# Getting Started

Project shows the use of question mark in sql while working with postgres and jsonb.

Project uses Java 17, Spring Boot 2.6.0, test containers and gradle wrapper.

You can find 3 repository implementations in different profiles, jpa, jdbc and data jpa.
JDBC uses ?? and jpa \\?\\?. It works but data jpa does not work.

./gradlew clean build or run tests in IDE

Actual output:
