1、定制调度任务：

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import com.rd.ifaes.core.project.domain.Project;

/**
 * 项目缓存延时调度任务
 * @author lh
 * @version 3.0
 * @since 2016-8-26
 *
 */
public class ProjectCacheDelaySchedule implements Runnable {
	
	private final static Logger LOGGER = LoggerFactory.getLogger(ProjectCacheDelaySchedule.class);
	
	//项目信息
	private Project project;
	//延时时间（单位：秒）
	private long delay;
	
	public ProjectCacheDelaySchedule(Project project) {
		super();
		this.project = project;
		delay = project.getShowTime().getTime() - System.currentTimeMillis();
		delay = (delay > 0) ? delay / 1000 : 0;
	}
	
	/**
	 * 取得延时时间
	 * @return
	 */
	public long getDelay() {
		return delay;
	}

	/**
	 * project添加到缓存
	 */
	@Override
	public void run() {
		LOGGER.info("project to cache, projectNo="+project.getProjectNo());
		ProjectCache.setProject(project);
	}
	
}

2、加入调度任务：

	private static ScheduledExecutorService projectSaleService = Executors.newScheduledThreadPool(1);
	/**
	 * 项目上架 ( 仅供后台产品或借贷上架用 )
	 * @param project
	 */
	public static void projectSale(Project project){
		ProjectCacheDelaySchedule executor = new ProjectCacheDelaySchedule(project);
		projectSaleService.schedule(executor, executor.getDelay(), TimeUnit.SECONDS);
	}

The end!
