415 Spring 3.2不支持的介质类型 [英] 415 Unsupported Media Type with Spring 3.2
问题描述
我正在尝试使用jQuery 1.6使用 PUT 方法通过JSON插入和/或更新数据（Jackson 2.1.1 和Spring 3.2.0 ）。
I'm trying to insert and/or update data into the database using the PUT method via JSON using jQuery 1.6, (Jackson 2.1.1 and Spring 3.2.0).
JS代码如下。
var itemsArray=[];
var id;
function insertOrUpdate()
{
var i=0;
$('input[name="txtCharge[]"]').each(function()
{
isNaN($(this).val())||$(this).val()==''?itemsArray[i][2]='':itemsArray[i][2]=$(this).val();
i++;
});
$.ajax({
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
datatype:"json",
type: "PUT",
url: "/wagafashion/ajax/InsertZoneCharge.htm",
data: "items=" + JSON.stringify(itemsArray)+"&zoneId="+id+"&t="+new Date().getTime(),
success: function(response)
{
alert(response);
},
error: function(e)
{
alert('Error: ' + e);
}
});
}
Spring控制器中使用URL映射的方法如下所示。
The method inside the Spring controller which is mapped with the URL is as follows.
@RequestMapping(value=("ajax/InsertZoneCharge"), method=RequestMethod.PUT, produces=MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody String insertZoneCharge(@RequestBody final MultiValueMap<String, String > data, final HttpServletResponse response, HttpServletRequest request)
{
String message="";
try
{
Map<String, String> params = data.toSingleValueMap();
if(params.get("zoneId")==null||params.get("zoneId").equals("")||params.get("items")==null||params.get("items").equals(""))
{
response.setStatus(HttpServletResponse.SC_BAD_REQUEST);
}
else
{
message=zoneChargeService.insertZoneCharge(params.get("zoneId"), params.get("items"));
}
}
catch (IOException ex)
{
message="An error occured. Data can not be saved.";
Logger.getLogger(ZoneCharge.class.getName()).log(Level.SEVERE, null, ex);
}
return message;
}
服务器响应问题暗示，

当我删除 @RequestBody final MultiValueMap< String，String> data ，一个方法参数，只需使用 @PathVariable 来接受请求参数。
It works when I remove @RequestBody final MultiValueMap<String, String > data, a method parameter and simply use @PathVariable to accept request parameters.
推荐答案
浏览器发送的内容类型 Content-Type：application / json ，似乎与不匹配@RequestBody final MultiValueMap< String，String>数据。
The content type that the browser sends, Content-Type: application/json, does not seem to match @RequestBody final MultiValueMap<String, String > data.
要么：
-
发送
application / x-www-form-urlencoded（在这种情况下，您可以更轻松地使用 HttpPutFormContentFilter 而不是）。
Send
application/x-www-form-urlencoded(in which case you could easier use HttpPutFormContentFilter instead).
或者：将此更改为 @ RequestBody最终的MyDTO数据，如 JQuery，Spring MVC @RequestBody和JSON - 让它协同工作。
Or: change this into something like @RequestBody final MyDTO data as explained in JQuery, Spring MVC @RequestBody and JSON - making it work together.
