Spring Boot / Thymeleaf: Fragments via Ajax
This is probably not the best approach and you guys can feel free to correct me in the comments section, but here is a simple tutorial on how I’m getting my fragments loaded via ajax. Same as before, the full project is on my Github: https://github.com/mtrojahn/spring-thymeleaf-fragments-from-ajax Let’s get to it: MyController.groovy

@Controller class MyController { @GetMapping(['/', '/index.html']) def index(Model model) { 'index' } @GetMapping('/frag1') def frag1(Model model) { model.addAttribute("content", "hello") "fragments/frag1 :: content" } @GetMapping('/frag2') def frag2(Model model) { model.addAttribute("content", "world") "fragments/frag2 :: content" } } |
Very simple controller. Nothing special except for the fact it’s returning Thymeleaf fragmets from /resources/templates/fragments. As you probably noticed, for the sake of this example, each fragment is recieving it’s “content” from the controller. Here’s a fragment: frag1.html

<th:block th:fragment="content" xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org"> <div th:text="${content}"></div> </th:block> |
Now the index.html

Each button has it’s event and is calling...
