Multi-language pages

[ee722]

Hi,

I have a site which supports two languages German and Japanese. The controller for the home page is like this:

@Controller
@RequestMapping({"/home-de.html", "/home-jp.html"})
public class HomeController {
	@RequestMapping(method=RequestMethod.GET)
	public String home(Model model) {
		...
	}	
}

The locale is controlled by request urls by checking whether they end with "-de.html" or "-jp.html". Everything works fine.

If the site is expanded to support more languages, the value of the RequestMapping would increase (i.e. the length of the array). My question is how to dispatch all incoming urls home-de.html, home-jp.html, home-nl.html, home-... to the same controller HomeController, where HomeController would be

@Controller
@RequestMapping("/home.html")
public class HomeController {
	@RequestMapping(method=RequestMethod.GET)
	public String home(Model model) {
		...
	}	
}

I tried to use a custom HandlerMapping but failed.

Thank you!

Take an incoming request url .../home-jp.html for example, I want to change it to .../home.html before Spring DispatcherServlet servlet redirects it. In other words, when .../home-jp.html comes in, I'd like DispatcherServlet servlet redirects .../home.html instead of .../home-jp.html. Does anyone have an idea where I can perform that modification?

Thank you!

After doing more research on the topic, I think I need to create a custom HandlerMapping class for it. Does anyone know which method I should override?

By the way, I think the topic is very common in multiple-language web sites. How do you handle the situation without using locale/language parameter in the urls?

Thank you!

Why not simply use URL Rewriting?! There are good filters out there (or if you use apache httpd is supported in there also) so that you can simply change the internal url (and transform home-jp.html into home.html?locale=jp for instance). You could always create your own filter which wraps the request and does the munging for you but I propably would use URL Rewriting.

Thank you for the suggestion.

When I write my own filter, I don't know which object I should use to re-set incoming URLs? I can retrieve them via HttpServletRequest but the ServletRequest doesn't have a seter for the request URLs.

Thank you!

You don't reset incoming urls you wrap the request... But why reinvent the wheel? There is already a pretty good URL Rewriting filter out there, why not use that?
