找不到模板StringTemplate

Question

我正试图在谷歌应用引擎中创建一个wiki应用程序。我正在使用字符串模板。但我不明白模板文件的层次结构。

这是密码。

• 必需的导入完成。

公共类添加扩展HttpServlet{受保护的HttpServlet doPost(HttpServletRequest req，HttpServletResponse resp)抛出ServletException，IOException { // TODO自动生成的方法存根//super.doPost(req，resp)；DatastoreService datastoreService =req.getParameter字符串标题=req.getParameter(“标题”)；实体articleEntity =新实体(“条款”，规范化(标题))；articleEntity.setProperty(“标题”，标题)；UserService userService = UserServiceFactory.getUserService()；用户用户= userService.getCurrentUser()；if(user != null){ String作者= user.getNickname()；ArticleEntity.setProperty(“作者”，作者)；}articleEntity.setProperty(“作者”，作者)；} String content = req.getParameter("content")；myContent =新文本(内容)；articleEntity.setProperty(“内容”，myContent)；datastoreService.put(articleEntity)；resp.sendRedirect("index.jsp")；}私有字符串规范化( String trimmedLower = str.toLowerCase().trim()；字符串urlReady = trimmedLower.replace(“"，"-")；返回urlReady；}

这是目录结构。
