Spring MVC & Velocity: Template Structure

I would like to get such template functionality:

  • You have a template that defines the header, footer, and common parts of a full (x) html page.
  • When returning a String from @Controller it will determine the view included in a specific part of the template

Like this:

@Controller

 @RequestMapping(value = "/", method = RequestMethod.GET) public String home(Locale locale, Model model) { return "home_view"; }

view / home _view.vm

 <h2>Content title</h2> <p>Content text</p>

view /template.vm

 <html> <head> <title></title> </head> <body> <!-- Header of page --> #include({context variable which contains "home_view"} + ".vm"); <!-- Footer of page --> </body> </html>

If someone knows CakePHP, it looks like their template system

How can i do this?

Final decision based on @Nathan Bubna's suggestion .

The project is based on the Spring MVC pattern , with Maven controlled resources.
Spring version 3.1.1.RELEASE

I think Spring supports VelocityLayoutView. Or, I thought they did it.
