Job을 구현하는 방법은 2가지가 있습니다.
GlueService 구현
Java Class 구현
예약어 ServiceName 에 해당하는 job001-service 를 개발합니다.
설치파일( scheduler-server-<version>.zip )에 포함된 sample1.jar 을 참고하세요.
<?xml version="1.0" encoding="UTF-8"?>
<service name="job001-service" initial="Sleep" xmlns="http://www.poscoict.com/glueframework/service">
<activity name="Sleep" class="sample.activity.SleepActivity">
<transition name="success" value="end"/>
<property name="sleep-second" value="sleep-second"/>
</activity>
</service>
package sample.activity;
import com.poscoict.glueframework.biz.activity.GlueActivity;
import com.poscoict.glueframework.biz.control.GlueBizControlConstants;
import com.poscoict.glueframework.context.GlueContext;
public class SleepActivity extends GlueActivity<GlueContext>
{
@Override
public String runActivity( GlueContext ctx )
{
this.logger.info( "{}", this.getProperty( "sleep-second" ) );
this.logger.debug( "{}", this.getProperty( "sleep-second" ) );
this.logger.trace( "{}", this.getProperty( "sleep-second" ) );
this.logger.warn( "{}", this.getProperty( "sleep-second" ) );
this.logger.error( "{}", this.getProperty( "sleep-second" ) );
if ( this.getProperty( "sleep-second" ) != null )
{
int s = Integer.parseInt( ctx.get( this.getProperty( "sleep-second" ) ).toString() );
for ( int i = s * 10; i > 0; i-- )
{
this.logger.debug( "{}", i );
try
{
Thread.sleep( 100 );
} catch ( InterruptedException e )
{}
}
}
return GlueBizControlConstants.SUCCESS;
}
}
예약어 className 에 해당하는 sample.job.SamplePgm 를 구현합니다.
설치파일( scheduler-server-<version>.zip )에 포함된 sample2.jar 을 참고하세요.
com.poscoict.app.job.GlueJob interface를 상속합니다. (com.posco.glue.cm.PoscoSchedulerJob 은 deprecated 되었습니다.)
runProgram method를 구현시 try~catch 구문 안에서 biz 로직이 수행되도록 합니다.
biz 로직 수행시 발생된 모든 Error는 catch 구문에서 ctx 에 담습니다.
package sample.job;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.poscoict.app.job.GlueJob;
import com.poscoict.app.job.JobConstants;
import com.poscoict.glueframework.context.GlueContext;
// 1. interface
public class SamplePgm implements GlueJob
{
// 2. logger
Logger logger = LoggerFactory.getLogger( SamplePgm.class );
@Override
public void runProgram( GlueContext ctx )
{
// 3. try~catch
try
{
// 4. biz logic 시작~
this.logger.trace( "{}", ctx.entrySet() );
this.logger.trace( "REQUEST ID : {}", ctx.get( JobConstants.JOB_REQUEST_ID ) );
for ( String key : ctx.keySet() )
{
this.logger.trace( "{}={}", key, ctx.get( key ) );
}
this.logger.info( "Hello" );
this.logger.debug( "Hello" );
this.logger.trace( "Hello" );
this.logger.error( "Hello" );
this.logger.warn( "Hello" );
if ( ctx.get( "sleep-second" ) != null )
{
int s = Integer.parseInt( ctx.get( "sleep-second" ).toString() );
for ( int i = s * 10; i > 0; i-- )
{
this.logger.debug( "{}", i );
try
{
Thread.sleep( 100 );
} catch ( InterruptedException e )
{}
}
}
// 4. biz logic 끝~
} catch ( Throwable t )
{
ctx.setException( t );
}
}
}
sample1.jar 에 포함된 applicationContxt.xml 은 다음과 같습니다.
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans

biz 로직에서 DB를 사용하는 경우 아래를 참고해서 bean을 추가합니다.
placeholderConfig bean을 통해 DB 연결정보 등은 user-application.properties 에 설정할 수 있습니다.

로깅을 위해 다음 2가지 중 하나를 사용할 수 있습니다.
File Appender를 사용하고, file명은 log.file 이라는 변수로 지정합니다.
logback-text.xml 파일은 다음과 같습니다.
log.file 변수명은 예약어입니다.
<?xml version="1.0" encoding="UTF-8"?>
<configuration><!-- debug="true" -->
<appender name="FILE" class="ch.qos.logback.core.FileAppender">
<file>${log.file}</file>
<append>true</append>
<encoder>
<pattern>%d %-5level %logger - %msg%n</pattern>
</encoder>
</appender>
<logger name="org.springframework">
<level value="info" />
</logger>
<logger name="org.apache">
<level value="warn" />
</logger>
<logger name="net.sf.ehcache">
<level value="warn" />
</logger>
<logger name="com.posco">
<level value="trace" />
</logger>
<logger name="com.poscoict">
<level value="debug" />
</logger>
<root level="info">
<appender-ref ref="FILE" />
</root>
</configuration>
log4j.xml 파일은 다음과 같습니다.
log.file 변수명은 예약어입니다.
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j='http://jakarta.apache.org/log4j/'>

<param name="maxBackupIndex" value="20"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value = "%d %-5p - [%t]%C||%m%n"/>
</layout>
</appender>
<logger name="org.springframework">

</logger>
<logger name="org.apache">

</logger>
<logger name="net.sf.ehcache">

</logger>
<root>

</log4j:configuration>
main method를 만들어 실행합니다.
Job Parameter는 GlueDefaultContext를 이용합니다.
public static void main(String args[])
{
System.setProperty( "CONFIG_PATH", ... );
System.setProperty( "log.file", ... );
GlueContext ctx = null
// 1번 테스트
ctx = new GlueDefaultContext();
ctx.put( GlueBizControlConstants.SERVICE_NAME, "job001-service" );
ctx.put("sleep-second", "10");
GlueBizProvider.getController().doAction( ctx );
//2번 테스트
ctx = new GlueDefaultContext();
ctx.put("sleep-second", "5");
new SamplePgm().runProgram(ctx);
}
