I have downloaded Spring3 and Quartz and Spring batch Framework.
After running a simple example, It was not easy, not working well with autowired annotation and many things to learn before use giant functions. currently, Spring batch depend on spring 2.5 that I am not sure, it will work well with Spring 3.1
It is also causing to make big packaging jar/war file
I just wanted to make a very simple batch program that I can use based on SpringFramwork which can autowire beans and DB resources.
I decide to use Spring Task. It just need Spring framework, nothing else
It is extreamly simple and works perfect as I expected.
Just type 3 more line on you spring xml file

Make one Class that is Component annotated. The Class must be in base-package or sub package.
and make method that is Scheduled annotated with Cron Expression.
That's it. that it will run every 5 minutes from 2 min of the hour.
You can autowire beasn which you like.
package monitor.batch;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
@Component
public class HarvestHttpStatusJob {
private final Log logger = LogFactory.getLog(this.getClass());
//To-do @Autowired beans as usual you need.
@Scheduled(cron = "0 2/5 * * * *")
public void harvestStatus() {
logger.info(this.getClass().getName() + " Start");
//To do Implement your code
logger.info(this.getClass().getName() + " Finish");
}
}
