@RequestParam doesn't seem to be decoded

[sgunter]

Hi all

I'm having a problem with a @RequestParam that gets passed in via querystring, and was hoping someone could point me in the right direction. The method signature looks like this:

@RequestMapping(value="/view.html", method=RequestMethod.GET)
	public String viewUser(@RequestParam("username") String username, Model model) {
...
}

From what I can see in the Spring docs, DispatcherServlet enables the DefaultAnnotationHandlerMapping which decodes the servlet path (see http://static.springsource.org/sprin...handlermapping). Does this also automatically decode @RequestParam values before passing them to the handler method ("viewUser" in this case).

To be more specific, I'm passing the username in the querystring - but the username may contain characters like ü (encoded as %FC in the URL).

So my question is: How do I get this value provided in its decoded form?

Thanks very much

EDIT: I'm using v3.0.3 - just in case that question arises.

EDIT2: I've also configured the CharacterEncodingFilter to use UTF-8 in web.xml

Anyone have any suggestions for this?

I think I have the same problem here, when I tried to display ${param.my_param_name} in my jspx, the param_value was not decoded correctly. I already use CharacterEncodingFilter but it seems not work on my case.

<jsp:scriptlet>
	//print out UTF-8
	System.out.println(request.getCharacterEncoding());
	//wrong value
	System.out.println(request.getParameter("my_param_name"));
</jsp:scriptlet>

<!-- wrong value-->
${param.my_param_name}

One way to get the job done if you are using tomcat (or something uses tomcat internally) is set URIEncoding="UTF-8" in Tomcat's <connector> settings within the "server.xml"

Thanks!
This also solves the Japanese language problem.
I modified /spring-insight-instance/conf/server.xml
But still why don't Roo support it...
