Kotlin – Spring Security Customize Logout Success Handler

In the tutorial, we will show you how to customize Logout Success Handler with Kotlin Spring Security web application.

I. Technologies

We use LogoutSuccessHandler to customize a behaviour of Kotlin Spring Security after logout successfully. In the tutorial, it will redirect to logoutsuccessful.html page:

    xmlns:th="http://www.thymeleaf.org"
    xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity3">

                style="border: 1px ridge #003312; padding:20px; float: none; margin: 0 auto;">
            <h1>Logout Successfully!</h1>
