Spring 2.5.x MVC portlet with annotation & AJAX with jQuery+JSON Error: Content Type cant be set to json

When i try to use spring 2.5.x DispatcherPortlet with liferay to use Ajax, i am getting this error. I have configured it using annotations.

At class level i used following annotations,

Code for controller...

@Controller
@RequestMapping("VIEW")
public class MyController {

@SuppressWarnings("unchecked")
 @RequestMapping(method=RequestMethod.GET) //this is default rendering...
 public String defaultRender(Model model, PortletRequest request) {
 ...
 return "/some/someview";
 }


@RequestMapping(method=RequestMethod.POST,params="action=something") // For ajax call...using jQuery
 public ModelAndView processTotalMatchCount(RenderRequest request, Model model) throws IOException {
  Map<String,String> hmapStockSearchParams = getSomeData(request);  
  Integer totalMatches = service.getTotal(hmapStockSearchParams);
  Map map = new HashMap();
  map.put("totalMatches", totalMatches); 
  return new ModelAndView("ajaxView",map);
 }

}

From JSP i am calling following JS function using jQuery.

function fetchTotalMatches(){ 
 var url = "<portlet:renderURL><portlet:param name='action' value='something' /></portlet:renderURL>";
  jQuery.ajax({ url: url,
    method: 'POST', 
    //dataType:'json', when i enable this it goes in error bcs response is not in JSON format...
    data: {param1:'one',param2:'two'},      
    success: function(message) {
     alert(message);
     jQuery('input:hidden[@name="total"]').val(message.totalMatches);     
     jQuery('div.secondary-nav').children('div.viewMatches').
      html(message.totalMatches);
    }, 
    error: function(xhr, ajaxOptions, thrownError) {
     alert(xhr.status + " - " + xhr.statusText);
    }
   }
  );
}

When i enable dataType:'json' in jquery call, it goes in error function. Otherwise i will get the response alert of the whole HTML of the page defined in defaultRender method (The same jsp from which i m calling this function. )

And in console i am getting this error...

please help regarding this. What am i missing?

I have used Ajax related Resolver and View as per this link...

Basically its not allowing to set content type to application\json as per the below class

public class AjaxView extends AbstractView {
 private static final Log log = LogFactory.getLog(AjaxView.class);
   private static final String REQUEST_CONTEXT_ATTRIBUTE = RequestContext.class.toString();

 public AjaxView() {
//  super();  
  setRequestContextAttribute(REQUEST_CONTEXT_ATTRIBUTE);
     setContentType("application/json;charset=UTF-8");     
 }
    /* (non-Javadoc)
     * @see org.springframework.web.servlet.view.AbstractView#renderMergedOutputModel(java.util.Map, javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse)
     */
    @Override
    protected void renderMergedOutputModel(Map map, HttpServletRequest request, HttpServletResponse response) 
    throws Exception {
        log.info("Resolving ajax request view - "+map);        
        JSONObject jsonObj = new JSONObject(map);
        log.info("content Type = " + getContentType());     
//        response.reset();
        response.setContentType("application/json");
        response.setCharacterEncoding("UTF-8");
        response.getWriter().write(jsonObj.toString());
        response.getWriter().flush();
    }
}

Please help ASAP. What i need is, Ajax call returning JSON string in spring 2.5.x MVC Portlet...

thanks in advance.

If you want JSON functions in spring MVC portlet you have to use resource mapping not request mapping!

I'm not sure about the out of the box support for Spring MVC for JSON, in Spring I never tried it (I mean @ResponseBody)

What I do to generate JSON in Spring MVC portlet, I make a JSP page for JSON purpose inside that JSP 

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@page contentType="application/json; charset=UTF-8" pageEncoding="UTF-8" %>
<c:out escapeXml="false" value="${outObject}"/>

and in the controller 

     @ResourceMapping("the id for calling from client side")
     public ModelAndView countryRequest(ResourceRequest request, ResourceRequest response) {

.... omit 

    Map<String, String> model = new HashMap<String, String>();
    model.put("outObject", json);
    return new ModelAndView("ajaxResponse", model);
}

You will get the result on success method, for example:

function <portlet:namespace/>changeSicGroup(){
var sicGroupId = jQuery('#<portlet:namespace/>addBranchsicGroup').val();
jQuery.ajax({
    url: '<portlet:resourceURL id="showSicSector" />',
    global: false,
    type: "POST",
    dataType:'json',
    data: {sicGroupId : sicGroupId}
    ,async:false
    ,success: function(result){
        var targetCom = jQuery('#<portlet:namespace/>addBranchSicSector');
        if(result != null){
            //                    jQuery("#"+targetComId).show();
            targetCom.find('option').remove();
            targetCom.append('<option value=""><spring:message code="pleaseSelectSicSector"/></option >');
            for(var i=0;i< result.length;i++){
                targetCom.append("<option value="+result[i].sectorCode+">"+result[i].desc+"</option>");
            }
            //                    targetCom.attr('disabled',false);
        }else{
            targetCom.find('option').remove();
            targetCom.append('<option value=""><spring:message code="pleaseSelectSicSector"/></option >');
            //                    jQuery("#"+targetComId).hide();
        }
    }
});

I have not found the solution with spring 2.5.

So I upgraded to 3.0.3 and tried to use ContentNegotiatingViewResolver with JSON. But it was failing.

check the question ERROR: 'ContentNegotiatingViewResolver'of Spring 3.0.3 MVC Portlet+JSON for a detailed explanation on Spring 3.0.3 of my problem.

Finally, I found that Spring 3 is not supporting portlet JSON. So I moved to servlet and not using spring MVC for json. Only for JSPs...i'm using it.

It seems to me you should use following

  • use dataType:'json'
  • use contentType: "application/json; charset=utf-8"
  • use JSON.stringify to convert your data (every property separately) which you gives per data parameters.

you can see under How do I build a JSON object to send to an AJAX WebService? an example how to make JSON-encoding. Another link Can I return JSON from an .asmx Web Service if the ContentType is not JSON? can be probably also helpful.
