Quartz使用-入门使用

注：这里使用的是Quartz1.6.5版本(包：quartz-1.6.5.jar)

//测试main函数

        Date d = new Date();
        String returnstr = DateFormat.format(d);          

        TestJob job = new TestJob();
        String job_name ="11";
        try {
            System.out.println(returnstr+ "【系统启动】");
            QuartzManager.addJob(job_name,job,"0/2 * * * * ?"); //每2秒钟执行一次  

//            Thread.sleep(10000);

        }  catch (Exception e) {
            e.printStackTrace();
        }
