flex遠隔オブジェクト呼び出し、flexとspringの統合、改ページ

ここで4つの例を説明します.
1、flexの遠隔呼び出し方式(javaのBlazeck方式)を使って、一つの検索テーブルの
2,flexとspringの結合を使って、遠隔の対象を採用してテーブルの検索をします.
3,flexとspringの結合を使って、改ページクエリのリモートオブジェクト呼び出しをします.
4,flexとspringの結合を使って、改ページクエリのリモートオブジェクト呼び出しをして、表ヘッドの方式に対して
まずweb.xmlファイルを配置し、webプロジェクトを行いながら、spring容器とflexのservletを起動することができます.

<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>

flex serviceで使用するオブジェクトを追加します.spring容器で作成したオブジェクトを使用できます.
flexプロファイルservices-config.xmlに追加します.

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

このクラスのソースコードは以下の通りです.

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;
	   }
	  }
	}
}

スプリング容器の配置ファイル

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

ここでflexのリモートオブジェクトから呼び出したプロファイルを再設定します.
remoting-config.xml
最初の配置はflexが自分の配置の実用化クラスを使うことです.
第二はスプリングと結合して、スプリング容器を使って作成した実例類のオブジェクトです.

	<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方式の実用化のクラス

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;
	}

}
