Question

我在Spring中有简单的doGet方法：

@Override
    public void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        HttpSession session = req.getSession(true);

        List<Category> categories = categoriesService.getCategories();
        req.setAttribute("categories", categories);

        if (!resp.isCommitted()) {
            req.getRequestDispatcher("thymeleaf_views/categories.html").forward(req, resp);
        }
    }

我可以获得HTML页面。但它的所有内容都没有得到解决（（

<body>
        <div>
            <h2>Categories</h2>
            <ul id="menu" style="list-style-type:none">
                <li th:each="category: ${categories}" th:text="${category.name}"></li>
            </ul>
        </div>
</body>

当我尝试加载页面时 - 它按原样加载标签 - 不会用标签替换标签（（可能是什么原因？

您必须设置TemplateResolver。 E. g。喜欢以下方式：

@Configuration
public class ThymeleafConfig {

@Bean 
public ServletContextTemplateResolver templateResolver() {
    ServletContextTemplateResolver resolver = new ServletContextTemplateResolver();
    resolver.setPrefix("/WEB-INF/jsp/");
    resolver.setSuffix(".html");
    resolver.setTemplateMode("HTML5");
    return resolver;
}

@Bean 
public SpringTemplateEngine templateEngine() {
    SpringTemplateEngine engine = new SpringTemplateEngine();
    engine.setTemplateResolver(templateResolver());
    return engine;
}

@Bean 
public ThymeleafViewResolver thymeleafViewResolver() {
    ThymeleafViewResolver resolver = new ThymeleafViewResolver();
    resolver.setTemplateEngine(templateEngine());
    return resolver;
}
}

将Spring与百日咳视图结合起来
