如何从httpServletResponse writer获得百里香th：text？

Question

我写了这个测试方法：

@GetMapping("recipe/random")
public void getRandom( HttpServletResponse response) throws IOException {
    String random = String.valueOf(new Random().nextInt());
    response.setContentType("text/html;charset=UTF-8");
    PrintWriter writer =response.getWriter();
    writer.println(random);
    writer.close();
}

如何使用百里香叶将其嵌入标签？

类似：

<h1 class="text" th:href="@{/recipe/random}">hello</h1>
