Spring Boot will automatically pick up this file and run it against an embedded in-memory database, such as our configured H2 instance. This is a good way to seed the database for testing or initialization purposes. We can disable this default behavior by setting the spring.sql.init.mode property to never.

Step 1: Adding the dependency. To use the H2 database in the spring boot application we have to add the following dependency in the pom.xml file: dependency> com.h2database h2 runtime . Step 2: Write some properties in the application.properties file.

In the spring.datasource.url property, mem is the name of an in-memory database and testdb is the name of schema that H2 provides, by default. We can also define our own schema and database. The default username is sa and the blank password denotes an empty password. If we want to change the username and password, we can override these values.

Unlike the h2 database, Spring Boot doesn't support any web-based console for Derby. Initializing Schema. All embedded databases would require initializing Schema. This is because the embedded databases are not persistent and would lose data on restart. To achieve this, Spring Boot expects a schema.sql and data.sql file in the classpath.

only application.properties in the root or config directory or taken into account (by default). (See the reference guide). The fix is to simply move your application.properties to src\main\resources. a / is missing before spring.h2.console.path it have to look like : spring.h2.console.path/h2

Make sure to edit your application.properties and change the database information to reflect where you would like H2 to create the DB file.
