不支持内容类型“text/xml”

问：

我正在使用springframework 并对此有疑问！

$.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.','');
      }
});

当我尝试这个具有“application/json”内容类型的ajax时

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

这个错误发生了...... 所以我加上

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

这到“调度程序-servlet.xml” 它奏效了！

然后我尝试发送ajax，它具有“text/xml”内容类型

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);
        }
    });

喜欢这个。。。

但在这种情况下，错误发生了。 所以我加了Content type 'text/xml' not supported

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

这到“调度程序-servlet.xml”，但没有任何变化。

当我删除时

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

来自“调度程序-servlet.xml”，我可以发送具有文本/xml 内容类型的 ajax，但无法发送具有“application/json”内容类型的 ajax。

这些代码在另一个项目中运行良好，所以我不认为这是与服务器或其他事情有关的问题......

综上所述，我只能发送两种内容类型中的一种。 无论如何，我可以发送两个ajax吗？

这是我的“dispatcher-servlet.xml”:)
