为SSH架构的java web项目添加flex支持

 

     java+flex开发环境在此不再介绍，SSH架构的java项目的搭建也不再多说（示例项目采用tomcat作为服务器，端口为9080）。

    首先，解压blazeds.war,将得到的messageing-config.xml,proxy-config.xml,remoting-config.xml,services-config.xml四个文件复制到WEB-INF下的flex文件夹下，将以下jar包复制到项目中

，web.xml中添加以下代码

<servlet>
<display-name>MessageBrokerServlet</display-name>
<servlet-name>MessageBrokerServlet</servlet-name>
<servlet-class>flex.messaging.MessageBrokerServlet</servlet-class>
<init-param>
<param-name>services.configuration.file</param-name>
<param-value>/WEB-INF/flex/services-config.xml</param-value>
</init-param>
<load-on-startup>11</load-on-startup>
</servlet>

 

 

右击项目，选择添加/更变项目类型------添加flex项目类型，如下图：<!--StartFragment --> 

 



 选择j2ee服务器，



，至此，项目添加flex支持完成，在此分享两个工具类，

package com.iman.common;

import  org.springframework.beans.BeansException;
import  org.springframework.beans.factory.NoSuchBeanDefinitionException;
import  org.springframework.context.ApplicationContext;
import  org.springframework.web.context.support.WebApplicationContextUtils;

import  flex.messaging.FactoryInstance;
import  flex.messaging.config.ConfigMap;
import  flex.messaging.services.ServiceException;

public class SpringFactoryInstance  extends  FactoryInstance
{
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;
}
}

}

 

package com.iman.common;

import flex.messaging.FactoryInstance;
import flex.messaging.FlexFactory;
import flex.messaging.config.ConfigMap;

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) {

}

}

 remoting-config.xml中配置远程对象，需要从springfactory中获取的可以采取以下配置

<destination id="topDisplayDataManager">
<properties>
<factory>springFactory</factory>
<source>topDisplayDataManager</source>
</properties>
</destination>

 

当然，这个bean你必须事先在spring配置文件中配置。
