</bean>webapp>>WEB-INF>>api下面所有的html改成.ftl,Freemarker语法和jstl差不多,html照常写在*.ftl中,Controller调用代码如下
@RequestMapping(value = "/index", method = RequestMethod.GET)
public String frame_article(Model model){
model.addAttribute("fm","666");
return "api/index";
}<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
${fm}
</body>
</html>
