H2 database has an embedded GUI console for browsing the contents of a database and running SQL queries. By default, the H2 console is not enabled in Spring. To enable it, we need to add the following property to application.properties: spring.h2.console.enabledtrue. If we're using YAML configuration, we need to add the property to application.yaml:

Before accessing the H2 database, we must enable it by using the following property. spring.h2.console.enabledtrue. Once we have enabled the H2 console, now we can access the H2 console in the browser by invoking the URL http://localhost:8082/h2-console. Note: Provide your port number in which your spring application is running. The following figure shows the console view of the H2 database. Example:

Learn to configure H2 database with Spring boot. H2 database is an in-memory database and is generally used for unit testing or POC purposes. Remember that an in-memory database is created/initialized when an application starts up; and destroyed when the application shuts down.

Introduction. Let's learn how to use the h2 database with the spring boot application and its configuration via application properties. H2 is an in-memory database that we can embed within the application. For this reason, H2 is the right candidate for loading test data or to prototype an application.

H2 Database Console. Frequently when developing Spring based applications, you will use the H2 in memory database during your development process. It's light, fast, and easy to use. It generally does a great job of emulating other RDBMs which you see more frequently for production use (ie, Oracle, MySQL, Postgres).

Let's consider a cenario when you want to do a quick proof of concept(POC) and using a traditional database involves a lot of overhead.

H2 is a relational database management system written in Java. It can be embedded in Java applications or run in client-server mode. The main features of H2 are: Very fast, open-source, JDBC API; Embedded and server modes; in-memory databases; Browser-based Console application; Small footprint: around 2.5 MB jar file size. Spring Boot CrudRepository

Thus, to work with H2 in Spring Boot, by default, you need to use the following connection parameters: spring.datasource.urljdbc:h2:mem:testdb spring.datasource.usernamesa spring.datasource.password In application.properties, you do not need to specify them - Spring Boot itself will raise the DATABASE with the default parameters (if H2 is present in the project). Explicitly, it makes sense to specify these properties only if you want to change the name of the database or place it on disk.

How to use H2 database in spring boot. Please follow the following steps to know how to use h2 database in spring boot 1)Please create a simple maven project. 2)Now please add following 3 maven dependencies in pom.xml which is shown below. Spring boot starter dependency org.springframework.boot spring-boot-starter-web Spring boot h2 database dependency

Like many developers I use H2 Database for building and testing Spring Boot apps. Using an In-Memory database for creating and destroying data with each build is efficient, but viewing the data while the application is running is problematic. Enter H2 Console.

This way, we're able to set the H2 database to use the in-memory approach by adding the mem parameter in the data source URL, followed by database name: spring.datasource.urljdbc:h2:mem:demodb. If we use the file-based persistence mode, we'll set one of the available options for disk locations instead of the mem parameter. In the next section, we'll discuss what these options are.

Spring Boot uses Hibernate for JPA implementation, we configure H2Dialect for H2 Database; spring.jpa.hibernate.ddl-auto is used for database initialization. We set the value to update value so that a table will be created in the database automatically corresponding to defined data model. Any change to the model will also trigger an update to ...

Using H2 in-memory DB for local development with Gradle The solution to the mentioned problem is to just use an in-memory database for local development. It's going to make your life so much easier. Let's see how we can configure Gradle to use H2, but only for local development.

Often when using Spring for enterprise application development, while developing code on your laptop, you will want to run against a in memory H2 database, and later you will deploy the code to a server and have it run against enterprise database such as Oracle. While Oracle is the #1 RDBMS used in the enterprise, it's a little heavy weight to use on a laptop.

Since we added H2 as a dependency, Spring Boot knows that in this project we will be connecting to the H2 database, so it auto-configures H2-related properties like the database URL, username, password, etc: If we look at the datasource.url property, the name of the schema is testdb and is an in-memory database (refered to as "mem").

Spring Boot can auto-configure embedded H2, HSQL, and Derby databases. You need not to provide any connection URLs. You need only include a build dependency on the embedded database that you want to use.

In this tutorial, we will show you how to use Spring Boot + Spring data JPA to save data into an H2 in-memory database and how to also query the data.
