Integrate an H2 Database in Your Spring Boot App

In this tutorial, we will be integrating the H2 database in your Spring Boot application. Note that the H2 database is in the embedded mode.

You have created a Spring Boot application and would like to integrate with an H2 database.

In pom.xml, add the below dependency:

 <!-- H2 Database -->
 <dependency>
 <groupId>com.h2database</groupId>
 <artifactId>h2</artifactId>
 </dependency>

In the application.properties file, add the below line to enable the H2 database:

# H2
spring.h2.console.enabled=true
spring.h2.console.path=/h2

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

Take a Maven build and run the application as a Spring Boot app.

Open a browser and type http://localhost:8080/h2 to get the below image.
