Spring MVC Ajax编码

Question

Problem with encoding. Spring MVC controller receives from ajax char '?' instead 'ã' etc... Encoding on all page is utf-8, alert in javascript file show right chars, set up ajax, and adding filters do not work

*javascript* 

$.ajax({
    url : urlID,        
    contentType: "text/html; charset=utf-8",
    data : parameters,
    success : function(data, textStatus) {
        $(contentID).empty().html(data);
    },
    error : function(jqXHR, textStatus, errorThrown) {
        $("#errorMessage").empty().html(
                "<h3>Exception: " + errorThrown + "</h3>");
    }
});

Controller

@RequestMapping(value = "/marketing-changepage", method = RequestMethod.GET)
    public String marketingChangepage(HttpServletResponse response, @RequestParam String startDate,
            @RequestParam String endDate, @RequestParam String device,
            @RequestParam String source, Model model, Principal principal) {        
        AjaxRequestParams ajaxRequestParams = new AjaxRequestParams();
        ajaxRequestParams.setDateRange(new DateRange(startDate, endDate));
        ajaxRequestParams.setSource(source);
        ajaxRequestParams.setDevice(device.toLowerCase());
        ajaxRequestParams.setClientInfo(userService
                .fetchClientInfoByUserName(principal.getName()));

        preparePage(ajaxRequestParams, model, principal);
        return "marketing/content_marketing";
    }

Answer 1

just configure your server.xml file and add attribute URIEncoding="UTF-8" like the following :

  <Connector port="8080" maxHttpHeaderSize="8192"
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" redirectPort="8443" acceptCount="100"
               connectionTimeout="20000" disableUploadTimeout="true"
               URIEncoding="UTF-8"
   />

and please refer to this wiki here , about Character Encoding in Tomcat .
