2 Hello Spring Security

This chapter covers

Creating your first project with Spring Security
Designing simple functionalities that use the basic actors for authentication and authorization
Understanding the relationship between the main actors involved in the basic authentication process
Applying the basic contracts to understand how these actors relate to each other
Writing your implementations for the primary responsibilities
Overriding the Spring Boot’s default configurations

Spring Boot appeared as an evolutionary stage for application development with the Spring framework. Instead of you needing to write all the configurations, Spring Boot comes with something preconfigured, so you override only the configurations that don’t match your implementation. We also call this approach “convention-over-configuration”.
