FLEX和spring、hibernate的集成

Posted under Web相关 by admin

flex的后台使用spring+hibernate，spring+hibernate的集成方法和j2ee的项目中方法相同。主要是flex和spring的集成

编写SpringFactory.java类：

java 代码

 

package com.fire.spring;

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;
            }
        }

    }

}

配置WEB-INF/flex/service-config.xml，在最后添加如下代码：

xml 代码

xml 代码

 

<factories>
        <factory id=“spring” class=“com.fire.spring.SpringFactory”/>
    factories>

 在使用remoteobject的时候，配置remote-config.xml时，如下进行配置：

xml 代码

 

<destination id=“provinceService”>
        <properties>
            <factory>spring</factory>
            <source>provinceService</source>
        </properties>
    </destination>

不知道博主能不能看懂这个例子，反正我是看不懂
最好加工一下变成你自己的东西，
