尝试删除不存在的数据项

Error message

尝试删除不存在的数据项: {}

What it means

DatasetItemServiceImpl.deleteById verifies the item exists and throws RuntimeException('数据项不存在: <id>') when it doesn't, after logging '尝试删除不存在的数据项'. This is a hard failure surfaced to the caller as an unchecked exception.

Solutions

1. Handle or avoid the duplicate delete: make the client tolerate 'not found' (idempotent delete) or check existence first
2. Refresh the frontend list after deletes so stale ids are not resubmitted
3. Catch the RuntimeException in the controller and map it to a 404 response
4. Verify the id against the correct database/environment

Example fix

// before
service.deleteById(itemId); // throws on second call
// after
try { service.deleteById(itemId); }
catch (RuntimeException e) {
    if (e.getMessage().startsWith("数据项不存在")) { /* already deleted, ok */ }
    else throw e;
}

DatasetItemDO item = datasetItemMapper.selectById(id);
if (item == null) { /* skip delete or warn: already gone */ }

boolean itemExists(Long id) { return id != null && id > 0 && datasetItemMapper.selectById(id) != null; }

try { service.deleteById(id); }
catch (RuntimeException e) {
    if (e.getMessage().startsWith("数据项不存在")) { log.info("item {} already deleted", id); }
    else throw e;
}

When it happens

Trigger: deleteById(id) with a positive, non-null id that has no row in the dataset item table — item already deleted, wrong id, or cross-environment id.

Common situations: Double-delete from retries or UI double-click; stale list data in the frontend; deleting by id from another dataset.
