google-app-engine - 无法使用 spring cloud gcp starter 将 Spring Boot 与 Cloud SQL 连接

转载作者：行者123 更新时间：2023-12-04 15:57:45

Spring Boot 新手试图使用第二代 Cloud SQL (mysql) 将我的应用程序托管在 GCP AppEngine Flexible 上。

使用我从这里获得的 Spring Cloud GCP 启动器:
https://github.com/spring-cloud/spring-cloud-gcp/tree/master/spring-cloud-gcp-samples/spring-cloud-gcp-sql-sample ，我正在尝试让我的本地 Spring Boot 应用程序连接到 Cloud SQL。尝试在本地 Tomcat 上运行 SQLApplication 时，我得到:

我对这个项目所做的唯一更改是 application.properties。我也使用 gcloud 进行了身份验证。

这是我的 application.properties，不起作用:

spring.cloud.gcp.sql.database-name=sqldemo
spring.cloud.gcp.sql.instance-connection-name=Project:Region:Instance
spring.datasource.continue-on-error=true
spring.datasource.initialization-mode=always
spring.datasource.username=myuser
spring.datasource.password=mypass

我已经尝试将 mysql 套接字工厂直接添加到 pom.xml，但没有奏效:

<dependency>
    <groupId>com.google.cloud.sql</groupId>
    <artifactId>mysql-socket-factory</artifactId>
    <version>1.0.10</version>
</dependency>

我已经确保我的 SQL API 已启用。
谢谢!

spring.datasource.continue-on-error=true

# Leave empty for root, uncomment and fill out if you specified a user
spring.datasource.username=root

## Uncomment if root password is specified
spring.datasource.password=root

server.port = 80

我已经使用 gcloud 进行了身份验证。
我正在使用 spring-boot:run 运行此示例
