最流行的java后台框架spring quartz定时任务

public interface IMyTestService { 
    public void myTest(); 
} 

@Component //import org.springframework.stereotype.Component; 
public class MyTestServiceImpl implements IMyTestService { 
   @Scheduled(cron="0/5 * * * * ? ")  //每5秒执行一次 
   @Override 
   public void myTest(){ 
      System.out.println("进入测试"); 
   } 
}
