Unable to instantiate H2 - spring-boot

Question

I am trying to setup H2 as in-memory database. I have configured it as :
spring:
profiles: qa
datasource:
#url: jdbc:h2:mem:testdb;MODE=MySQL;DB_CLOSE_ON_EXIT=FALSE;INIT=CREATE SCHEMA IF NOT EXISTS "public"
jdbc-url: jdbc:mysql://localhost:3306/lisdashboard
username: '#lisdashboard.db.username#'
password: '#lisdashboard.db.password#'
h2:
console:
path: /admin/h2-console
However I am getting this error when I try to run it
- Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'flywayInitializer' defined in class path resource [org/springframework/boot/autoconfigure/flyway/FlywayAutoConfiguration$FlywayConfiguration.class]: Invocation of init method failed; nested exception is java.lang.RuntimeException: Driver org.h2.Driver claims to not accept jdbcUrl, jdbc:mysql://localhost:3306/lisdashboard

I am not sure why it doesn't accept the jdbc url, Is there any issue in the format of my confg?

Answer 1

You are using a MySQL jdbc url to try to connect to an H2 instance.
You need to replace your configuration to use the url jdbc:h2:mem: instead of the one you are using now jdbc:mysql://localhost:3306/lisdashboard.
If you want to use a different type of H2 instance, check the documentation to see the alternatives (such a file instance).

Answer 2

If you want to use H2 your config should look like:
spring:
profiles: qa
datasource:
url: jdbc:h2:mem:testdb;MODE=MySQL;DB_CLOSE_ON_EXIT=FALSE;INIT=CREATE SCHEMA IF NOT EXISTS "public"
username: '#lisdashboard.db.username#'
password: '#lisdashboard.db.password#'
h2:
console:
path: /admin/h2-console
You had a # infront of the URL and # is a comment in YAML
