连接到 Cloud SQL 失败

Question

我正在尝试使用具有云编辑器角色的服务帐户连接到 GCP 云 sql。我正在按照此处给出的示例进行操作

Spring cloud GCP postgres example using service account

我的 application.properties 文件

    # Set to the Postgres user you want to connect to; 'postgres' is the default user.
spring.datasource.username=username
spring.datasource.password=password
spring.cloud.gcp.sql.database-name=tablename
# This value is formatted in the form: [gcp-project-id]:[region]:[instance-name]
spring.cloud.gcp.sql.instance-connection-name=project-id:region:instancename
# So app starts despite "table already exists" errors.
spring.datasource.continue-on-error=true
# Enforces database initialization
spring.datasource.initialization-mode=always
spring.cloud.gcp.project-id=project-id
spring.cloud.gcp.credentials.location=file:src/main/resources/key.json

我遇到了凭据错误

基于此link 我认为不是：

spring.cloud.gcp.credentials.location=file:src/main/resources/key.json

你应该使用：

spring.cloud.gcp.sql.credentials.location=file:src/main/resources/key.json
