Как я могу исправить ошибку с помощью Java, Spring, Gemini AI, Google Cloud Vertex AI: ваши учетные данные по умолчанию ⇐ JAVA

[Anonymous]

Я создал небольшой тестовый проект с использованием Java и Spring Boot для интеграции с Google Gemini AI.
Для этого я добавил зависимость к библиотеке google-cloud-vertexai для мой pom.xml:

Код: Выделить всё

  


com.google.cloud
libraries-bom
26.49.0
import
pom






com.google.cloud
google-cloud-vertexai

После этого я добавил вот такой простой контроллер:

Код: Выделить всё

package com.example.testing.controller;

import com.google.cloud.vertexai.VertexAI;
import com.google.cloud.vertexai.api.GenerateContentResponse;
import com.google.cloud.vertexai.api.PredictionServiceClient;
import com.google.cloud.vertexai.generativeai.GenerativeModel;
import com.google.cloud.vertexai.generativeai.ResponseHandler;
import java.io.IOException;
import lombok.RequiredArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@Slf4j
@RestController
@RequestMapping("/test")
@RequiredArgsConstructor
public class TestController {

private final PredictionServiceClient predictionServiceClient;

@GetMapping
public ResponseEntity test(@RequestParam String textPrompt) {
String projectId = "vertex-ai-java-api-for-gemini";
String location = "us-central1";
String modelName = "gemini-1.5-flash-001";

String output = textInput(projectId, location, modelName, textPrompt);
return ResponseEntity.ok(output);
}

public String textInput(String projectId, String location, String modelName, String textPrompt) {
try (VertexAI vertexAI = new VertexAI(projectId, location)) {
GenerativeModel model = new GenerativeModel(modelName, vertexAI);
GenerateContentResponse response = model.generateContent(textPrompt);
return ResponseHandler.getText(response);
} catch (IOException e) {
String errorMessage = "Error occurred: " + e.getMessage();
log.error(errorMessage, e);
throw new RuntimeException(errorMessage);
}
}
}

Когда я запускаю свое приложение, я получаю следующую ошибку:

Затем я добавил env var GOOGLE_APPLICATION_CREDENTIALS с путем к JSON-файлу с ключом из моей учетной записи службы Google, и все стало работать хорошо, но что, если я захочу перенести эту интеграцию в среду DEV или среду PROD, где я могу столкнуться с проблемой DevOps из-за местоположения JSON-файла и переменной env. Есть ли способ избежать использования JSON-файла и env var и установить учетные данные программным способом, например, как я программно установил идентификатор проекта или местоположение региона в моем примере кода?
Если вы знаете способ использовать Gemini AI из приложения Java и избегать аутентификации, это тоже будет очень полезная информация.
Заранее спасибо!
