Spring MVC &速度:模板结构 [英] Spring MVC & Velocity : Template structure
本文介绍了Spring MVC &速度:模板结构的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想实现这种模板功能:
I'd like to achieve this kind of template functionality:
- 具有定义完整 (x)html 网页的页眉、页脚和公共部分的模板
- 当从
@Controller返回 String 时，它将定义包含到模板特定部分的视图
- Have a template defining header, footer, and common parts of complete (x)html webpage
- When returning String from
@Controllerit will define the view included to specific part of template
像这样:
@Controller
@RequestMapping(value = "/", method = RequestMethod.GET)
public String home(Locale locale, Model model) {
return "home_view";
}
views/home_view.vm
<h2>Content title</h2>
<p>Content text</p>
views/template.vm
<html>
<head>
<title></title>
</head>
<body>
<!-- Header of page -->
#include({context variable which contains "home_view"} + ".vm");
<!-- Footer of page -->
</body>
</html>
如果有人知道 CakePHP，这类似于它的模板系统
我该怎么做?
