 Использование внедрения Vertex AI в приложении Spring Boot

Сообщение Anonymous »

Я собираюсь использовать Google VertexAI Text Embeddings для встраивания текста перед сохранением в pgvectordb.

Я проверил подключение к GCP с помощью этой программы в Spring Boot (помощь в этом вопросе по аутентификации Spring-boot-google-vertex-ai):

import com.google.auth.oauth2.GoogleCredentials;
import com.google.auth.oauth2.ServiceAccountCredentials;
import org.springframework.boot.CommandLineRunner;

import java.io.IOException;

@Component
public class CredentialCheck implements CommandLineRunner {

@Override
public void run(String... args) {
System.out.println("----------------------------------------");
System.out.println("🔍 TESTING GOOGLE CLOUD CREDENTIALS...");
System.out.println("----------------------------------------");

try {
// 1. Load credentials exactly how Spring AI does it
GoogleCredentials credentials = GoogleCredentials.getApplicationDefault();

// 2. ADD SCOPE
if (credentials.createScopedRequired()) {
credentials = credentials.createScoped("https://www.googleapis.com/auth/cloud-platform",
"https://www.googleapis.com/auth/cloud-platform.read-only");
}

// 3.  Now try to refresh
credentials.refreshIfExpired();

System.out.println("✅ SUCCESS! Credentials Valid & Active.");

if (credentials instanceof ServiceAccountCredentials) {
System.out.println("🆔 Identity: " + ((ServiceAccountCredentials) credentials).getClientEmail());
System.out.println("📂 Source: JSON Key File (Docker Ready)");
}

} catch (Exception e) {
System.err.println("❌ FAILED: " + e.getMessage());
}

System.out.println("----------------------------------------");
}
}
и вывод был УСПЕШНЫМ.

Вышеупомянутые учетные данные, к которым он получил доступ через файл json, который я скачал с консоли GCP, и указал переменную среды Windows на ее местоположение:

Чтобы запустить этот тест, я прокомментировал две зависимости и прокомментировал строки сохранения вложений в базе данных pgvector из этого кода уровня службы:

@Service
public class HeelpDataService {

private final HeelpDataRepository repository;
private final VectorStore vectorStore; //COMMENTED this and all the methods, constructors etc.  while testing GCP connectivity

@Autowired
public HeelpDataService(HeelpDataRepository repository, VectorStore vectorStore) {
this.repository = repository;
this.vectorStore = vectorStore;
}

public HeelpData createData(HeelpData data) {
HeelpData savedData = repository.save(data);
// syncToVectorStore(savedData);
return savedData;
}

public List getAllData() {
return repository.findAll();
}

public Optional getDataById(Long id) {
return repository.findById(id);
}

public HeelpData updateData(Long id, HeelpData dataDetails) {
return repository.findById(id).map(existingData -> {
existingData.setUrl(dataDetails.getUrl());
existingData.setText_content(dataDetails.getText_content());
HeelpData savedData = repository.save(existingData);

// Sync to vector store: simpler approach is to delete old and add new
// Assuming source_id is unique enough for us to use for deletion
deleteFromVectorStore(id);
syncToVectorStore(savedData);

return savedData;
}).orElse(null);
}

public void deleteData(Long id) {
repository.deleteById(id);
deleteFromVectorStore(id);
}

private void syncToVectorStore(HeelpData data) {
if (data.getText_content() != null && !data.getText_content().isEmpty()) {
// Use the HeelpData ID as the Document ID for easy retrieval/deletion
Document document = new Document(data.getId().toString(),
data.getText_content(),
Map.of("source_id", data.getId(), "url", data.getUrl()));
vectorStore.add(List.of(document));
}
}

private void deleteFromVectorStore(Long id) {
// Delete using the ID we assigned (HeelpData ID ->  String)
vectorStore.delete(List.of(id.toString()));
}
}
Но после успешного тестирования GCP, когда я раскомментирую и пытаюсь сохранить в pgvector, я получаю журнал ошибок:
