Production-ready Spring Boot, crafted carefully.

• Oct 19, 2023 Taming Thymeleaf update for Thymeleaf 3.1.2 spring-bootthymeleafalpine 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: org.springframework.expression.EvaluationException: Access is forbidden for type 'org.springframework.web.servlet.support.ServletUriComponentsBuilder' in this expression context.

• Feb 20, 2023 Toasts notifications in Thymeleaf with Shoelace and htmx spring-bootthymeleafhtmx I recently played around with Shoelace, a library of web components. The nice thing about web components is that they are framework agnostic, so we can use them with Thymeleaf as well. This blog post will show how to use the Alert Toast component to show a confirmation or an error to the user. See also part 2 for a similar demo where the HTML of the notifications is generated in Thymeleaf instead of in JavaScript.
