I came across HikariCP and I was amazed by the benchmarks and I wanted to try it instead of my default choice C3P0 and to my surprise I struggled to get the configurations right probably because the configurations differ based on what combination of tech stack you are using.

I have setup Spring Boot project with JPA, Web, Security starters (Using [Spring Initializer][1]) to use PostgreSQL as a database with HikariCP as connection pooling.
I have used Gradle as build tool and I would like to share what worked for me for the following assumptions:

1. Spring Boot Starter JPA (Web & Security - optional)
2. Gradle build tool
3. PostgreSQL running and setup with a database (i.e. schema, user, db)

This gist is related to SO post https://stackoverflow.com/questions/26490967/how-do-i-configure-hikaricp-in-my-spring-boot-app-in-my-application-properties-f

/**
 * Demonstrates how to use Grape to grab dependencies for
 * Groovy scripts.
 * 
 * Grape stands for the Groovy Adaptable (Advanced) Packaging Engine, and it is a part of the Groovy installation. 
 * Grape helps you download and cache external dependencies from within your script with a set of simple annotations.
 *
 * If, in your script, you require an external dependency, that you know is available in a public repository as Maven Central Repository,
