spring - Get Parameter Encoding

Question

I have a problem using spring mvc and special chars in a GET request. Consider the following method:

@RequestMapping("/update")
public Object testMethod(@RequestParam String name) throws IOException {
    }

to which I send a GET request with name containing an "?" (german umlaut), for instance. It results in spring receiving "?¤" because the browser maps "?" to %C3%A4.

So, how can I get the correct encoded string my controller?

Thanks for your help!

You're having this problem, because the request differentiates between body encoding and URI encoding. A CharacterEncodingFilter sets the body encoding, but not the URI encoding.

You need to set URIEncoding="UTF-8" as an attribute in all your connectors in your Tomcat server.xml. See here: http://tomcat.apache.org/tomcat-6.0-doc/config/ajp.html

Or, alternatively, you can set useBodyEncodingForURI="True".

If you're using the maven tomcat plugin, just add this parameter:

mvn -Dmaven.tomcat.uriEncoding=UTF-8 tomcat:run
