Heroku 上的 Spring Boot + 雲 API 部署

Question

我正在嘗試在 heroku 上部署由 google 提供的簡單應用程序： https : //github.com/GoogleCloudPlatform/java-docs-samples/tree/master/vision/spring-framework 。

我已經完成了此線程中的建議如何在 Heroku 上使用 Google API 憑據 json？ . 但我仍然收到錯誤。 我什至不確定它的谷歌憑據錯誤還是其他什么。 僅用於記錄應用程序在本地工作。

這是pom.xml文件，我已經進行了一些更改，因此它不是 github 項目的克隆

Answer 1

puedes intentar con el archivo de configuración de spring-boot y colocar esta configuración。

spring.cloud.gcp.credentials.location=classpath:archivoPermisos.json
spring.cloud.gcp.project-id=idproyecto
spring.cloud.gcp.vision.enabled=true
spring.cloud.gcp.core.enabled=true

蘇爾特。
