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

来源：互联网发布：心电图数据正常值编辑：程序博客网时间：2024/06/05 16:37

  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：
