Spring Boot PostGre DataBase Setup

I tested to use a cloud Postgres database provided by Heroku from my Netbeans in the following database connection setup. However, it led to a connection failure.

I think the fault should be at the JDBC URL, which needs extra string to break down the https. Please ref. to how-to-connect-postgres-database
