Erreur Google Cloud SQL: nom d'hôte inconnu

Question

J'essaie de suivre le didacticiel suivant pour essayer d'exécuter l'application Spring Petclinic sur google app engine. Les actions décrites dans le tuorial sont en cours sur le shell nuage google:

https://cloud.google.com/community/tutorials/run-spring-petclinic-on-app-engine-cloudsql

à l'étape 7:

./mvnw -Drun.profiles=mysql spring-boot:run 

mais je INTRODUISE l'erreur suivante

Answer 1

que je rencontrais le EXACT même question. Heureusement, j'ai été capable de comprendre grâce à l'un des commentaires sur le fil du tutoriel.

Cette ligne à l'étape 5 du tutoriel est incorrect:

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

Au lieu de cela, vous devez avoir:

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

Il est vraiment regrettable. J'espère avoir aidé.
