H2 Web Console to In Memory Database – Spring Boot

To get an H2 Database Web Console accessing an in-memory database running on Spring Boot:

1. Register H2’s WebServlet (with UrlMapping /console/*) to your Spring project in a Configuration annotated class. Restart your Application.
2. Open a web page to http://localhost:8080/console/
3. Be sure you’re accessing the correct database JDBC URL (default would be jdbc:h2:mem:testdb)
