创建评估器失败

Error message

创建评估器失败

What it means

EvaluatorServiceImpl.create() inserts the evaluator via evaluatorMapper.insert(evaluatorDO) and throws RuntimeException("创建评估器失败") ("failed to create evaluator") when the insert returns <= 0 affected rows. The domain validation already passed, so this signals the database rejected or silently skipped the INSERT.

Solutions

1. Check server logs / enable MyBatis SQL logging and inspect the underlying SQLIntegrityConstraintViolationException or duplicate-key error.
2. Verify all required evaluator fields are set before insert (name, type, etc.) and that any referenced IDs exist.
3. Confirm the evaluator table schema matches the entity (run pending migrations).

Example fix

// before
service.create(requestWithNameThatAlreadyExists); // duplicate key -> 0 rows -> RuntimeException
// after
if (evaluatorMapper.findByName(request.getName()) == null) {
    service.create(request);
}

if (request.getName() == null || request.getType() == null) {
    throw new IllegalArgumentException("name and type are required to create an evaluator");
}

try {
    return service.create(request);
} catch (RuntimeException e) {
    // inspect cause for DataIntegrityViolationException / duplicate key
    log.error("Evaluator insert failed", e);
    throw new ResponseStatusException(HttpStatus.CONFLICT, "evaluator could not be created (duplicate or constraint?)");
}

When it happens

Trigger: INSERT violating a DB constraint (NOT NULL column, unique name/index on evaluator, FK to a nonexistent owner/dataset); table schema drift after migration; mapper XML/annotation insert statement misconfigured.

Common situations: Creating an evaluator whose type/name duplicates an existing row under a unique constraint; missing required columns after a schema upgrade; inserting into the wrong table because of a copied mapper config.
