CODE EXAMPLE FOR SQL

Caused by: java.lang.RuntimeException: Unable to obtain credentials to communicate with the Cloud SQL API

This error comes if "application_default_credentials.json" file is not there in "C:Users<USER_NAME>AppDataRoaminggcloud"

To populate this JSON file, run below command in cmd prompt;

command : gcloud auth application-default login

So this will create "application_default_credentials.json" file in the above directory. Now, you can restart your spring boot application.
