我在IntelliJ IDEA中打开一个终端并运行以下命令：

export GOOGLE_APPLICATION_CREDENTIALS="/Users/nunyito/IdeaProjects/mystic-river-api/src/main/resources/google-gemini/mysticriver.json"

字符串
我在json文件中有这个：

{
  "type": "service_account",
  "project_id": "mysticriver,
  "private_key_id": "c81d561c1z65159b925ddd7a00c895358855b855c",
  "private_key": "-----BEGIN PRIVATE KEY-----\nREDACTED\n-----END PRIVATE KEY-----\n",
  "client_email": "service-account-for-mystic-riv@mysticriver.iam.gserviceaccount.com",
  "client_id": "117167372461671003080",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
  "token_uri": "https://oauth2.googleapis.com/token",
  "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
  "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/service-account-for-mystic-riv%40mysticriver.iam.gserviceaccount.com",
  "universe_domain": "googleapis.com"
}

型
然后我运行这个服务：

@Service
public class GoogleGeminiService {
    public static void main(String[] args) throws Exception {
       
        String projectId = "MysticRiver";
        String location = "us-central1";
        String modelName = "gemini-pro-vision";
        String output = simpleQuestion(projectId, location, modelName);
        System.out.println(output);
    }
}

型
但我犯了个错误

...context/6.1.1/spring-context-6.1.1.jar com.mysticriver.service.GoogleGeminiService
Exception in thread "main" java.io.IOException: Your default credentials were not found. To set up Application Default Credentials for your environment, see https://cloud.google.com/docs/authentication/external/set-up-adc.
