定义好定时任务的相关类，在类中调用dao或者service的时候会报空指针异常，
在定时任务的类上加注解@DisallowConcurrentExecution就可以注入service和dao了
@DisallowConcurrentExecution public class QuartzTask extends QuartzJobBean{ @Resource(name="appointmentServiceImpl") private AppointmentService appointmentService;//这是服务类 @Override protected void executeInternal(JobExecutionContext context) throws JobExecutionException { List<Appointment> appointments = appointmentService.getAppointments();//获取数据 System.err.println(appointments); } }
