定时任务类

@Componentpublic class QuartzDemo {    /**     * 定时任务     */    public void execute() {        System.out.println("ִ定时任务quartz已经调用:" + new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));    }}

applicationContext-quartz.xml

dubbo等有些约束在这个demo中用不上,根据需求选择

web.xml

       
           
      
       contextConfigLocation
            
      
       classpath:spring/applicationContext-quartz.xml
        
       
           
      
       org.springframework.web.context.ContextLoaderListener
        
     

启动工程即可看到控制台每5秒输出一次提示信息
