分析原因：
Spring 事务嵌套造成死锁。FileServiceImpl 里嵌入了 OperationService：
- private OperationService operationService;
FileServiceImpl 的 delete 方法里对 MySQL 的 file 表有操作，而 OperationService 里的 revokeSharedFolder 方法也对同一张表有更新操作。事务嵌套，造成死锁。
解决方案：
当前调用事务的方法设置为 Propagation.SUPPORTS：
- @Transactional(propagation=Propagation.SUPPORTS)//by Defonds,for BUG094537
- @Override
- public void delete(int uid, int[] itemIds) {
- if (itemIds != null && itemIds.length > 0) {
