尝试将 Spring Boot 应用程序部署到谷歌云时，必须提供数据库名称错误

Question

我正在将 Spring Boot Web 应用程序部署到谷歌云。该应用程序在本地运行良好。我能够启动应用程序并且一切正常。但是当我尝试将它部署到谷歌云时，我收到以下错误：

java.lang.IllegalArgumentException: A database name must be provided.

我按照本教程部署应用程序：https://www.baeldung.com/spring-boot-google-app-engine

Answer 1

我通过将 application-gcp.properties 中的所有内容移动到 application.properties 来解决这个问题。 像这样：

（应用程序属性）

spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver
spring.jpa.hibernate.ddl-auto=none
spring.datasource.url=jdbc:mysql://35.***.***.**:3306/name_db
spring.datasource.username=root
spring.datasource.password=mypass
spring.datasource.initialization-mode=always
server.port = 8080
spring.jpa.properties.hibernate.dialect: org.hibernate.dialect.MySQL5Dialect

#Here added:
spring.cloud.gcp.sql.instance-connection-name=name-project:us- 
central1:instance-name
spring.cloud.gcp.sql.database-name=name_db

Answer 2

看起来发生这种情况是因为默认情况下启用了 GCP SQL 并且需要正确的连接。 但是如果你不需要它，例如在本地开发期间 - 只需在 application.properties 中禁用 gsp sql：

spring.cloud.gcp.sql.enabled=false

在添加 spring-cloud-gcp-starter-secretmanager 工件后出现了对我来说有趣的相同问题。
