How to connect to a Google Cloud SQL database using Java

Question

I am in the process of making my database cloud based, however I'm having trouble connecting to it. I have followed this

https://cloud.google.com/sql/docs/mysql/connect-app-engine-standard#java

I think the problem is I am having problems setting up HikariCP in my Java project. As I keep getting the error:

java.lang.NoClassDefFoundError: Could not initialize class com.zaxxer.hikari.HikariConfig

So if anyone has any solutions, either fixing the problem above, or a new way about it I would be very grateful.

Answer 1

Based on the github for Java or the MySQL/Postgres JDBC and R2DBC drivers which allows the user with proper permission to connect to a Cloud SQL database.
