Simple example: i have a page with header, footer and left menu. This modules viewing always. In header i am use dynamic information for count of users. I am create jspf files for header, for footer and left menu and include it to main page. I have Spring controllers and always need include to model variable for calculation of users. Maybe you know how it's do more grateful?
If you need to include a model among multiple controllers, then use a @ControllerAdvice with a @ModelAttribute method
@ControllerAdvice
public class GlobalDataAdvice {
@Autowired
private FooService fooService;
@ModelAttribute("foo")
Foo getFoo(){
return fooService.find(...);
}
}
I like SiteMesh for my layouts. It's pretty easy to use. http://wiki.sitemesh.org/wiki/display/sitemesh/Start+Using+SiteMesh+in+10+Minutes
You can also use JSP Tag Files. JSP tricks to make templating easier?
