Because it is an embedded in-memory database, it makes your build portable. H2 is written in Java and is easily runs as an embedded in-memory database. The H2 database is a popular database to use when developing Spring applications. Click here to learn about my Spring Framework 5: Beginner to Guru online course! H2 Database It also sets you up for being able to automate integration and functional tests with a continuous build server such as Jenkins. The advantage of doing this for you as the developer is youвЂ™re working against known data while you are doing your development. With the speed of modern computers, even a complex set of tables and data is going to load in just a few seconds. And it does not add very much to your startup time. It sounds like a lot of work, but itвЂ™s really not much. What we are going to do in this tutorial is set up an in-memory database, configure a JPA entity, setup Hibernate to automatically create the database tables, and on startup add data to the database for our use and testing.Д«y doing this, each time we start our application, we have a newly created database, with known data populated into the database tables. With Spring managing the dependency injection for us, it makes swapping databases in and out very easy. So, itвЂ™s easy to plug in a different persistence implementation. The persistence API in Java follows the InterfaceВ Segregation design principle of object-oriented design. ItвЂ™s a great database, but itвЂ™s not really meant to run from a laptop. Oracle is a great database, but itвЂ™s also BIG and resource intensive. When developing Spring applications, it is very common to use an in-memory database for your development, and then a real database installation for your testing and production environments. When changing databases with complex mappings, youвЂ™re going to hit minor edge cases here and there.

The JPA mapping code you use on your domain POJOs doesnвЂ™t change. If you want to change from Oracle to DB2 or to MySQL, it is just a matter of changing the database drivers. Hibernate / JPA does a great job of abstracting the persistence layer. If youвЂ™re doing enterprise application development with the Spring Framework, youвЂ™re probably going to be using a relational database. While all the interest in the media is around No-SQL databases, relational databases are time proven workhorses. Like other things in Spring Boot, these are enabled by simply having the dependency on your classpath. Spring Boot comes with pre-configured options for relational databases. We will use these tools to persist data to the database in our Spring Boot Web Application. In this part of my Spring Boot tutorial series, weвЂ™ll set up the H2 database and Spring Data JPA.
