Interested in learning more about Thymeleaf? Check out my book Taming Thymeleaf. The book combines all of my Thymeleaf knowledge into an easy to follow step-by-step guide.

Thymeleaf 3.1.2 was released recently and is inluded in Spring Boot 3.0.10 and 3.1.3. For security reasons, it is no longer allowed for a Thymeleaf template to directly access org.springframework.web.servlet.support.ServletUriComponentsBuilder.

This was used in my Taming Thymeleaf book to build a generic fragment that can be used for pagination controls.

If you still use it, you get this exception while running the application:

Access is forbidden for type 'org.springframework.web.servlet.support.ServletUriComponentsBuilder' in this expression context.

The way to fix this is exposing the ServletUriComponentsBuilder as a Spring bean using @RequestScope:

    public ServletUriComponentsBuilder urlBuilder() {
        return ServletUriComponentsBuilder.fromCurrentRequest();

You can now replace urlBuilder.fromCurrentRequest() with @urlBuilder in the template itself.

To view the changes in context, check out this commit on GitHub.


Using Thymeleaf 3.1.2 needs a small change to the demo application of Taming Thymeleaf, but should be easy to apply given the above explanation.
