2 Hello, Spring Security

 

This chapter covers

  • Creating your first project with Spring Security
  • Designing simple functionalities using the basic components for authentication and authorization
  • The underlying concept and how to use it in a given project
  • Applying the basic contracts and understanding how they are correlated
  • Writing custom implementations for primary responsibilities
  • Overriding Spring Boot’s default configurations for Spring Security

Spring Boot appeared as an evolutionary stage for application development with the Spring Framework. Replacing the need to write all the configurations, Spring Boot comes with some preconfigured, so you can override only the configurations that don’t match your implementations. We also call this approach convention-over-configuration. Spring Boot is no longer a new concept, and today, we enjoy writing applications using its third version.
