예제 Application 작성

Eclipse에서 Java Project 를 생성합니다.
그리고 다음 6개 파일을 생성합니다. 실행시 필요한 라이브러리는 GlueSDK에 포함되어 있습니다.

• applicationContext.xml : applicationContext.xml 이라는 고정 파일명(GlueAPI 참고)으로 기본적으로 실행환경에 존재해야하며, serviceManager bean을 항상 포함하고 있어야 합니다.

  <?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
                          http://www.springframework.org/schema/beans/spring-beans-3.2.xsd">
      <bean id="serviceManager" class="com.poscoict.glueframework.biz.control.GlueServiceManagerImpl">
          <property name="cacheManager" ref="cacheManager" />
          <property name="serviceLoader" ref="serviceLoader" />
      </bean>
      <bean id="cacheManager" class="com.poscoict.glueframework.cache.ehcache.GlueEhCacheManager"/>
      <bean id="serviceLoader" class="com.poscoict.glueframework.biz.control.GlueServiceLoader"/>
  </beans>
  

• ehcache.xml : applcationContext.xml 에 정의된 cacheManager 가 필요로 하는 EhCache 설정파일입니다.
  EhCache CacheManager 대신에 JCS CacheManager로 교체될 경우 JCS 설정파일이 필요합니다.

  <?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__">
      <cache name="_default-region" maxElementsInMemory="500" eternal="true" />
      <cache name="_service-region" maxElementsInMemory="500" eternal="true" />
  </ehcache>
  

• logback.xml : 로깅을 위해 Logback 을 사용할 경우 Logback 설정파일입니다.
  Logback 대신에 log4j 등 다른 로깅구현체를 사용할 수 있으며, 그에 맞는 설정파일이 필요할 수 있습니다.

  <?xml version="1.0" encoding="UTF-8"?>
  <configuration>
      <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
          <encoder>
              <pattern>[%thread] %-5level %logger - %msg%n</pattern>
          </encoder>
      </appender>
      <logger name="com.poscoict">
          <level value="debug" />
      </logger>
      <logger name="org.springframework">
          <level value="info" />
      </logger>
      <root level="warn">
          <appender-ref ref="CONSOLE" />
      </root>
  </configuration>
  

• hello-service.xml : 기본 실행단위 (Glue Service)

  <?xml version="1.0" encoding="UTF-8"?>
  <service name="hello-service" initial="HelloActivity" xmlns="http://www.poscoict.com/glueframework/service">
      <activity name="HelloActivity" class="sample.activity.HelloActivity">
          <transition name="success" value="end"/>
      </activity>
  </service>
  

• HelloActivity.java : Sample Activity

  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 HelloActivity extends GlueActivity<GlueContext>
  {
      @Override
      public String runActivity( GlueContext ctx )
      {
          System.out.println( "ServiceName : " + ctx.get( GlueBizControlConstants.SERVICE_NAME ) );
          System.out.println( "This is '" + this.getName() + "' activity" );
  
          Object input = ctx.get( "input" );
          System.out.println( "data : " + input );
  
          Object output = "Hello " + input + "!!!";
          ctx.put( "result", output );
  
          return GlueBizControlConstants.SUCCESS;
      }
  }
  

• Test.java : 테스트용

  package test;
  
  import com.poscoict.glueframework.biz.control.GlueBizControlConstants;
  import com.poscoict.glueframework.biz.control.GlueBizController;
  import com.poscoict.glueframework.biz.control.GlueBizProvider;
  import com.poscoict.glueframework.context.GlueContext;
  import com.poscoict.glueframework.context.GlueDefaultContext;
  
  public class Test
  {
      public static void main( String[] args )
      {
          GlueContext ctx = new GlueDefaultContext();
          ctx.put( GlueBizControlConstants.SERVICE_NAME, "hello-service" );
          ctx.put( "input", "Glue" );
  
          GlueBizController controller = GlueBizProvider.getController();
          controller.doAction( ctx );
  
          System.out.println( ctx.get( "result" ) );
      }
  }
