415 Unsupported Media Type with Spring 3.2
提问by Tiny
I'm trying to insert and/or update data into the database using the PUTmethod via JSON using jQuery 1.6, (Hymanson 2.1.1and Spring 3.2.0).
我正在尝试PUT使用 jQuery 1.6（Hymanson 2.1.1和 Spring 3.2.0）通过 JSON的方法将数据插入和/或更新到数据库中。
The JS code is as follows.
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);
}
});
}
The method inside the Spring controller which is mapped with the URL is as follows.
与 URL 映射的 Spring 控制器内部的方法如下。
@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;
}
The server responds as the question implies,
服务器响应问题暗示，

It works when I remove @RequestBody final MultiValueMap<String, String > data, a method parameter and simply use @PathVariableto accept request parameters.
当我删除@RequestBody final MultiValueMap<String, String > data一个方法参数并仅用于@PathVariable接受请求参数时，它会起作用。

The content type that the browser sends, Content-Type: application/json, does not seem to match @RequestBody final MultiValueMap<String, String > data.
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 > data。
Either:
任何一个：
Send
application/x-www-form-urlencoded(in which case you could easier use HttpPutFormContentFilterinstead).Or: change this into something like
@RequestBody final MyDTO dataas explained in JQuery, Spring MVC @RequestBody and JSON - making it work together.
发送
application/x-www-form-urlencoded（在这种情况下，您可以更轻松地改用HttpPutFormContentFilter）。或者：改变这种成像
@RequestBody final MyDTO data在解释了jQuery，Spring MVC的@RequestBody和JSON -使其协同工作。

I had the same problem, the way to solve it was removing @RequestBody and then taking the data from the request (with IOUtils from apache commons). It should be noted that I used the received data just for logging js errors.
我遇到了同样的问题，解决它的方法是删除 @RequestBody 然后从请求中获取数据（使用来自 apache commons 的 IOUtils）。应该注意的是，我将接收到的数据仅用于记录 js 错误。
/**
* this method logs with log4j the received js errors
*/
@RequestMapping(value = "/jsloggerservice/{applicationName}", method = RequestMethod.POST)
public void jsLogger(HttpServletRequest request, HttpServletResponse response) {
try {
String message = IOUtils.toString( request.getInputStream());
log.info("JAVASCRIPT-ERROR: " + message);
response.getWriter().write("OK");
}
catch (UnsupportedEncodingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

In the server side, in Spring 3, you need this:
在服务器端，在 Spring 3 中，你需要这样：
<bean id = "mappingHymansonHttpMessageConverter" class = "org.springframework.http.converter.json.MappingHymansonHttpMessageConverter" />
<!-- starting Spring MVC annotation usage，handling request and annotation pojo mapping-->
<bean class ="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" >
<property name= "messageConverters" >
<list>
<ref bean= "mappingHymansonHttpMessageConverter"/>
</list>
</property>
</bean>
Spring 4 uses mappingHymanson2HttpMessageConverter.
Without AnnotationMethodHandlerAdapterbean declaration, you can also use @RequestBody, while by declaring it we can set mappingHymanson2HttpMessageConverterto messageConverters. This is concluded by phenomena that I observed, if wrong please correct.
Spring 4 使用mappingHymanson2HttpMessageConverter. 如果没有AnnotationMethodHandlerAdapterbean 声明，您也可以使用@RequestBody，而通过声明我们可以将其设置mappingHymanson2HttpMessageConverter为messageConverters。这是根据我观察到的现象得出的结论，如有错误请指正。

Just in case somebody encounters this: I had two Methods
以防万一有人遇到这个：我有两个方法
void setLevel (Level level) void setLevel (String level)
void setLevel（级别级别） void setLevel（字符串级别）
in the Class annotated with @RequestBody and that also caused a 415.
在用@RequestBody 注释的类中，这也导致了 415。
