要使用定时任务，需要将quartz-1.5.2.jar加入lib，没有的话可以从下面地址下载：

 

有了这个再做个配置文件appctx-quartz.xml：

     
         
              
                   
                        
                     
                
           
               
              
               
                       
        
         0 17 21 ? * SAT
         
                
           
                  
              
               
           
              
          
      
     

被调用的类如下：

package com.ufo.unknown.quartz;public class Test{    public void print(){        System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>");    }}

然后在周六的21点17分0秒，Test类的print函数就被调用了，控制台输出如下：
