????? 这一讲是基于DEMO11，所以没有看DEMO11的读者请一定阅读，因为Spring的整合是基于J2EE的。
????? 因为要和Spring整合，所以先简单讲一下Spring（如果要对Spring没有接触过的读者也没关系，按照讲的内容也能做，但是这样没啥实际意义，所以要对本讲要有所收获，必须对Spring有一定的理解）。
????? 首先下载Spring，作者选择的Spring版本Spring Framework2.0.8。可以在官网

?* You also must configure the web application to use spring and must copy the spring.jar
?* file into your WEB-INF/lib directory.? To configure your app server to use spring,
?* you add the following lines to your WEB-INF/web.xml file:
?*
?*?? <context-param>
?*??????? <param-name>contextConfigLocation</param-name>
?*??????? <param-value>/WEB-INF/applicationContext.xml</param-value>
?*?? </context-param>
?*
?*?? <listener>
?*?????? <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
?*?? </listener>
?*
?* Then you put your spring bean configuration in WEB-INF/applicationContext.xml (as per the
?* line above).? For example:
?*
?*? <?xml version="1.0" encoding="UTF-8"?>
?*? <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
?*??
?*? <beans>
?*??? <bean name="weatherBean" singleton="true"/>
?*? </beans>
?*?
?* Now you are ready to define a destination in flex that maps to this existing service.
?* To do this you'd add this to your WEB-INF/flex/remoting-config.xml:
?*
?*? <destination id="WeatherService">
?*????? <properties>
?*????????? <factory>spring</factory>
?*????????? <source>weatherBean</source>
?*????? </properties>
?*? </destination>
