Spring Boot and OAuth2

Examples of single page apps:

• simple - a very basic static app with just a home page and unconditional login Spring Boot’s OAuth 2.0 configuration properties
• click - adds a link that the user has to click to login
• logout - adds a logout link as well for authenticated users
• two-providers - adds a second login provider so the user can choose on the home page which one to use
• custom-error - adds an error message for unauthenticated users, and a custom authentication based on GitHub’s API

  Each app can be imported into an IDE, and can run the main method in SocialApplication to start an app. They all come up with a home page on http://localhost:8080.

  Can run all the apps on the command line using mvn spring-boot:run or by building the jar file and running it with mvn package and java -jar target/*.jar.

  Creating a New Project:

• create a Spring Boot application by go to https://start.spring.io and generate an empty project
• put these commands into the command line: mkdir ui , cd ui curl https://start.spring.io/starter.tgz -d style=web -d name=simple | tar -xzvf -
• Add a home page - create a index.html

• Securing the application with GitHub and Spring Security To make the application secure, you can simply add Spring Security as a dependency. org.springframework.boot spring-boot-starter-oauth2-client

• Add a New GitHub app
