Answer 1

を高く評価しています。 幸いにも、私はチュートリアルのスレッドのコメントの1つのおかげでそれを理解することができました。チュートリアルのステップ5に

この行が正しくありません：

spring.datasource.url=jdbc:mysql://google/petclinic?cloudSqlInstance=INSTANCE_CONNECTION_NAME=com.google.cloud.sql.mysql.SocketFactory 

代わりに、あなたは持っている必要があります。

spring.datasource.url=jdbc:mysql://google/petclinic?cloudSqlInstance=INSTANCE_CONNECTION_NAME&socketFactory=com.google.cloud.sql.mysql.SocketFactory 

それは本当に残念です。助けてくれることを願っています。
