Class GlueServiceDBLoader

java.lang.Object

com.poscoict.glueframework.biz.control.GlueServiceDBLoader

All Implemented Interfaces:

GlueCacheLoader, org.springframework.beans.factory.InitializingBean

public class GlueServiceDBLoader
extends Object
implements GlueCacheLoader, org.springframework.beans.factory.InitializingBean

CacheLoader 구현체. GlueServiceDBLoader는 Cache에서 해당 Service객체(GlueService)를 찾고 없으면 DB을 읽어서 Cache에 저장한다.

 예제
 사용 예# 1 : 제공된 Table을 사용하는 경우
 
     <bean id="serviceLoader" class="com.poscoict.glueframework.biz.control.GlueServiceDBLoader">
         <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"/>
