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





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

<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

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

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



  编写SpringFactory.java




Java代码
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;     
        }      
    }    

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;  
        }   
    }
