（2）定时任务

@Slf4j
public class CapsuleSendingTask implements Runnable {    /**
     * 存储时间胶囊
     */
    private final Letter letter;    public CapsuleSendingTask() {
        letter = new Letter();
    }    /**
     * 构造器
     *
     * @param letter 发送的信件
     */
    public CapsuleSendingTask(Letter letter) {
        this.letter = letter;
    }    @Override
    public void run() {
        // 时间胶囊数量减1
        reduceCapsule();        LetterServiceImpl letterService = BeanUtils.getBean(LetterServiceImpl.class);
        letter.setReceiveTime(LocalDateTime.now());        if (letterService.updateById(letter)) {
            log.info("发送id为{}的letter成功，接收时间：{}", letter.getLetterId(), letter.getReceiveTime());
            //发送通知
            this.sendNotice();
        } else {
            log.error("发送id为{}的letter失败", letter.getLetterId());
            throw new BizException("发送失败[id=" + letter.getLetterId() + "]");

        String content = "你收到一个来自自己的时间胶囊，快去查收吧！";
        notice.setContent(content);

        noticeMapper.insert(notice);
        log.info("发送notice成功，内容为{}", content);
    }    /**

                "letter=" + letter +
                '}';
    }
}

（3）删除树洞

@Override
public int deleteTreeHoleById(int id,Integer userId) {
        log.info("正在删除id为{}的treeHole", id);
        if(!userId.equals(treeHoleMapper.getUserIdByTreeId(id))){
            log.error("更新id为{}的treeHole失败,登录用户与树洞拥有用户不同",id);
            throw new BizException("登录用户与树洞拥有用户不同");
        }
        if (super.removeById(id)) {
            log.info("删除id为{}的treeHole成功", id);
            return id;
        } else {
            log.error("删除id为{}的treeHole失败", id);
            throw new BizException("删除失败[id=" + id + "]");
        }
}
