1、现在想要获得在特定时间或者指定时间执行相应功能有两种做法在applicationContext.xml中写入如下Bean       1000      

2、ame="period">   3600000                  true  

3、uler"  class="org.springframework.scheduling.timer.TimerFactoryBean">                

4、ice">            然后写SampleTask类，如下：packagecom.css.wam.portlet;importjava.util.ArrayList;importjava.util.Calendar;importjava.util.Iterator;importjava.util.List;importj

5、ava.util.TimerTask;importjavax.servlet.ServletContext;字串2importorg.apache.jetspeed.security.SecurityException;字串9importcom.css.wam.service.WorkService;字串1@SuppressWarnings("unused")classSampleTaskextendsTimerTask{   字串2   privatestaticfinalintC_SCHEDULE_HOU

6、R=23;//设置指定时间   privateWorkServiceworkService;   privateListusers;   privateListteams;   privateWorkPortletwork;     publicvoidsetWorkService(WorkServiceworkService){  this.workService=workService;}字串7publicvoidsetWork(WorkPortletwork){  this.work=work;}字串4

7、   publicSampleTask(){   }     @SuppressWarnings("unchecked")publicvoidrun(){         Calendarcal=Calendar.getInstance();       try{         users=work.getUsers();         teams=newArrayList();      for(Iteratorit=users.iterator();it.hasNext();)      {     

8、  Stringteamname=work.getGroupsByUser((String)it.next());       teams.add(teamname);      }           //查看当前时间与指定是否一致，一致则执行任务            if(C_SCHEDULE_HOUR==cal.get(Calendar.HOUR_OF_DAY))字串6
