评测集名称不能为空

Error message

评测集名称不能为空

What it means

Input validation failure in DatasetServiceImpl.create. The method requires a non-blank dataset name before persisting the new dataset; when DatasetCreateRequest.getName() is null, empty, or whitespace-only, IllegalArgumentException is thrown inside the @Transactional method, rolling back any partial writes. This is a client-side request problem: the caller must supply a name before retrying.

Solutions

1. Set a non-empty name on DatasetCreateRequest before calling create
2. Add @NotBlank on the request DTO's name field for earlier, standardized validation
3. Fix the JSON payload key so it matches the DTO field name
4. Validate input in the controller with @Valid and return a 400

Example fix

// before
DatasetCreateRequest req = new DatasetCreateRequest();
req.setDescription("eval set");
datasetService.create(req);
// after
DatasetCreateRequest req = new DatasetCreateRequest();
req.setName("my-eval-set");
req.setDescription("eval set");
datasetService.create(req);

if (request.getName() == null || request.getName().isBlank()) { throw new IllegalArgumentException("name is required"); }

boolean hasName(DatasetCreateRequest r) { return r != null && r.getName() != null && !r.getName().isBlank(); }

try { datasetService.create(req); } catch (IllegalArgumentException e) { return ResponseEntity.badRequest().body(e.getMessage()); }

When it happens

Trigger: POSTing a DatasetCreateRequest with name omitted, empty string, or whitespace; JSON deserialization leaving name null due to a wrong field name in the payload.

Common situations: Front-end form allowing empty submit; API client sending "title" instead of "name"; automated scripts with partial payloads.
