListService implements Serializable, IGuestListService { private static final long serialVersionUID = 3552207441192189726L; public List<Guest> getGuestList() { List<Guest> guestList = new ArrayList<Guest>(); guestList.add(new Guest("Guest One")); guestList.add(new Guest("Guest Two")); guestList.add(new Guest("Guest Three")); guestList.add(new Guest("Guest Four")); return guestList; } }
2、配置bean:在blazeds/WEB-INF/下新建applicationContext.xml文件,添加
<beans> <bean id="guestListService" class="com.sky.flexonspring.services.GuestListService" /> </beans>
3、修改web.xml文件,添加spring支持
<context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext.xml</param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener>
4、打开blazeds/WEB-INF/flex/services-config.xml,添加
<factories> <factory id="spring" class="com.sky.flexonspring.factories.SpringFactory" /> </factories>
使得flex的bean对象创建交由spring负责
SpringFactory类的代码如下:
package com.sky.flexonspring.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.config.ConfigMap; import flex.messaging.services.ServiceException; /** * This interface is implemented by factory components which provide instances * to the flex messaging framework. * * @author Jeff Vroom */ public class SpringFactory implements FlexFactory { private static final String SOURCE = "source"; /** * This method can be used to initialize the factory itself. It is called * with configuration parameters from the factory tag which defines the id * of the factory. */ public void initialize(String id, ConfigMap configMap) { } /** * This method is called when we initialize the definition of an instance * which will be looked up by this factory. It should validate that the * properties supplied are valid to define an instance. Any valid properties * used for this configuration must be accessed to avoid warnings about * unused configuration elements. If your factory is only used for * application scoped components, this method can simply return a factory * instance which delegates the creation of the component to the * FactoryInstance's lookup method. */ public FactoryInstance createFactoryInstance(String id, ConfigMap properties) { SpringFactoryInstance instance = new SpringFactoryInstance(this, id, properties); instance.setSource(properties.getPropertyAsString(SOURCE, instance.getId())); return instance; } // end method createFactoryInstance() /** * Returns the instance specified by the source and properties arguments. * For the factory, this may mean constructing a new instance, optionally * registering it in some other name space such as the session or JNDI, and * then returning it or it may mean creating a new instance and returning * it. This method is called for each request to operate on the given item * by the system so it should be relatively efficient. * <p> * If your factory does not support the scope property, it report an error * if scope is supplied in the properties for this 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; } } } }
5、将service公开,提供flex客户端调用:打开blazeds/WEB-INF/flex/remoting-config.xml,增加如下配置
<destination id="guestListService"> <properties> <factory>spring</factory> <source>guestListService</source> </properties> </destination>
至此,服务端整合、开发完毕
====================客户端开发========================================
1、新建flex应用程序,添加remoteObject调用:
<mx:RemoteObject id="ro" destination="guestListService" endpoint="http://localhost:8080/blazeds/messagebroker/amf" result="resultHandler(event)" fault="faultHandler(event)"/>
注意这边的guestListService整合就是与remoting-config.xml中配置的destination的id保持一致
ro.getGuestList()这段代码调用就得到调用
GuestListService.getGuestList()后的List<Guest> 列表
private function resultHandler(event:ResultEvent):void { guestListDP = ArrayCollection(event.result); }
至此客户端就得到了服务器端的数据了,下面就是根据业务*处理了。
