thymeleaf sec:authorize not working in spring boot

Question

I have a Spring MVC project with Thymeleaf and in memory authentication. In my html I want to display the current user that is logged in and diplay the logout button only when somebody is logged in.

Here is a simple html that should display the username, but is always displays Bob and a text that should only be displayed when somebody is logged in, but it's always displayed.

Any idea what I'm doing wrong?

Here is my pom.xml

Answer 1

I updated my thymeleaf security to springsecurity5 and now it is working

<dependency>
    <groupId>org.thymeleaf.extras</groupId>
    <artifactId>thymeleaf-extras-springsecurity5</artifactId>
</dependency>

Answer 2

I've had similar problem, my implementation 'org.thymeleaf.extras:thymeleaf-extras-springsecurity5' was missing from build.gradle altogether.
