这里讲解四个例子
1，使用flex的远程调用方式（java的BlazeDS方式）一个查询table的
2，使用flex和spring的结合，采用远程对象做一个table的查询
3，使用flex和spring的结合，做一个分页查询的远程对象调用
4，使用flex和spring的结合，做一个分页查询的远程对象调用，对表头的方式

首先配置web.xml文件，一边web工程能够启动spring容器和flex的servlet 

<context-param>
  	<param-name>contextConfigLocation</param-name>
	<param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  	<listener>
	    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
  	<!-- Http Flex Session attribute and binding listener support -->
	<listener>
		<listener-class>flex.messaging.HttpFlexSession</listener-class>
	</listener>

	<!-- MessageBroker Servlet -->
	<servlet>
		<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>
		<init-param>
			<param-name>flex.write.path</param-name>
			<param-value>/WEB-INF/flex</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>MessageBrokerServlet</servlet-name>
		<url-pattern>/messagebroker/*</url-pattern>
	</servlet-mapping>


增加一个flex service中使用的对象能够使用spring容器中创建的对象
在flex配置文件services-config.xml中增加 

<factories>
       <factory id="spring" class="com.fruitking.report.flex.util.FlexSpringFactory" />
    </factories>


这个类的源代码如下 

package com.fruitking.report.flex.util;

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

public class FlexSpringFactory 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(FlexSpringFactory 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;
	   }
	  }
	}
}


spring容器的配置文件 

<bean id="springIOCProductService" class="com.fruitking.report.service.impl.SpringProductServiceImpl">
	</bean>


这里再配置flex远程对象调用的配置文件
remoting-config.xml
第一个配置就是flex使用自己的配置实例化类
第二就是和spring结合，使用spring容器里创建的实例类对象 

	<destination id="flexProductService">
        <properties>
            <source>com.fruitking.report.service.impl.FlexProductServiceImpl</source>
        </properties>
    </destination>

    <destination id="springProductService">
    	<properties>
    		<factory>spring</factory>
    		<source>springIOCProductService</source>
    		<scope>session</scope>
    	</properties>
    </destination>


flex方式实例化的类 

public class FlexProductServiceImpl {

	public List<Product> getProductList(){
		List<Product> productList = new ArrayList<Product>();
		try{
			Product product = null;
			for(int i=0;i<10;i++){
				product = new Product();
				product.setProductId(""+i);
				product.setProductName(ContentUtil.getProductName(i));
				product.setProductArea(ContentUtil.getProductArea(i));
				product.setTotalSaleNumber(ContentUtil.getProductTotalSale(i));
				product.setTotalBackNumber(ContentUtil.getProductTotalBack(i));
				BigDecimal totalBackNumber = BigDecimal.valueOf(product.getTotalBackNumber());
				BigDecimal totalSaleNumber = BigDecimal.valueOf(product.getTotalSaleNumber());
				BigDecimal percent = totalBackNumber.divide(totalSaleNumber,4,BigDecimal.ROUND_HALF_EVEN);
				percent = percent.divide(BigDecimal.valueOf(0.01d),2,BigDecimal.ROUND_HALF_EVEN);
				product.setTotalBackPercent(percent.toString()+"%");
				productList.add(product);
			}
		}catch(Exception e){
			e.printStackTrace();
		}
		return productList;
	}

}


spring实例化的类 

public class SpringProductServiceImpl {

	private int pageSize = 10;
	private int pageTotal = 56;

	public List<Product> getProductList(){
		List<Product> productList = new ArrayList<Product>();
		Product product = null;
		for(int i=0;i<10;i++){
			product = new Product();
			product.setProductId(""+i);
			product.setProductName(ContentUtil.getProductName(i));
			product.setProductArea(ContentUtil.getProductArea(i));
			product.setTotalSaleNumber(ContentUtil.getProductTotalSale(i));
			product.setTotalBackNumber(ContentUtil.getProductTotalBack(i));
			BigDecimal totalBackNumber = BigDecimal.valueOf(product.getTotalBackNumber());
			BigDecimal totalSaleNumber = BigDecimal.valueOf(product.getTotalSaleNumber());
			BigDecimal percent = totalBackNumber.divide(totalSaleNumber,4,BigDecimal.ROUND_HALF_EVEN);
			percent = percent.divide(BigDecimal.valueOf(0.01d),2,BigDecimal.ROUND_HALF_EVEN);
			product.setTotalBackPercent(percent.toString()+"%");
			productList.add(product);
		}
		return productList;
	}

	public FlexPageObject getProductPageList(int pageNumber){
		if(pageNumber<=0){
			pageNumber = 1;
		}
		if(pageNumber>pageTotal){
			pageNumber = pageTotal;
		}
		int productCode = pageSize*(pageNumber-1);
		productCode++;
		FlexPageObject flexPageObject = new FlexPageObject();
		List<Product> productList = new ArrayList<Product>();
		Product product = null;
		for(int i=0;i<pageSize;i++){
			product = new Product();
			product.setProductId(""+productCode);
			product.setProductName(ContentUtil.getProductName(i));
			product.setProductArea(ContentUtil.getProductArea(i));
			product.setTotalSaleNumber(ContentUtil.getProductTotalSale(i));
			product.setTotalBackNumber(ContentUtil.getProductTotalBack(i));
			BigDecimal totalBackNumber = BigDecimal.valueOf(product.getTotalBackNumber());
			BigDecimal totalSaleNumber = BigDecimal.valueOf(product.getTotalSaleNumber());
			BigDecimal percent = totalBackNumber.divide(totalSaleNumber,4,BigDecimal.ROUND_HALF_EVEN);
			percent = percent.divide(BigDecimal.valueOf(0.01d),2,BigDecimal.ROUND_HALF_EVEN);
			product.setTotalBackPercent(percent.toString()+"%");
			productList.add(product);
			productCode++;
		}
		flexPageObject.setObjectList(productList);
		flexPageObject.setPageNumber(pageNumber);
		flexPageObject.setPageSize(pageSize);
		flexPageObject.setPageTotal(pageTotal);
		return flexPageObject;
	}

	public FlexPageObject getMutilProductPageList(int pageNumber){
		if(pageNumber<=0){
			pageNumber = 1;
		}
		if(pageNumber>pageTotal){
			pageNumber = pageTotal;
		}
		int productCode = pageSize*(pageNumber-1);
		productCode++;
		FlexPageObject flexPageObject = new FlexPageObject();
		List<Product> productList = new ArrayList<Product>();
		Product product = null;
		for(int i=0;i<pageSize;i++){
			product = new Product();
			product.setProductId(""+productCode);
			product.setProductName(ContentUtil.getProductName(i));
			product.setProductArea(ContentUtil.getProductArea(i));
			product.setTotalSaleNumber(ContentUtil.getProductTotalSale(i));
			product.setTotalBackNumber(ContentUtil.getProductTotalBack(i));
			BigDecimal backNumber = BigDecimal.valueOf(product.getTotalBackNumber());
			BigDecimal saleNumber = BigDecimal.valueOf(product.getTotalSaleNumber());
			BigDecimal percent = backNumber.divide(saleNumber,4,BigDecimal.ROUND_HALF_EVEN);
			percent = percent.divide(BigDecimal.valueOf(0.01d),2,BigDecimal.ROUND_HALF_EVEN);
			product.setTotalBackPercent(percent.toString()+"%");
			product.setWeekSaleNumber(ContentUtil.getProductWeekSale(i));
			product.setWeekBackNumber(ContentUtil.getProductWeekBack(i));
			backNumber = BigDecimal.valueOf(product.getWeekBackNumber());
			saleNumber = BigDecimal.valueOf(product.getWeekSaleNumber());
			percent = backNumber.divide(saleNumber,4,BigDecimal.ROUND_HALF_EVEN);
			percent = percent.divide(BigDecimal.valueOf(0.01d),2,BigDecimal.ROUND_HALF_EVEN);
			product.setWeekBackPercent(percent.toString()+"%");
			product.setYesterdaySaleNumber(ContentUtil.getProductYesterdaySale(i));
			product.setYesterdayBackNumber(ContentUtil.getProductYesterdayBack(i));
			productList.add(product);
			productCode++;
		}
		flexPageObject.setObjectList(productList);
		flexPageObject.setPageNumber(pageNumber);
		flexPageObject.setPageSize(pageSize);
		flexPageObject.setPageTotal(pageTotal);
		return flexPageObject;
	}

}

组装对象 

public class Product {

	private String productId;//产品编号
    private String productName;//产品名称
    private String productArea;//产品出差地
    private String countWeek;//统计周数
    private int totalSaleNumber;//累计总销售数
    private int totalBackNumber;//累计总退回数
    private String totalBackPercent;//总返回率
    private int weekSaleNumber;//本周销售数
    private int weekBackNumber;//本周退回数
    private String weekBackPercent;//本周返回率
    private int yesterdaySaleNumber;//昨日销售数
    private int yesterdayBackNumber;//昨日退回数
}


分页对象 


public class FlexPageObject {

	private int pageNumber;//当前页
	private int pageSize;//页大小
	private int pageTotal;//总页数
	private List<?> objectList;//分页对象集合
}

第一个flex调用的table的mxml代码 


<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
	<mx:Script>

       public function handleQueryData(event:ResultEvent):void{
       		rerultProductList = ArrayCollection(event.result);
       		productList.dataProvider = rerultProductList;
       }
