NoSuchRendererException：找不到名为 'freemarker' 的渲染器

Question

我正在尝试制作一个同时使用 Tiles、Spring 和 FreeMarker 的应用程序。我的项目只使用 Tiles 和 Spring，但是当我尝试在我的 Tiles 模板中使用 ftl 文件时，出现错误

这是我的磁贴模板的样子

<!DOCTYPE tiles-definitions PUBLIC
      "-//Apache Software Foundation//DTD Tiles Configuration 3.0//EN" 
      "http://tiles.apache.org/dtds/tiles-config_3_0.dtd">

<tiles-definitions>

    <!-- Default Main Template -->
    <definition name=".mainTemplate" template="/templates_ftl/main.ftl" templateType="freemarker">
        <put-attribute name="title" value="Permissions Editor" type="string" />
        <put-attribute name="footer" value="/templates_ftl/footer.ftl" type="freemarker" />
        <put-attribute name="body" value="/templates_ftl/blank.ftl" type="freemarker" />
    </definition>

    <definition name="login" extends=".mainTemplate">
    </definition>
</tiles-definitions>

这只是我正在努力让 FreeMarker 工作的一个小例子，这样我就可以在我的项目的其余部分中使用它。这是控制器。

    @RequestMapping(value = "/")
    public String login(@ModelAttribute("LoginInfo") LoginInfo info, HttpServletRequest request) {
        logger.info("First visit to login page");

        if (HttpUtility.getInstance().compareSession(request)) {
            logger.info("Leaving initial login page with user already logged in, sending to show_roles page");
            return "show_roles";
        }
        logger.info("Leaving initial login page sending to login submit");
        return "login";
    }

我通过添加

解决了它

<#assign tiles=JspTaglibs["http://tiles.apache.org/tags-tiles"]>

到我的 ftl 文件的顶部

NoSuchRendererException：找不到名为 'freemarker' 的渲染器
