As of my knowledge cutoff date of September 2021, there was no Spring Boot 3.0 release
yet. However, I can guide you on how to generate a Spring Boot 2.5 project which implements a REST API using OAuth2 security. To generate a Spring Boot project, you can use the Spring Intializr. Follow the steps below:
1. Go to the Spring Initializr website at https:/start.spring.
2. Select your desired Spring Boot version (e.g. 2.5.x) and language (e.g. Java or Kotlin)
3. Fillin the project metadata such as group name, artifact name, and package name
4. Select the dependencies that you need. For this project, select Spring Web, Spring Security, and Spring Data JPA.
5. Click on the "Generate" button to download a ZIP file of the generated project.
Once you have generated the project, you can add the necessary configuration for OAuth2 security. Here are the high-level steps:
1. Add the necessary dependencies for OAuth2 support. In your “pom.xml” file, add the following
2. Configure your application to use OAuth2 security. You can do this by creating a WebSecuriyConfigurerAdapter and overriding the “configure” method to enable OAuth2 security.
