Spring mvc @ResponseBody jquery ajax调用出现如下错误：406 Not Acceptable

jQuery.ajax({
type: "POST",
url: "ajax/ajaxCheckLoginName.do",
data: "username="+$("#name").val(),
error: function(XMLHttpRequest, error, errorThrown){
alert(error);
alert(errorThrown);
},
success: function(response){
if(response==1){ $("#name").removeClass("extra");}
}
});

controller执行正常，jquery.ajax始终无法执行回调函数

加入错误查看代码：

error: function(XMLHttpRequest, error, errorThrown){
alert(error);
alert(errorThrown);
},

提示： Not Acceptable

The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers ().

需要加入jackson依赖：
