Answer 1

It's quite easy to accomplish this, thanks to a hint from Balaji Krishnan.

Basically, I had to add the Thymeleaf Spring Security integration module to my build.gradle file as follows:

compile("org.thymeleaf.extras:thymeleaf-extras-springsecurity3")

Then in my template I just used the following markup:

<span th:text ="${#authentication.getPrincipal().getUser().getFirstName()}"></span>

Answer 2

When using Spring boot 2.2.1.

For the maven, Add these lines to the pom.xml

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

In the thymeleaf

<span th:text="${#authentication.getPrincipal().getUsername()}"></span> <span th:text="${#authentication.getPrincipal().authorities}"></span>

Answer 3

For thymleaf 4 and above you have to modify some classes in order to get the info. Heres how you can do that:

First, add the getter of your user getUser(){return this.user;} in the UserDetails class and then push that object in the UserDetailsService object. Without these changes, thymleaf will not parse your HTML file.

Then you can get the info as follows:

<span sec:authentication="principal.user.name">
