Each time the program is run, a new database is created, starting with fresh tables and data.ĭatabase-platform is actually unnecessary. create-drop: like create, but also drops the schema when the session closes (useful for testing).create: creates the schema, destroying any previous data.validate: validates the schema but makes no changes.The ddl-auto property specifies hibernate’s behavior upon loading. Spring : jpa : hibernate : ddl-auto : create database-platform : datasource : url : " jdbc:postgresql://localhost:5432/springbootjpa" username : jpatutorial password : You should be able to run the following command: psql -V and get a response like: For this, you can use the Postgres CLI, psql. The next thing you’ll need to do is create a Postgres user and database for the project.

If you don’t already have it installed, go to their downloads page and install it. You’ll need to have PostgreSQL installed for this tutorial. For example, in this tutorial, you’ll be using Postgres, but later if you decided you’d rather use MySQL, all you’d have to do is change out some dependencies. No need to actually write persistence or retrieval methods! Another great benefit is that you can change the underlying database implementation transparently without having to change any code.
As you’ll see, it makes persisting your Java classes as simple as adding some annotations and creating a simple repository interface. Spring Data JPA is a wrapper around JPA providers such as Hibernate. It describes an abstraction layer between Java classes and a relational database. JPA is the Java Persistence API, a specification for managing relational databases using Java. If this sounds complicated - don’t worry! It’s not.īefore we dig in, let’s cover some background:Ī resource server is a programmatic access point for your server’s functions and data (basically the same as an API server and/or possibly REST server). On top of that, you’re going to implement a group-based authentication and authorization layer using OAuth 2.0. In this post, you’re going to build a resource server using Spring Boot and Spring Data JPA. When coupled with Okta, you get professionally maintained OAuth and JWT technologies easily integrated into Spring Boot using Spring Security. Within the Java ecosystem, Spring makes building secure resource servers for your data simple. Java is a great language with decades of history in professional, enterprise development, and is a great choice for any application’s server stack.

Every non-trivial application needs a way to save and update data: a resource server that is accessible via HTTP.
