SCA学习之2--SCA中使用SPRING笔记

最近在看APACHE 的TUSCANY，其中的simple-bigbank-spring的例子，就是说如何在SCA中使用SPRING的。
首先看resources目录下bigbank.compsite文件

<composite xmlns="http://www.osoa.org/xmlns/sca/1.0"
  xmlns:tuscany="http://tuscany.apache.org/xmlns/sca/1.0"
  targetNamespace="http://bigbank"
  xmlns:s="http://stockquote"
  name="BigBank">    <component name="AccountServiceComponent">
         <implementation.spring location="Account-spring-context.xml"/>
         <reference name="stockQuoteService" target="StockQuoteServiceComponent"/>
     </component>    <component name="StockQuoteServiceComponent">
         <implementation.composite name="s:StockQuote"/>
     </component></composite>

可以看到，在AccountServiceComponent这个组件中，其实现是直接用<implementation.spring location="Account-spring-context.xml"/>
指向了spring的配置文件。再看具体的这个SPRING配置文件
  

<beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:sca="http://www.springframework.org/schema/sca"
        xsi:schemaLocation="
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/sca http://www.springframework.org/schema/sca/spring-sca.xsd">    <sca:service name="AccountService"
   type="bigbank.account.AccountService" target="AccountServiceBean"/>    <bean  class="bigbank.account.AccountServiceImpl">
         <property name="accountDataService" ref="AccountDataServiceBean"/>
         <property name="stockQuoteService" ref="stockQuoteService"/>
         <property name="currency" value="USD"/>
     </bean>    <bean  class="bigbank.accountdata.AccountDataServiceImpl">
     </bean>    <sca:reference name="stockQuoteService"
   type="bigbank.stockquote.StockQuoteService"/></beans>

由于是在SCA的容器内，所以这里要引用外部的服务的话，依然要用<sca:reference>来进行。
