Content type 'text/xml' not supported

Question

I'm using springframework and have question about it!

$.ajax({
      type: "POST",
      url: "/updateCell.do",
      data: JSON.stringify(data),
      contentType: "application/json; charset=UTF-8",
      success: function(response) {
         sweetAlert('success','It has been successfully edited.','');
      },
      error: function(xhr, status, error) {
         sweetAlert('error','A problem has been detected.','');
      }
});

when I tried this ajax, which has 'application/json' content type

org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/json;charset=UTF-8' not supported

This error got happended... so I add

<property name="messageConverters">
            <list>
                <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"/>
            </list>
        </property>

this to 'dispatcher-servlet.xml' and it worked!

and then I tried to send ajax, which has 'text/xml' content type

var wfsTransactionRequest =
          '<wfs:Transaction ' + 
          'xmlns:wfs="http://www.opengis.net/wfs" ' +
          'xmlns:gml="http://www.opengis.net/gml" ' +
          'xmlns:ogc="http://www.opengis.net/ogc" ' +
          'xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" ' +
          'xmlns:feature="http://vndan" ' +
          'service="WFS" version="1.2.0" ' +
          'xsi:schemaLocation="http://www.opengis.net/wfs ' +
          'http://schemas.opengis.net/wfs/1.0.0/WFS-transaction.xsd">' +
              '<wfs:Update typeName="vndan:' + tableName + '">' +
                  '<wfs:Property>' + 
                      '<wfs:Name>geom</wfs:Name>' + 
                      '<wfs:Value>' + geomXML + '</wfs:Value>' + 
                  '</wfs:Property>' +
                  '<ogc:Filter>' +
                    '<ogc:FeatureId fid="' + fid + '"/>' +
                '</ogc:Filter>' +
              '</wfs:Update>' +
          '</wfs:Transaction>';




    $.ajax({
        url: '/gis/wfs',
        type: 'POST',
        dataType: 'xml',
        data: wfsTransactionRequest,
        contentType: 'text/xml',
        success: function (data) {
            toastr.success('It has been successfully edited.');
        },
        error: function (xhr, status, error) {
            console.error(error);
        }
    });

like this...

but in this case, Content type 'text/xml' not supported error happened. so I added

<bean class="org.springframework.http.converter.xml.MappingJackson2XmlHttpMessageConverter" />

this to 'dispatcher-servlet.xml', but nothing changed.

when I deleted

<property name="messageConverters">
            <list>
                <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"/>
            </list>
        </property>

this from 'dispatcher-servlet.xml', I could send ajax, which has text/xml content type, but couldn't send ajax, which has 'application/json' content type.

These codes worked well in another project, so I don't think it's a problem related to Server or other things...

To sum up, I can only send one of the two contents type. Is there anyway that I could send both ajax?

Here is my 'dispatcher-servlet.xml' :)
