Spring Boot + IntelliJ + Embedded Database = Headache

Question

Either I\'m missing some core concept buried deep within some documentation (Spring, Spring Boot, H2, HSQLDB, Derby, IntelliJ) or I\'ve been staring at this for too long.

Answer 1

Using the example here to expose an in-memory DB via console and TCP I was able to connect using H2 Console and IntelliJ client as per screenshots.

Connect using IntelliJ - jdbc:h2:tcp://localhost:9092/mem:default

Connect using H2 Console: jdbc:h2:mem:default

Example application.yml

spring:
  application:
    name: example-service
  r2dbc:
    url: r2dbc:pool:h2:mem:///default?options=DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE
    username: testuser
    password: testpass
    pool:
      initial-size: 100
      max-size: 500
      max-idle-time: 30m
      validation-query: SELECT 1
