关于时间配置可参考另一篇http://www.cnblogs.com/stit/p/4013398.html

我的项目的应用

1 knowledge-schedule.xml 不要忘了在spring总配置文件中引入

调度工厂没有加lazy-init="false"

2 ColumnTimerTasker

3另一哥们写的RankTask，用到了线程池

package com.ginkgocap.ywxt.knowledge.util;


import java.util.concurrent.Future;

import javax.annotation.Resource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import org.springframework.stereotype.Component;
  
/**
 * 排行任务
 * <p>于2014-9-11 由 创建 </p>
 * @author  <p>当前负责人  </p>     
 *
 */
@Component("rankTask")
public class RankTask {

    @Resource
    ThreadPoolTaskExecutor threadPoolTaskExecutor;
    @Autowired
    RankSchedule schedule;
    
    public void startStatistics(String[] obj) {
        schedule.setObj(obj);
        Future future = threadPoolTaskExecutor.submit(schedule);
        // future.get();
    }
}

package com.ginkgocap.ywxt.knowledge.util;

import java.util.concurrent.Callable;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

/**
 * 排行计划
 * <p>于2014-9-11 由  创建 </p>
 * @author  <p>当前负责人 </p>     
 */
@Component
public class RankSchedule implements Callable<String> {

    @Autowired
    private RankStatistic rs;

    private String[] obj;

    public String[] getObj() {
        return obj;
    }

    public void setObj(String[] obj) {
        this.obj = obj;
    }

    @Override
    public String call() throws Exception {
        rs.run(obj[0]);
        return null;
    }

}
