How do I implement logout in a Spring Boot OAuth2 application?

To implement logout in a Spring Boot OAuth2 application, you can create a logout endpoint that invalidates the user's session.

What steps do I need to follow to create that logout endpoint?

First, you need to configure your security settings to allow for logout. Then, create a controller method that handles the logout request.

Can you show me an example of the controller method?

Sure! Here's a simple example:

@PostMapping("/logout")
public ResponseEntity<?> logout(HttpServletRequest request) {
    SecurityContextHolder.clearContext();
    return ResponseEntity.ok().build();
}

What about the frontend part? How do I trigger the logout?

You can trigger the logout by making a POST request to the logout endpoint when the user clicks a logout button.
