415 error when sending json data back to java rest service using AJAX
I have an ajax request on my front end that sends a JSON doc to a rest service implementation. It is wired up through Spring and the @GET request in the REST service works well.
The issue is that whenever i try to use the @POST method it always throws a 415 error.
I have tried manipulating how i send it back and the type of variable that is accepted in the post method according to various guides online but I am not sure where to look next.
I have double checked that i do have data being sent to the @POST method but I feel like it is not parsing the JSON at all and throwing the error.
Unfortunately i dont see how to fix that if it is the issue.
Below i have dumbed everything down to a simple form that still produces the 415 error.
AJAX Request:
function post_request(json_data) {
$j.ajax({
url : '../api/createDisplayGroup/postHtmlVar/' + containerID + '/' + containerType,
data: JSON.stringify(json_data),
dataType: 'json',
type : 'post'
}).done(function(response) {
run_update(response);
}).error(function(jQXHR, textStatus, errorThrown) {
alert('error getting request');
});
};
Spring XML:
<jaxrs:server id="displayGroupService" address="/createDisplayGroup">
<jaxrs:serviceBeans>
<ref bean="peopleFilterRestService" />
</jaxrs:serviceBeans>
<jaxrs:providers>
<ref bean="jacksonJsonProvider"/>
<!-- disable XHR token check - allow external sources to call the service -->
<!--ref bean="securityInterceptor" /-->
</jaxrs:providers>
</jaxrs:server>
<bean id="peopleFilterRestService" class="mil.milsuite.community.rest.PeopleFilterRestService">
<property name="peopleFilterService" ref="peopleFilterService"/>
</bean>
<bean id="peopleFilterService" class="mil.milsuite.community.members.service.PeopleFilterServiceImpl">
<property name="communityManager" ref="communityManager"/>
<property name="socialGroupManager" ref="socialGroupManagerImpl"/>
</bean>
REST Implementation (only @POST):
@POST
@Path("/postHtmlVar/{containerId}/{contentType}")
@Consumes(MediaType.APPLICATION_JSON)
public List<TabDefinition> postHtml(@PathParam("containerId") String containerId, @PathParam("contentType") String contentType, List<TabDefinition> displayGroups) {
Long contId = Long.parseLong(containerId);
Long contType = Long.parseLong(contentType);
//return convertToResponse(peopleFilterService.getDisplayGroups(contId, contType));*/
return testDisplayGroup();
}
The error you are receiving is as follows:
415 Unsupported Media Type
The request entity has a media type which the server or resource does not support. For example, the client uploads an image as image/svg+xml, but the server requires that images use a different format. (wikipedia)
The cause may be the $j.ajax call, try adding the contentType argument, eg:
...
$j.ajax({
url : '../api/createDisplayGroup/postHtmlVar/' + containerID + '/' + containerType,
data: JSON.stringify(json_data),
dataType: 'json',
type : 'post',
contentType: 'application/json'
...
This will then match the value of the @Consumes annotation used by your postHtml method, note that:
The @Consumes annotation is used to specify which MIME media types of representations a resource can accept, or consume, from the client. (Oracle)
By default the ajax call's media type will be application/x-www-form-urlencoded , so your handler method will not be matched, resulting in the 415 error.
Aside: In the ajax call, contentType specifies the type of data to be sent to the server whereas dataType specifies the type of data that will be returned.
