我想使用 Spring Boot 创建 Web 服务,将其添加到 docker 映像,连接到云 sql,然后在 Compute Engine 上运行。
我正在使用 docker compose 来组合项目的图像和云 sql 代理图像。但是,无论我给它什么 jdbc URL 都无法连接。现在,我正在本地尝试所有这些
我试过以下网址:
1. spring.datasource.url=jdbc:mysql:///cloudsql/myinstancename/${MYSQL_DATABASE}
2. spring.datasource.url=jdbc:mysql://cloudsql/myinstancename/${MYSQL_DATABASE}
3. spring.datasource.url=jdbc:mysql://127.0.0.1:3306/${MYSQL_DATABASE}
