将 Spring 连接到 Google Cloud SQL 时出错
Error when connecting Spring with Google Cloud SQL
我尝试使用我的 Google 云 SQL 实例配置我的 Spring 引导应用程序（部署在 App Engine 上）两天。但是没用。
我目前的项目配置是这样的:
pom.xml
注意：Mysql 连接器 java 的版本为 5.1.45。所以我使用 mysql-socket-factory.

感谢所有帮助过我的人:)
我认为 Hibernate 无法自己找出方言选项。
在doc中指定，如果不指定，则委托Hibernate自动检测方言，即org.hibernate.dialect.H2Dialect。
但对于 mysql-socket-factory，您有更多选择。所以你需要明确指定它，比如spring.jpa.properties.hibernate.dialect: org.hibernate.dialect.MySQL5Dialect
让我们知道它是否有效。
