>>加载模板错(TEMPLATE_LOAD_ERROR): webapp 配置 ?400报错

模板跟目录我看你是“WebContent\” 这个应该是绝对路径才对。你的开发环境是什么啊，用的是什么web框架，还有，你的配置文件怎么设置的

你可以直接调用api设置Web模板根目录:

WebAppResourceLoader loader = (WebAppResourceLoader)groupTemplate.getResourceLoader();
loader.setRoot("绝对路径地址")

Configuration cfg = null;
        try {
            cfg = Configuration.defaultConfiguration();
        } catch (IOException e) {e.printStackTrace();}
        WebAppResourceLoader resourceLoader = new WebAppResourceLoader();
        resourceLoader.setRoot("WebContent");
        GroupTemplate groupTemplate = new GroupTemplate(resourceLoader, cfg);
        Template t = groupTemplate.getTemplate("a.html");
        System.out.println("="+ t.render());

这是代码，  @闲.大赋

resourceLoader.setRoot("\home\beetl\WEB-INF\template");

另外，与servle集成 只要引用 ServletGroupTemplate(https://github.com/javamonkey/beetl2.0/blob/master/beetl-core/src/main/java/org/beetl/ext/servlet/ServletGroupTemplate.java)，他默认使用的跟目录就是WebRoot 目录+配置文件配置的相对于WebRoot的目录，因此，如果你的模板位于WEB-INF\template, 则只需要使用ServletGroupTemplate，并且，配置文件RESOURCE.root=/WEB-INF/template.
