Unexpected error occurred in scheduled task

回答: 在使用@Scheduled注解进行定时调度时，可能会遇到"Unexpected error occurred in scheduled task"的错误。这个错误通常是由于在服务启动时，@Scheduled注解的执行级别高于spring @Resource资源注入的级别，导致自动注入失败。解决这个问题的办法是创建一个ScheduleConfig类，并实现ApplicationContextAware接口，通过该类获取ApplicationContext，并提供一个静态方法用于获取bean。这样，在定时任务中可以通过该方法获取需要的bean，避免自动注入失败的问题。具体的解决办法如下所示：

@Component
public class ScheduleConfig implements ApplicationContextAware {
private static ApplicationContext context;

@Override
public void setApplicationContext(@NotNull ApplicationContext applicationContext) throws BeansException {
context = applicationContext;
}

public static <T> T getBean(Class<T> clazz) {
return context != null ? context.getBean(clazz) : null;
}
}

通过以上的解决办法，你可以在定时任务中使用ScheduleConfig.getBean()方法获取需要的bean，避免自动注入失败的问题。
