2、remoting-config配置
 <destination id="infoArticleService">
        <properties>
           <factory>springFactory</factory>
           <source>infoArticleService</source>
        </properties>
    </destination>

3、services-config配置
  <factories>
          <factory id="springFactory" class="cn.com.dosoft.tax.factory.SpringFactory" />
        </factories>
