Flex+Spring配置

Flex+Spring配置

关键字: flex spring

    flex拓扑图制作只是一个简单的例子，可以运行，只是简单的呈现部分，如果要实现具体的拓扑图的功能，需要连接数据库，这里只简单说说flex与spring的结合，有了spring，再与hibernate以及struts就简单多了。
     1、首先是web.xml需要添加flex的配置，增加如下的内容：
     

        class>flex.messaging.HttpFlexSessionclass>




        MessageBrokerServlet
        MessageBrokerServlet
        class>flex.messaging.MessageBrokerServletclass>

            services.configuration.file
            /WEB-INF/flex/services-config.xml


            flex.write.path
            /WEB-INF/flex

        1



        FlexMxmlServlet
        MXML Processor
        Servlet wrapper for the Mxml Compiler
        class>flex.bootstrap.BootstrapServletclass>

            servlet.class
            flex.webtier.server.j2ee.MxmlServlet


            webtier.configuration.file
            /WEB-INF/flex/flex-webtier-config.xml

       1



        FlexSwfServlet
        SWF Retriever
        class>flex.bootstrap.BootstrapServletclass>

            servlet.class
            flex.webtier.server.j2ee.SwfServlet


        2



        FlexForbiddenServlet
        Prevents access to *.as/*.swc files
        class>flex.bootstrap.BootstrapServletclass>

            servlet.class
            flex.webtier.server.j2ee.ForbiddenServlet




        FlexInternalServlet
        class>flex.bootstrap.BootstrapServletclass>

            servlet.class
            flex.webtier.server.j2ee.filemanager.FileManagerServlet

        10



        MessageBrokerServlet
        /messagebroker/*



        FlexMxmlServlet
        *.mxml



        FlexSwfServlet
        *.swf



        FlexForbiddenServlet
        *.as



        FlexForbiddenServlet
        *.swc



        FlexInternalServlet
        /flex-internal/*

        flex.messaging.HttpFlexSession
     
    
    
    
        MessageBrokerServlet
        MessageBrokerServlet
        flex.messaging.MessageBrokerServlet
        
            services.configuration.file
            /WEB-INF/flex/services-config.xml
       
        
            flex.write.path
            /WEB-INF/flex
        
        1
    

    
        FlexMxmlServlet
        MXML Processor
        Servlet wrapper for the Mxml Compiler
        flex.bootstrap.BootstrapServlet
        
            servlet.class
            flex.webtier.server.j2ee.MxmlServlet
        
        
            webtier.configuration.file
            /WEB-INF/flex/flex-webtier-config.xml
        
       1
    

    
        FlexSwfServlet
        SWF Retriever
        flex.bootstrap.BootstrapServlet
        
            servlet.class
            flex.webtier.server.j2ee.SwfServlet
        
        
        2
    

    
        FlexForbiddenServlet
        Prevents access to *.as/*.swc files
        flex.bootstrap.BootstrapServlet
        
            servlet.class
            flex.webtier.server.j2ee.ForbiddenServlet
        
    

    
        FlexInternalServlet
        flex.bootstrap.BootstrapServlet
        
            servlet.class
            flex.webtier.server.j2ee.filemanager.FileManagerServlet
        
        10
    

    
        MessageBrokerServlet
        /messagebroker/*
    

    
        FlexMxmlServlet
        *.mxml
    

    
        FlexSwfServlet
        *.swf
    

    
        FlexForbiddenServlet
        *.as
    

    
        FlexForbiddenServlet
        *.swc
    

    
        FlexInternalServlet
        /flex-internal/*
    
    

    2、在spring的配置文件中增加：
   

"topoMapViewService" parent="baseTransaction">
            "target">

                            class="com.jeffrey.nms.service.impl.TopoServiceImpl">
                            "topoMapDao" ref="topoMapDao" />
                            "linkInfoDao" ref="linkInfoDao" />

    3、然后需要配置flex的配置文件，flex文件下有个services-config.xml，
增加：
   

  "spring" class="com.jeffrey.nms.web.topo.SpringFactory"/>

    其中类如下（通过网上查的）
    

    package com.jeffrey.nms.web.topo;

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;
            }
        }

    }

}

    package com.jeffrey.nms.web.topo;

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;
            } 
        }
        
    } 

} 
    

    4、本人做flex时是使用的直接调用java的运程类，以下都是按照这个配置的，还有一个webservice的方法，各位可以收集收集。
     在flex文件夹下有个remoting-config.xml文件，需要增加：
    

 "topoMap">

    spring
    topoMapViewService

lt;/destination>

     
    
        spring
        topoMapViewService
    
   
    

     这样topoMap可以在flex进行定义了，如下：
  
   这样flex+spring配置即完成。
