Spring @RequestParam garbled problem

Find a lot of information on the Internet to find a solution to the method, through the URL to pass the named parameters, the background received is garbled solution is as follows:

Method One: Re-encode the received parameters

@RequestMapping (value= "/handle") public string handle81 (@RequestParam ("UserName") string userName) {            username= New String (Username.getbytes ("iso-8859-1"), "UTF-8")    modelmap.put ("UserName", userName);    return "/user/showuser";}

Method Two: Configure in Web. xml

        <!--character Filters--  

Method Three: Modify Tomcat's Server.xml (under the Conf file) and find the following code to add uriencoding encoding.

    <connector port= "8080" protocol= "http/1.1"               connectiontimeout= "20000"               redirectport= "8443" URIEncoding= " UTF-8 "/>

Finally my solution when the method two and method three simultaneous use, no way to solve @requestparam garbled problem.
