I would like to manage the authorizations on my rest API coded in java via the spring boot framework using the most recent spring keycloak libraries but I don't know which ones to use and how to code the configuration.

I tried the spring security adapter keycloak library but this one seems outdated depending on the IDE I use

We have to use official/recommended OAuth2 implementation from Spring, wrapped and provided via Spring Boot Starter if you are using Spring Boot 3.x and Keycloak.

For bearer token based REST APIs:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-oauth2-resource-server</artifactId>
</dependency>

For Spring based UIs:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-oauth2-client</artifactId>
</dependency>
