Authentication and authorization in Spring Boot

We have already discussed the concepts of Spring Security in the previous section; now, we will learn how to integrate Spring Security into our Spring Boot application. As we move on to the examples, we will be using all the modules and features of Spring Boot Security.

Authentication and authorization are the most common concepts that we come across when we implement security in our applications. These are the two validations we apply for our application to be secure.

Configuring Spring Boot and implementing authentication

We will first implement authentication in our application. We first need to add the Spring Boot Security dependency to our project. To add the dependency, we will add the following to pom.xml:

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-security</artifactId>
</dependency>
