Spring mvc下Ajax获取JSON对象问题 406错误

spring 通过@ResponseBody标签返回JSON数据的方法都报406错： Failed to load resource: the server responded with a status of 406 (Not Acceptable) 以及报错描述： The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers () 

 

Spring  配置如下:

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:context="http://www.springframework.org/schema/context"

xmlns:mvc="http://www.springframework.org/schema/mvc"

xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd

http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd">

 

mediaTypes配置:                

        atom=application/atom+xml  

           html=text/html  

           json=application/json  

           *=*/*

用@ResponseBody返回对象出现问题，报406错误！！！

最后发现是：spring 时requestedMediaTypes却为[text/html]的情况报406错误，还有一个原因可能是由于采用的后缀有关，如果使用*.htm,*.html等，默认就会采用[text/html]编码，若把AJAX请求URL后面加上*.json,*.shtml等就OK！
