尝试更新不存在的数据项

Error message

尝试更新不存在的数据项: {}

What it means

DatasetItemServiceImpl.update checks whether the dataset item exists before updating. If it does not exist, it only logs '尝试更新不存在的数据项' (updating non-existent item) as a warning and then proceeds to call datasetItemMapper.update anyway — the update silently affects 0 rows and getById returns null or stale data. Unlike deleteById, it does not throw.

Solutions

1. Fix the bug: throw after the warning (as deleteById does) or check the update's return count and throw if 0 rows affected
2. Verify the item id exists (SELECT) before calling update from the client
3. Check for concurrent deletes racing with updates; use optimistic locking or version columns

Example fix

// before
if(Objects.isNull(existingData)){
    log.warn("尝试更新不存在的数据项: {}", request.getId());
}
datasetItemMapper.update(request.getId(),request.getDataContent());
// after
if(Objects.isNull(existingData)){
    log.warn("尝试更新不存在的数据项: {}", request.getId());
    throw new RuntimeException("数据项不存在: " + request.getId());
}

DatasetItemDO item = datasetItemMapper.selectById(id);
if (item == null) throw new RuntimeException("数据项不存在: " + id);
// only then call update

boolean itemExists(Long id) { return id != null && datasetItemMapper.selectById(id) != null; }

try { service.update(req); }
catch (RuntimeException e) {
    if (e.getMessage().startsWith("数据项不存在")) { return ResponseEntity.status(404).body(e.getMessage()); }
    throw e;
}

When it happens

Trigger: update(request) is called with a request.getId() that has no matching row in the dataset item table — already deleted, wrong id, or id from another dataset/environment.

Common situations: Client caching stale ids after a concurrent delete; UI submitting an edit for an item deleted in another tab; copy-pasted ids between dev/prod databases.
