任务调度(ScheduledExecutorTask)

[Spring] 任务调度(ScheduledExecutorTask)

实现方法：

 

1、简单地建立一个Java类，该类需实现Runnable接口。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34

/*  * Copyright (c) 2010 - OZ Wizards Group.  * All rights reserved.  *  * Created on 2012-10-15  */ package cn.oz.oa.eduresource.tools;                             import cn.oz.oa.eduresource.service.EduResourceService;                             /**  * 定时扫描目录任务  * @author ozHu  * @since 5.2.0  */ public class ScanFolderTimeTask implements Runnable {                                 private EduResourceService eduResourceService;     public void setEduResourceService(EduResourceService eduResourceService) {         this.eduResourceService = eduResourceService;     }                                 @Override     public void run() {         String path="C:\\新建文件夹";         try {             if(null != eduResourceService)                      this.eduResourceService.createEduResource(path);                                                 } catch (Exception e) {             e.printStackTrace();         }     }                             }

 

2、Spring配置如下：

1 2 3 4 5 6 7 8 9 10 11 12

<bean id="eduResourceScanFolderTask" class="org.springframework.scheduling.concurrent.ScheduledExecutorTask">     <!-- 定义需要执行任务的类 -->         <property name="runnable">             <bean class="cn.oz.oa.eduresource.tools.ScanFolderTimeTask">                 <property name="eduResourceService" ref="eduResourceService" />             </bean>         </property>         <!-- 系统启动后，延迟50秒启动该任务 -->         <property name="delay" value="50000"/>         <!-- 每隔1小时重复执行一次该任务 -->         <property name="period" value="3600000"/>  </bean>

 

3、最后再配置实施该任务调度的任务（此配置应放置在web中的spring文件中）

1 2 3 4 5 6 7 8

<bean id="scheduledExecutorFactoryBean" class="org.springframework.scheduling.concurrent.ScheduledExecutorFactoryBean">         <property name="poolSize" value="5" />         <property name="scheduledExecutorTasks">             <list>                 <ref bean="eduResourceScanFolderTask"/>             </list>         </property> </bean>

如有多个任务，可如第一二步配置bean,然后把任务bean放到第三步list中。
