1.修改： contentType 为text/html
2.注解修改如下：
@RequestMapping(value = "/save",method = RequestMethod.POST,produces = "application/json;charset=UTF-8")
@ResponseBody
改为
3.其他解决方法（本人没用到）：
在IE9下，将json字符串用下面的格式返回给客户端
<body>
<pre>{"message":"保存成功","data":null,"success":true}</pre>
</body>
本人部分代码如下：
@RequestMapping(value = "/importExcel/check",produces = "text/htm;charset=UTF-8")
@ResponseBody
public Result importExcelView(MultipartFile file,HttpServletResponse response) throws Exception {
response.setContentType("text/html;charset=utf-8");
补充：
发现返回数据为：
<h1>HTTP Status 406 - </h1><hr size="1" noshade="noshade"><p><b>type</b> Status report</p><p><b>message</b> <u></u></p><p><b>description</b> <u>The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers ().</u></p><hr size="1" noshade="noshade"><h3>Apache Tomcat/7.0.26</h3>解决办法：将 返回 类型 Result 改为 String 类型。
