Flyway integration with spring boot doesn't execute migration scripts on embedded H2 database

Question

I am trying to make migration demo on embedded H2 data base in Spring Boot application using Flyway.

application.properties

logging.level.org.org.springframework=DEBUG
server.port=8181
spring.h2.console.enabled=true
spring.h2.console.path=/h2
spring.datasource.url=jdbc:h2:mem:testdb
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driver-class-name=org.h2.Driver
spring.flyway.baseline-on-migrate=true
spring.jpa.hibernate.ddl-auto=none

migration-script(V2__create_shipwreck.sql) under db/migration

CREATE TABLE SHIPWRECK(ID INT AUTO_INCREMENT,
    NAME VARCHAR(255),
    DESCRIPTION VARCHAR(2000),
    CONDITION VARCHAR(255),
    DEPTH INT,
    LATITUDE DOUBLE,
    LANGITUDE DOUBLE,
    YEARS_DISCOERED INT);

console log

H2 database tables UI

After starting the Spring Boot application, the table has not been created, so what's the problem here?

Answer 1

I had the same issue, it was solved after making the change to application.properties as datasource.url to file instead of mem

able to create table with details Correct: spring.datasource.url=jdbc:h2:file:~/dasboot

application.properties

logging.level.org.org.springframework=DEBUG
server.port=8080

spring.h2.console.enabled=true
spring.h2.console.path=/h2

spring.datasource.url=jdbc:h2:file:~/dasboot
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driver-class-name=org.h2.Driver

spring.flyway.baseline-on-migrate=true
spring.jpa.hibernate.ddl-auto=none
