# Understanding spring security By example

* [Understanding spring security By example](#understanding-spring-security-by-example)

  * [Learning](#learning-)

  * [Data Setup](#data-setup-)

## Learning 

1. By default, when we add spring security to our project,

    It adds a user with username as `user` and password would be printed as **default password**  in console when application starts

   **Note**: to see the default password on console you need to set log level in application.yaml 

   for below spring package`logging.level.org.springframework.security: INFO`

2. Add username and password to `application.yml` and add `.httpBasic(Customizer.withDefaults())` in `SecurityFilterChain` bean. 

   With this change you will be able to `login` with `username/password` provided in `application.yml`

3. Added `oAuth2 client` support with `Keycloak` using reference [here](https://developers.redhat.com/articles/2023/07/24/how-integrate-spring-boot-3-spring-security-and-keycloak)

4. Added `Jwt based authentication`g for `/greet` api present in Postman collection using `KeyCloak` as resource server used reference [here](https://www.baeldung.com/spring-boot-keycloak)

## Data Setup 

1. Import realm in `/setup` folder in keycloak

2. Create user in realm imported in step-1
