在android项目中要使用到定时调用接口来更新数据库中的战力称号...（类似王者荣耀的称号）

@Component
@Configuration //1.主要用于标记配置类，兼备Component的效果。
@EnableScheduling // 2.开启定时任务
public class SetTitleScheduled {
@Resource
UserMapper userMapper;
@Resource
RegionMapper regionMapper;
@Resource
IRegionService regionService;
//3.添加定时任务,每天凌晨0点更新一次
@Scheduled(cron = "0 0 0 * * ?")
//或直接指定时间间隔，例如：5秒
//@Scheduled(fixedRate=5000)
private void configureTasks() throws Exception {
System.err.println("执行静态定时任务时间: " + LocalDateTime.now());
