如何在 Spring Boot 应用程序中设置 GOOGLE_APPLICATION_CREDENTIALS [英] How to set GOOGLE_APPLICATION_CREDENTIALS in spring boot app

问题描述

我正在尝试在 Java 中使用谷歌视觉库.这些步骤指定我需要设置我的身份验证凭据才能开始使用 this 图书馆.我能够从 API 控制台凭据页面生成我的 json 属性文件，并将其放置在资源文件夹中的 Spring Boot 应用程序中.

I am attempting to use the google vision library in java. The steps specify that I need to setup my auth credentials in order to start using the this library . I was able to generate my json property file from API Console Credentials page and I placed it in my spring boot app in the resources folder.

我认为更新了我的 application.properties 文件以包含如下值:

I think updated my application.properties file to include the value like so:

GOOGLE_APPLICATION_CREDENTIALS=datg-avatar-generator-9dc9155cd5bd.json

我也在我的控制器中设置我的属性源，如下所示:

I'm also setting my property source in my controller like so:

@PropertySource("${GOOGLE_APPLICATION_CREDENTIALS}")

但是，在这样做之后，我仍然收到一条错误消息:

However, after doing that I'm still getting an error saying:

java.io.IOException: The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials. See https://developers.google.com/accounts/docs/application-default-credentials for more information.
