[FIXED] Spring MVC, pass json object to controler and return view with model attributes set

Issue

I'm trying to send data to my controller, have it do a service call and then return the result to be displayed on the view

My Ajax call looks like this

$.ajax({
            url: "<c:url value="submitReportQuery"/>",
            type: "POST",
            dataType: "html",
            contentType: "application/json;",
            data: JSON.stringify(reportQueryMap),
            success: function (data) {
                $('#SelfServiceResults').html(data);
            }
        })

and my controller looks like this

@RequestMapping(value = "submitReportQuery", method = RequestMethod.POST, consumes="application/json" )
    public String submitReportQuery(@ModelAttribute Map<String, String> reportQueryMap/*, Model model, BindingResult bindingResult*/)throws Exception{
         //model.addAttribute("successful", true);
         return "queries/SelfServiceQueriesSubmitResults";
    }

The json object looks like this (it can have anything from 0-5 randomKeys) which I pass as a map to a service Note: the actual name of "randomKey" can change the key is a unknown

{
"randomKey1":"111",
"randomKey2":"222",
"randomKey3":"333",
"reportType":"Commission Processed BH",
"reportProduct":"LIFE",
"reportMonth":"January 2017",
"queryRemark":"nice"
}

I can't seem to get the "successful" attribute passed to the view, if I add the parts comented out I get this error

org.springframework.web.util.NestedServletException: Handler processing failed; nested exception is java.lang.NoSuchMethodError: java.lang.String submitReportQuery(java.util.Map)

I basically want This but it must return a view with attributes set on it

Solution

@RequestMapping(value = "submitReportQuery", method = RequestMethod.POST, consumes="application/json" )
public String submitReportQuery(@RequestBody ReportQueryMapBean reportQueryMap)throws Exception{
     //model.addAttribute("successful", true);
     return "queries/SelfServiceQueriesSubmitResults";
}

public class ReportQueryMapBean {
    // to do delcare the bean fields to match the request
    // and corresponding getter and setter function
}
