用到Jeff Vroom同学写得一个SpringFactory 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; } } } } services-config.xml加上SpringFactory <factories> <factory id="spring" class="cn.aronlulu.device.service.SpringFactory" /></factories> remoting-config.xml中回调类的写法 <destination id="deviceService"> <properties> <factory>spring</factory> <source>deviceService</source > //调用类必须在spring中配置 </properties> </destination> 这样flex回调java时会从springFactory中加载类的实例,实现了blazeds与spring简单整合
