Flex 与spring的结合
与spring的结合
?? 首先下载springFactory.java,内容如下：
????
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;
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;
??? } // end method createFactoryInstance()
??????? 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;
??????????? }
??????? }
???????
??? }
}
接着在services-config.xml里加入：
??? <factories>
????? <factory id="spring" class="包名.SpringFactory"/>
?</factories>
?我们在applicationContext.xml里配置bean
??? <bean id="testFactory"? class="HelloWorld"/>
?在remoting-config.xml里加入：
???? <destination id="testFac">
??????? <properties>
???????? <factory>spring</factory>
????????? <source>testFactory</source>
??????? </properties>
??? </destination>
后台已经配置完毕，在前台：
??? <mx:RemoteObject?? id = "ro"??? endpoint="/TestFlex/messagebroker/amf"? destination="testFac"? result = "resultHandler(event)"/>
可以看出remoting-config.xml里配置起到了中转的作用???
