         <property name="dataSource" ref="dataSource"/>
     </bean>
     <bean id="dataSource" .../>


 사용 예# 2 : glue-core에 포함된 query file을 로딩해서 사용할 경우.

     <bean id="serviceLoader" class="com.poscoict.glueframework.biz.control.GlueServiceDBLoader">
         <property name="dataSource" ref="dataSource"/>
         <property name="queryManager" ref="queryManager"/>
     </bean>
     <bean id="dataSource" .../>
     <bean id="queryManager" class="com.poscoict.glueframework.dao.manager.GlueQueryManagerImpl">
         <property name="cacheManager" ref="cacheManager" />
         <property name="queryLoader" ref="queryLoader" />
     </bean>
     <bean id="cacheManager" .../>
     <bean id="queryLoader" class="com.poscoict.glueframework.dao.manager.GlueQueryLoader">
         <property name="extraQueryFiles">
             <list>
                 <value>com/poscoict/glueframework/biz/control/GlueServiceDBLoader-query.glue_sql</value>
             </list>
         </property>
     </bean>


 사용 예#3 : Table를 Customizing 한 경우, query file을 추가해서 사용하는 경우.

     <bean id="serviceLoader" class="com.poscoict.glueframework.biz.control.GlueServiceDBLoader">
         <property name="dataSource" ref="dataSource"/>
         <property name="queryManager" ref="queryManager"/>
         <property name="queryIdMap">
             <map>
                 <entry key="serviceList" value="meta.service.list.select" />
                 <entry key="serviceInfo" value="meta.service.select" />

                 <entry key="activityList" value="meta.activity.select" />
                 <entry key="transitionInfo" value="meta.transition.select" />
                 <entry key="propertyInfo" value="meta.property.select" />
             </map>
         </property>
     </bean>
     <bean id="dataSource" .../>
     <bean id="queryManager" class="com.poscoict.glueframework.dao.manager.GlueQueryManagerImpl">
         <property name="cacheManager" ref="cacheManager" />
         <property name="queryLoader" ref="queryLoader" />
     </bean>
     <bean id="cacheManager" .../>
     <bean id="queryLoader" class="com.poscoict.glueframework.dao.manager.GlueQueryLoader">
         <property name="extraQueryFiles">
             <list>
                 <value>query_user/serviceLoader-query.glue_sql</value>
             </list>
         </property>
     </bean>



 참고 : serviceLoader-query.glue_sql
