Run the application by typing the following command on the terminal console at the project root directory.

In a production environment, you may like to package and run the Spring Boot application as a single jar file. The source code is available on Github. Let us understand the Oauth2. We will go one step further and add great integration tests! You will create a simple project with Spring Boot. You will learn to implement the basic CRUD methods. JUnit Tutorial for Beginners in 5 Steps. Setting up a basic JUnit example and understanding the basics of junit. For this, we need to have a database configuration first.

Spring boot provides a very convenient way to do so by adding a few properties in application. We will be using spring data JPA for our purpose. To save the uploaded file in the DB, we have a model class and we are using byte[] as a data type to save it in the DB.

Below is the REST implementation for this. The implementation is similar to above logic except it has a DB call to save the file instead of saving it to the local file system.
