GlueService Manager – meta-access

ServiceLoader 설정

Application의 용도에 따라 GlueService Meta와 관련된 bean 설정을 수정합니다.
Web Appliclation 용도일 경우엔 MetaData 동기화와 관련된 Cache 설정도 수정합니다.

Web Application 용
Scheduled Job Application 용

serviceLoader 의 class 속성 값은 com.posco.glue.reuse.PoscoServiceLoader 로 변경합니다.
serviceLoader 의 dataSource property의 값은 Meta용 DataSource를 참고하도록 합니다.
serviceLoader 의 queryExtraBindingInfo property의 값은 법인코드를 입력합니다( 상수, 변수 가능)
queryLoader 의 extraQueryFiles property에 libquery/posco-meta-access-query.glue_sql 를 추가합니다.

<bean id="serviceLoader" class="com.posco.glue.reuse.PoscoServiceLoader">
    <property name="dataSource" ref=". . ."/>
    <property name="queryManager" ref="queryManager"/>
    <property name="queryExtraBindingInfo">
        <list>
            <value>. . .</value>
        </list>
    </property>
</bean>
. . .
<bean id="queryLoader" class="com.poscoict.glueframework.dao.manager.GlueQueryLoader">
    <property name="extraQueryFiles">
        <list>
            . . .
            <value>libquery/posco-meta-access-query.glue_sql</value>
        </list>
    </property>
</bean>

serviceLoader 의 dataSource property의 값은 다음과 같이 2가지 중 하나로 설정할 수 있습니다.

Web Application 용의 dataSource

<bean id="serviceLoader" class="com.posco.glue.reuse.PoscoServiceLoader">
    <property name="dataSource" ref="m0a-ds"/>
    . . .
</bean>
<bean id="m0a-ds" class="org.springframework.jndi.JndiObjectFactoryBean"> 
    <property name="jndiName" value="jdbc/rw/M00A10DS"/> 
    . . . 
</bean>

Scheduled Job Application 용의 dataSource

<bean id="serviceLoader" class="com.posco.glue.reuse.PoscoServiceLoader">
    <property name="dataSource" ref="m0a-ds"/>
    . . .
</bean>
<bean id="m0a-ds" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>
    <property name="url" value=". . ." />
    <property name="username" value=". . ." />
    <property name="password" value=". . ." />
    <property name="defaultAutoCommit" value="false" />
    <property name="minIdle" value="0" />
    <property name="maxActive" value="-1" />
    <property name="maxIdle" value="1000" />
</bean>

serviceLoader 의 queryExtraBindingInfo property의 값은 다음과 같이 2가지 중 하나로 설정할 수 있습니다.

상수 사용 queryExtraBindingInfo

<bean id="serviceLoader" class="com.posco.glue.reuse.PoscoServiceLoader">
    . . .
    <property name="queryExtraBindingInfo">
        <list>
            <value>BZ</value>
        </list>
    </property>
</bean>

변수 사용 queryExtraBindingInfo

<bean id="serviceLoader" class="com.posco.glue.reuse.PoscoServiceLoader">
    . . .
    <property name="queryExtraBindingInfo">
        <list>
            <value>${GCS_COMP_CODE}</value>
        </list>
    </property>
</bean>

CacheManager 설정

Application의 용도에 따라 캐싱과 관련된 bean 및 설정파일(ehcache.xml)을 수정합니다.
Web Appliclation 용도일 경우엔 MetaData 동기화 기능을 사용하기 위해 다음과 같이 수정합니다.

cacheManager 의 bean에 location property를 추가합니다(MetaData 동기화와 관련된 설정을 위해 ehcache.xml은 war에 패키징 하지 않습니다).

<bean id="cacheManager" class="com.poscoict.glueframework.cache.ehcache.GlueEhCacheManager">
    <property name="location" value="file:${CONFIG_PATH}/ehcache.xml"/>
</bean>

MetaData 동기화와 관련된 설정을 위해, ehcache.xml 에 cacheManagerPeerListenerFactory 을 다음과 같이 추가합니다.
cacheManagerPeerListenerFactory의 properties 속성의 hostName과 port 정보는 Meta Manager(M0AA20APP.ear)의 ehcache.xml 에 rmiUrls에 포함됩니다. (참고)

<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"
    updateCheck="false" name="__DEFAULT__">
    <cacheManagerPeerListenerFactory
        class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"
        properties="hostName=172.31.47.161, port=40001, socketTimeoutMillis=2000" />
    <cache ...>
</ehcache>

MetaData 동기화와 관련된 설정을 위해, ehcache.xml 에 <cache name="_service-region"..> 부분을 다음과 같이 수정합니다.
cache의 eternal 속성값은 false로 변경되며, 그외 추가 속성이 있습니다.
cache에 cacheEventListenerFactory 요소가 추가됩니다.

<cache name="_service-region" maxElementsInMemory="500" 
       maxElementsOnDisk="0" eternal="false" timeToIdleSeconds="0" timeToLiveSeconds="0" memoryStoreEvictionPolicy="LRU" >
    <cacheEventListenerFactory 
        class="net.sf.ehcache.distribution.RMICacheReplicatorFactory" 
        properties="replicateAsynchronously=true, replicatePuts=false, replicateUpdates=false, replicateUpdatesViaCopy=false, replicateRemovals=false" />
</cache>
