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

To add to what heenenee mentioned above. If you dont specify AUTO_SERVER only one connection will be permitted to your H2 instance.

I am using spring-boot with spring-data-jpa. Make sure you have @Entity declared for your entities that represent each table(s).

Following is my application.yml / application.properties

spring.datasource.url: 
jdbc:h2:file:/Users/blah[![enter image description here][1]][1]/db/vlad4;AUTO_SERVER=TRUE
spring.datasource.username: sa
spring.datasource.password:

spring:
  jpa:
    hibernate:
      ddl-auto: create #will create schema based on entities
    show-sql: true

Start your application and import some data into it. Spring boot will automatically import your data if you have import.sql in the classpath ex: /src/main/resources/import.sql

Configure you IntelliJ like so

If you are not using IntelliJ download the server/client combo @ http://www.h2database.com/html/download.html extract it and start the browser-based client using:

h2/bin: java -cp h2*.jar org.h2.tools.Server

Connect to your imbedded database by specifying the connection string:
