用Flex+Spring+Hibernate写一个登录

1下载支持文件flex-spring.zip

新建FlexLCDS工程File -> new -> Flex Project 这里不细说这个。请看http://nic.iteye.com/blog/247604

前端是flex.中间层使用spring接着hibernate，spring+hibernate的集成方法和j2ee的项目中方法相同

修改WEB-INF\web.xml ,加入下面代码

 

 

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

 

注册sping factory，

修改WEB-INF\flex配置

<factory id="springFactory" class="cn.org.coral.core.flex.factory.FlexSpringFactory" />

 

 

Class属性填写第一步中考入项目SpringFactory类的路径

3 注册bean到remoting-config.xml

<destination id="teacherDao">  
      <properties>  
              <factory>springFactory</factory>    
              <source>TeacherDAO</source>  
              
      </properties>  
</destination>

 

 

  编写SpringFactory.java

 

public class FlexSpringFactory implements FlexFactory {

	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();   
	}
	public void initialize(String arg0, ConfigMap arg1) {
	
	}

}

public class SpringFactoryInstance extends FactoryInstance   
{   
	public  SpringFactoryInstance(FlexSpringFactory factory, String id, ConfigMap properties)   
    {   
        super(factory, id, properties);   
    }   
    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();   
            throw e;   
        }   
        catch (BeansException bexc)   
        {   
            ServiceException e = new ServiceException();   
            throw e;   
        }    
    }
