Spring Boot default H2 jdbc connection (and H2 console)

This is how I got the H2 console working in spring-boot with H2. I am not sure if this is right but since no one else has offered a solution then I am going to suggest this is the best way to do it.

In my case, I chose a specific name for the database so that I would have something to enter when starting the H2 console (in this case, "AZ"). I think all of these are required though it seems like leaving out the spring.jpa.database-platform does not hurt anything.

In application.properties:

spring.datasource.url=jdbc:h2:mem:AZ;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect

In Application.java (or some configuration):

@Bean
public ServletRegistrationBean h2servletRegistration() {
    ServletRegistrationBean registration = new ServletRegistrationBean(new WebServlet());
    registration.addUrlMappings("/console/*");
    return registration;
}

Then you can access the H2 console at {server}/console/. Enter this as the JDBC URL: jdbc:h2:mem:AZ

As of Spring Boot 1.3.0.M3, the H2 console can be auto-configured.

The prerequisites are:

• You are developing a web app
• Spring Boot Dev Tools are enabled
• H2 is on the classpath

Even if you don't use Spring Boot Dev Tools, you can still auto-configure the console by setting spring.h2.console.enabled to true

Check out this part of the documentation for all the details.

Note that when configuring in this way the console is accessible at: http://localhost:8080/h2-console/
