FLEX和Spring、Hibernate的集成 - Flex+Spring

remoting-config.xml：
<destination id="TestSpring">
        <properties>
            <factory>spring</factory>
            <source>springTest</source> <!--此处注入IOC注入-->
        </properties>
    </destination>

==============================================================
services-config.xml：
    <factories>
      <factory id="spring" class="flex.samples.factories.SpringFactory" />
    </factories>
==============================================================
web.xml： 和struts整合spring一样
    <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>

applicationContext.xml

 

 <bean id="springTest" class="flex.samples.SpringTest">
  <property name="description">
   <value>Hello Flex To Spring</value>
  </property>
